MVT22B Thermocouple / Millivolt Input Module for the XR440 Pocket Logger. MVT Module converts the 4 input channels as follows: Channel 1: Precision thermistor for ambient temperature or CJC readings; Channels 2 & 4: Standard Inputs (0-5vDC, Pace Sensors or resistive inputs); Channel 3: mV or Thermocouple Inputs, mV Range: ±22mV with a 24µV resolution. Thermocouple Input suitable for Type J, K, N, R, S, T, B, C, E Thermocouples. Module adds 9mm to overall length of an XR440.
