Advanced IR Sensor

This technology is indeed one of the most notable features of Kintrex IRT0421. This IR thermometer has a remarkable detector system that will surely defy all odds. It has the ability to detect the invisible heat which other thermometers cannot do. This system works by giving you the thermal information of a particular object. You will have the benefit of receiving the real-time and precise thermal measure of the object you are testing.

This IR thermometer measures the infrared energy being emitted by the object, which is impossible to be seen by the human eye. As long as the object has an above-zero temperature, it is already considered to emit heat. This advanced IR sensor will help you in identifying the exact temperature of an object. This is the reason why you can use it for both electrical and mechanical purposes. It will surely be able to give you the most accurate reading.

Auto Shut-Off Feature

The Kintrex IRT0421 is operated by two AA batteries. This IR thermometer has an automatic shut-off feature that will definitely help in prolonging the life of the batteries.

You don’t need to worry because your device will still run upon switching it on.

Another feature that you will like is its wide temperature range from -60 to 500 degrees Celsius. If you check the backlit display, you will be able to see the current and maximum temperature reading. It has an ability to record these measurements for future use. You will be able to retrieve all the readings as well with this feature.

Some IR thermometers in the market don’t have this feature. Since Kintrex IRT0421 is designed for the convenience of the users, almost all the necessary functions are included. It will surely give you all the convenience you’ll need.
