The model NV602 is a versatile temperature monitoring instrument for liquid Helium and above. It is used to measure the temperature from 3.2 K to 410 K. It uses the DT 470 / DT670 silicon diode sensor. It has 1 sensor input. The measurement input is designed for the demand of cryogenic temperature measurement, however it monitors low noise, high resolution and wide operating range which makes it ideal for noncryogenic application as well. It produces linearized 0-10V, 4-20mA and RS232 outputs for external interfacing.
