The TA-350P and TA-650P Dry Block Calibrators perform functions that would require three different types of instruments: a dry block, standard thermometer and electronic calibrator measuring signals generated by RTDs, thermocouples, thermoswitches and mA generating sources. Besides these functions they have HART® Communication Protocol, data logger mode, Ethernet and USB interface.

• The TA-350P and TA-650P models generate from ambient temperature to 350 ºC and 650 ºC, respectively, with a resolution of 0.01 ºC.
• Optional temperature measurement and control by external probe with Callendar-Van Dusen coefficients.
• Using the internal reference, accuracy of up to ±(0.1 ºC + 0.1 % of reading).
• Using the external probe, accuracy of up to ±0.07 °C for TA-350P and ±0.10 °C for TA-650P.
• Using an external thermometer such as Presys Super Thermometer ST-501, accuracy of up to ±0.05 ºC.
• Stability of ±0.05 ºC.
• Uniformity of ±0.05 ºC.
• 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 calibration software.
• Portable, compact, with carrying case and interchangeable inserts.
