Infrared thermometers are non-invasive, modern instruments that measure temperature without direct contact. This device is widely used in healthcare, industrial, and domestic settings and has become important, particularly when hygienic, quick readings are needed.
This blog discusses what an infrared thermometer is, how it works, and its types and uses.
What is an Infrared Thermometer?
An infrared thermometer is a device that measures temperature by detecting infrared radiation emitted by an object. It does not require physical contact, unlike traditional thermometers, and can thus be used for quick and safe temperature checks.
These devices are used when measuring temperature for medical diagnoses, inspecting industrial machines, and monitoring food safety.
How Does an Infrared Thermometer Work?
All objects emit infrared radiation according to their temperature. The thermometer uses these to measure the object’s temperature.
The step-wise working of infrared thermometers is as follows:
- The device captures infrared radiation from the target.
- The radiation is concentrated on a sensor.
- This is then converted into electrical energy by the sensor.
- The reading is shown in a digital form.
Types of Infrared Thermometers
Infrared thermometers available on the market are of three types, each designed for a different use case.
1. Digital Infrared Thermometer
- The most common one is a digital infrared thermometer, particularly in the health sector. It has digital readings and is user-friendly. They are commonly found in clinics, hospitals, and homes.
2. Non-Contact Infrared Thermometer
- A non-contact infrared thermometer enables its users to measure temperature without coming into contact with the object or person. This makes it hygienic and suitable for mass screening, particularly in public areas.
3. Industrial Infrared Thermometer
- An industrial infrared thermometer is used for high-temperature settings and equipment. Industrial infrared thermometers are durable and can measure extremely high temperatures in factories and workshops.
Uses of the Infrared Thermometer
There are multiple infrared thermometer uses extending to a variety of industries:
- In healthcare, it is used for rapid and safe measurement of body temperature.
- In industries, for monitoring machines and equipment.
- The food industry uses it to ensure safe and proper storage of food.
- It is also used for electrical checks to identify overheating elements.
- In automotive, it helps check engine temperatures.
Infrared Thermometer Range and Accuracy
The infrared thermometer’s range varies by device type. Medical thermometers usually measure between 32 and 42 degrees Celsius, whereas industrial thermometers can measure much higher temperatures.
Its accuracy depends on:
- Distance from the object.
- Calibration of the device.
- Environmental conditions
Advantages and Disadvantages of an Infrared Thermometer
Knowing the pros and cons of infrared thermometers helps you make better decisions.
Pros:
- Non-contact and hygienic
- Instant results
- Easy to use
- Versatile for many applications
Cons:
- Affected by environmental factors
- Proper calibration required
- May give out incorrect readings if not used correctly
How to Use an Infrared Thermometer
Knowing how to use an infrared thermometer guarantees correct results.
This is how you should use the thermometer:
- Turn on the device
- Point it towards the forehead or object.
- Maintain the recommended distance.
- To measure, press the trigger.
- Read the displayed temperature.
Infrared Thermometer for Industrial Use
Infrared industrial thermometers are important in ensuring safe operations. It assists in identifying overheated equipment, preventing failures, and ensuring efficiency.
Manufacturing, power plants, and the automotive industry are among those that extensively use industrial infrared thermometers for routine inspections.
Infrared Thermometer Calibration
Infrared thermometers need calibration to maintain accuracy.
Calibration involves the following:
- Comparison of readings with a standard reference.
- Adjusting the device if necessary.
- Following manufacturer guidelines
Infrared Thermometer Price in India
The price of an infrared thermometer depends on the type, brand, and features.
The factors that affect its price are:
- Accuracy and range
- Build quality
- Brand reputation
- Other functions, such as memory storage.
Typically, thermometers used for medical and industrial purposes cost around INR 600 to INR 2000 and INR 1000 to INR 6000, respectively.
