Ever wonder if an infrared thermometer is best used to measure the temperature of food or equipment, solids or liquids?
Infrared (IR) thermometers are useful for measuring temperature in a variety of industrial and clinical settings.
Using a food thermometer is the only reliable way to ensure safety and determine the desired “doneness” of meat, poultry, and egg products. To be safe, these foods must be cooked to a safe minimum internal temperature to destroy any harmful microorganisms that may be in the food.
Infrared thermometers can be very useful when used in the right way and put to work in the right applications. However, before you can develop confidence in its ability to deliver rapid temperatures, you must understand its limitations.
What do infrared thermometers measure?
Infrared thermometers use the concept of infrared radiation to determine the surface temperature of objects without any physical contact. Let’s find out what infrared radiation is to better understand how IR thermometers work.
How do infrared thermometers work?
Similar to visible light, it is also possible to focus, reflect or absorb infrared light. Infrared thermometers use a lens to focus the infrared light emitted by the object onto a detector known as a thermopile.
Thermopile is nothing but thermocouples connected in series or parallel. When infrared radiation falls on the surface of the thermopile, it is absorbed and converted to heat. The voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which is displayed on the screen.
While this whole process may seem complicated, it takes just a few seconds for the infrared thermometer to record the temperature and display it in the desired unit.
An Infrared Thermometer is a handheld device that can display a temperature readout on it after scanning portions of an object or area with the built-in laser.

SpO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen. What are Spo2 normal values?
The body needs there to be a certain level of oxygen in the blood or it will not function as efficiently.
Human beings depend on oxygen for life. All organs require oxygen for metabolism but the brain and heart are particularly sensitive to a lack of oxygen.
Oxygen saturation levels below 95% are considered abnormal, and the brain may be affected when SpO2 levels drop below 80 to 85 percent. So what are normal Spo2 values?
SpO2 normal range
Normal pulse oximeter readings typically range from 95 to 100 percent. Values below 90 percent are considered low and indicate the need for supplemental oxygen. This condition is often referred to as hypoxemia, and its symptoms include severe shortness of breath, increased heart rate, and chest pain.
For people with chronic lung conditions and other breathing problems, the “normal” SpO2 range of 95% to 100% does not apply.
These individuals should always consult with their physician for information on acceptable oxygen levels for their unique health condition.
With that said, here are some general guidelines on normal SpO2 values for people with acute respiratory problems and chronic illnesses:
In a patient with acute respiratory illness or difficulty breathing, an SpO2 of 92% or less may indicate the need for supplemental oxygen.
In a patient with stable chronic disease, an SpO2 of 92% or less should prompt referral for further investigation of the need for long-term oxygen therapy.
Blood oxygen level normal range
Why is it important to have my blood oxygen level checked?
If you have a lung disease, your blood oxygen level may be lower than normal. This is important to know because when your oxygen level is low, the cells in your body can have a hard time working properly.
Oxygen is the “gas” that makes your body “go,” and if you are low on “gas,” your body does not run smoothly. Having a very low blood oxygen level also can put a strain on your heart and brain.
Most people need an oxygen saturation level of at least 90% to keep their cells healthy.
Having an oxygen level lower than this for a short time is not believed to cause damage. However, your cells can be strained or damaged if low oxygen levels happen many times.
If your oxygen level is low on room air, you may be asked to use supplemental (extra) oxygen.
The oximeter can be used to help see how much oxygen you need and when you may need it. For example, some people need more oxygen when asleep than when awake.
Some need more oxygen with activity than when at rest.
Spo2 Normal Values
When should I seek medical help?
This table provides guidance on what the oxygen level number means and when and how to seek medical help.
Oxygen Level
Guidance
90% or less
This oxygen level is very concerning and may indicate a severe medical problem. You may need an urgent x-ray or heart test.
91% to 94%
This oxygen level is concerning and may indicate a medical problem. Call your health care provider immediately.
91% to 94%
This oxygen level is normal. Walk around for two minutes and measure your oxygen level again. If your oxygen level falls below 95%, follow the instructions above.
Spo2 Normal Values
What is spo2
SpO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen.
What is PI in oximeter?
The perfusion index (PI) derived from a pulse oximeter is calculated as the ratio of the pulsatile blood flow to the non-pulsatile blood in peripheral tissue and can be measured non-invasively. PI can be used to assess peripheral perfusion dynamics due to changes in peripheral vascular tone.
what is oxygen saturation percentage?
Oxygen saturation, or “O2 sats,” indicates the amount of oxygen traveling through your body with your red blood cells. Normal oxygen saturation is usually between 95% and 100% for most healthy adults.
The air comes into the compressor after being compressed by the air inlet filter unit, and then it enters into the molecular sieve tower to separate the oxygen and nitrogen.
The oxygen successfully goes through the molecular sieve tower into the fine sieve tower.
Instead, the nitrogen is absorbed by the molecular sieve, then discharged to the atmosphere through the separator valve. The oxygen concentration is improved in the fine screen tower and the flow meter controls the size of the flow.
Then the oxygen is humidified by the humidifying water tank. Finally, the oxygen reaches the user through an oxygen supply tube.
Oxygen Concentrator Working Principle
Working principle of oxygen concentrator
Smallest Portable oxygen concentrator
The concentrator draws in room air and passes it through a series of filters that remove dust, bacteria, and other particulates.
In the first step of the concentration process, a compressor forces air into one of the two cylinders containing sieve material, where nitrogen is adsorbed, leaving concentrated oxygen and a small percentage of other gases found in room air.
Simultaneously, in the other cylinder, nitrogen is desorbed and exhausted into the atmosphere. In the second step, the function of the cylinders is reversed in a timed cycle, providing a continuous flow of oxygen to the patient.
Operating steps
The concentrator is properly set up by an expert.
Unit is plugged in to a power source, turned on, and the oxygen flow is adjusted as prescribed by a doctor.
A nasal cannula or mask is applied to the patient.
The concentrator is used for the prescribed amount of time, typically continuously for days or weeks at a time.
oxygen concentrator principle of operation
How does the oxygen concentrator work?
Air contains a mixture of oxygen and nitrogen. The Oxygen Concentrator is about the size of a small refrigerator in which the air is forced under pressure through molecular sieve beds filled with Zeolite which binds the nitrogen, and separates it from the air as in gas chromatography, thus increasing the proportion of oxygen from about 21% to about 90%.
This is how it works:
The air first passes through the four filters (explained below) which remove bacteria and dust.
The air is then forced by a compressor into canisters.
The canisters contain molecular sieve beds filled with zeolite (aluminium silicate) which binds the nitrogen and separates it from oxygen, thus increasing the oxygen concentration to as high as 90%.
Two canisters are used, the period of oxygen outflow from one coinciding with the discharge of nitrogen from the other, so that a continuous supply of oxygen enriched gas is delivered to the storage vessel.
Oxygen Concentrator Working Principle
How does an oxygen concentrator work?
The way an oxygen concentrator works is simple. It uses the surrounding atmosphere to create oxygen-rich air, by introducing filtered air from the environment into the oxygen machine, compressing it, purifying it, and removing nitrogen and other impurities. The patient is then given purified, oxygen-rich air.
How do i know if my oxygen concentrator is working?
Like any electrical equipment, an oxygen concentrator can stop working due to technical problems. There may also be cases where it may malfunction due to external influence, with no problems in the hub itself. If an oxygen concentrator is not providing oxygen, it could be for a number of different reasons. The system in an oxygen concentrator is made up of some intricate parts that work together to purify and deliver medical grade oxygen, so you can inhale it. However, before calling a service technician, you can troubleshoot the problem yourself to see if you can fix the problem yourself, check the filters, battery, or electrical contact.
The Oxygen Concentrator is intended for individual use as an oxygen supplement device in a home or care facility. The patient is the intended operator.
The oxygen concentrator uses pressure swing adsorption technology. At normal temperature, the machine will continuously separate oxygen from the air.
The medical oxygen concentrator is composed of filter system, compressor, adsorption tower, electrical control system, humidifier system and air system.
It adopts the advanced transformation absorption principle. It separates the oxygen and nitrogen under common temperature and pressure, then get the medical oxygen which meets the medical standards.
Oxygen Concentrator Parts and Functions
