Product Features

12-Channel Measurement

Simultaneously monitor 12 channels for comprehensive temperature profiling.

Adjustable Current & Reversal

Eliminate polarity and self heating probe errors with three automatic or user-selectable current modes for enhanced accuracy as good as ±2 mK.

THERMOtelligent™

Smart 4-wire PRT support. Probes retain their calibration data, removing the chance of input error no matter how many times you reconnect a probe.

Multiple Coefficient Modes

 Each channel can be programmed with ITS‐90 or Callendar‐Van Dusen coefficients to convert from resistance to temperature, no matter how you calibrate your probes.

Intuitive Touch Screen Interface

A full-color, pinch/zoom display simplifies data visualization and control.

Robust Data Logging

Automatically logs data to a USB flash drive, internal memory, or export to a computer with RHS control, ensuring reliable data logging.

Internal Reference Resistors

Four high-stability, high-precision, resistors provide drift compensation to significantly reduce overall uncertainty.
