TM290 has 8 channels of input and supports almost all diode and resistance temperature sensors. TM290 can simultaneously display the Kelvin (K), Celsius (℃), voltage (V), or resistance (Ω) of eight channels on the screen. The input terminals of TM290 are designed according to the requirements of low-temperature testing, but its low noise, high resolution, and large range make it suitable for testing in other temperature zones. TM290 has two types of computer interfaces for system integration and...

The DT64 series of silicon diode thermometers utilize specially designed silicon diodes suitable for low-temperature temperature measurements. Compared to ordinary silicon diodes, the DT64 series silicon diodes are characterized by good repeatability, low dispersion, and easy measurement at low temperatures due to the relatively high temperature dependence of the resistance value. All DT64 series silicon diode thermometers follow a voltage-temperature (V-T) curve better, resulting in better inte...
