Dry Blocks TA-25N, TA-35N & TA-50N

The TA-25N, TA-35N and TA-50N Dry Block Calibrators perform functions that would require three different types of instruments: dry block calibrator, standard thermometer and calibrator for TCs, RTDs, mA, mV, ohms and thermoswitches. Besides these functions they have HART® Communication Protocol, data logger mode, Ethernet and USB interface.

  • TA-50N generates the coolest temperature provided by a dry block. It reaches –50 ºC in an ambient temperature of 23 ºC, with no need of well insulator and no need to place it in a low temperature room.
  • Optional temperature measurement and control by external probe with Callendar-Van Dusen coefficients.
  • Accuracy of up to ±0.1 ºC with the internal reference, ±0.07 ºC with the external probe or ±0.05 ºC using an external thermometer such as Presys Super Thermometer PT-511.
  • Resolution of 0.01 ºC.
  • Stability of ±0.02 ºC for the entire range of temperature.
  • Input for RTD, thermocouples and thermoswitches.
  • Internal regulated 24 Vdc power supply and mA input for 2-wire transmitters.
  • External reference thermometer not necessary.
  • Completely automatic calibration with or without the use of a computer.
  • Documenting capabilities: connection with computer and ISOPLAN-5 calibration software.
  • Portable, compact, with carrying case and interchangeable inserts.
