Dry Block Low temperature calibrators.

T-25N Low temperature Dry Block calibrator. Temperature from -25°C to 125°C .
T-35N Low temperatur Dry Block calibrator. Temperature from -35°C to 125°C.
T-50N Negative temperature Dry Block Calibrator. Temperature from -55°C to 125°C.

T-25N, T-35N and T-50N Dry Block Calibrators perform functions that would require three different types
of instruments: dry block, standard thermometer and calibrator for TCs, RTDs, mA, mV, ohms and thermo

Low temperature Dry Block

Model  Description 
T-25N  T-25N Dry Block Calibrator. Temperature from -25°C.
T-35N  T-35N Dry Block Calibrator. Temperature from -35°C.
T-50N  T-50N Dry Block Calibrator. Temperature from -50°C.

Accomplish completely automatic calibrations with or without the use of a computer.
Documenting capabilities: communication with computer and CS-504 Calibration Software.
Portable, compact, provide interchangeable inserts and carrying case.

Dry Block Calibrator Accuracy
T-25N, T-35N and T-50N up to 0.1°C with internal reference or 0.05ºC with external thermometer,
such as Super Thermometer ST-501.

Dry Block Calibrator Resolution: 
T-25N, T-35N and  T-50N 0.01°C.

Stability of:
T-25N, T-35N  and T50N ±0.02°C through temperature range.
Presents input for thermocouples, thermo resistance and thermo switches.
Besides generating temperature, they measure the signal from the sensor being calibrated.
Perform TC readings with high precision internal cold junction compensation.
Internal regulated 14VDC power supply and mA input for 2-wire transmitters. Make no use of external
standard thermometers.
