The model NV604 is a versatile temperature monitoring instrument for liquid Helium and above . It is used to measure the temperature from 3.2 Kelvin to 410 Kelvin. It uses the DT 470 / DT 670 silicon diode sensor. It has 8 sensor inputs. 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.
