The RTM-1 digital reference thermometer is a desktop device designed and manufactured by Gometrics for indicating temperature with a very high level of precision and an extremely high long term stability, giving it a level of reliability only found in sophisticated laboratory instruments.

The measuring circuit of the RTM–1 reference thermometer self-calibrates against an internal resistance standard, ensuring the stability needed for reliable measurements.

The keyboard of the RTM-1 reference thermometer allows the deviation function coefficients to be entered which, when read directly in ºC achieves a precision of 0,01 ºC in any value of the calibrated range between –200 and +200 ºC and 0,02 ºC between +200 ºC and +660 ºC, stable for one year.
