Calibration Baths
(large calibration volume)


TA-25NL, TA-35NL and TA-45NL are part of a family of calibration baths designed for large calibration volume. This Calibrators family is ideal to calibrate sensors that require deep insertion. They also have HART® Communication Protocol, data logger mode, Ethernet and USB interface.

  • 3 in 1 Temperature Calibrators: dry block, stirred liquid bath for glass thermometers and any shape of temperature sensors and a Black Body source for infrared pyrometers.
  • Calibration volume of 35 x 160 mm.
  • TA-25NL, TA-35NL and TA-45NL generate temperatures from -25°C to 155°C and -45°C to 155°C, respectively, in an ambient temperature of 23°C.
  • Optional temperature measurement and control by external probe with Callendar-Van Dusen coefficients.
  • Accuracy of up to ±0.1°C with the internal reference, ±0.07°C with the external probe or ±0.05°C using an external thermometer such as Presys Super Thermometer ST-501.
  • Stability of ±0.02°C.
  • Uniformity of ±0.05°C.
  • 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.
