The RTM1-8 reference digital thermometer is a benchtop instrument designed and manufactured by Gometrics for temperature indication with a very high level of precision and extremely high stability over time, giving this instrument a degree of reliability only offered by sophisticated laboratory instruments.

The RTM1-8 temperature monitor accepts RTD and thermocouples. It incorporates a 16-bit microprocessor for characterization calculations in resistance-temperature conversion (for RTD) and voltage-temperature conversion (for TC).

The equipment implements in its mathematical algorithms the decaracterization polynomials, making the conversion error Ohms or mV – temperature 10 times less than the resolution of the instrument.

The RTM1-8 incorporates a 24-bit resolution A/D converter, which together with the electronic circuit design achieves high repeatability and measurement reliability.
