The ground signal processing of 140 series far infrared non-contact thermometer is completely digital, which means that the sensing signal will be digitized immediately and continue to be processed in the form of digital signal. Therefore, the IS140/IGA140 series infrared thermometers have achieved quite high accuracy and repeatability, as well as quite wide temperature measurement range.

Precision: The high precision of measurement is achieved through digital linearization of the sensing signal and fast and accurate compensation for the ambient temperature. The user can freely set the temperature measurement range within the limit of the basic temperature measurement range. Therefore, the analog output signal of the thermometer can also adapt to the selected temperature measurement range. The accuracy and repeatability will not change within the reset local temperature measurement range. These advantages facilitate the customer's storage of spare parts and the replacement of aging thermometers in use. The spare parts in the instrument have been able to adapt to the local temperature measurement

Output current: as the measurement output, there are two kinds of analog outputs 0... 20mA and 4... 20mA for selection. Through these two interfaces, users can also control the bus function of the thermometer through an external computer: RS485 interface is used to connect the thermometer to the existing bus system

Calibration: calibration of 140 series infrared thermometer can be realized by an external computer and a calibration radiator without opening the instrument
