model td7600, a reference calibrator for thermal meters and process signals. the accuracy class is 0.003, it can calibrate the process signal calibrators with class 0.01 and below, and calibrate the thermal process instruments such as industrial sensors, transmitters and recorders.

meet the requirement of jjf 1472-2014 calibration specification for process calibrators. (tunkia is involved in drafting)



support output or measurement of following electrical parameters: dc voltage, dc current, resistance, pulse signal, etc.

 support equivalent simulation and measurement of various thermal resistances (rtd), 4-wire resistance measurement mode.

 support equivalent simulation and measurement of various thermocouples (tc), and automatic temperature compensation without external compensating elements.


 the output and measurement can be performed simultaneously, the information of source and meter are displayed separately, and any channel can be closed off at any time.

 good electrical isolation between the channels to ensure the accuracy for a long time.

 the equivalent output or measurement values of rtd and tc can be displayed in the form of electrical parameter or temperature.

 provide dc voltage of 24 v as auxiliary power supply for transmitters (loop mode).

 complete electrical protection such as electrostatic protection and instantaneous overload protection of voltage and current, can adapt to complex industrial applications.

 large lcd touch screen, more intuitive of value display

 select the proprietary calibration software with computer to build full-automatic calibration system.

 the proprietary calibration software has built in multiple calibration solutions for dozens of process signal calibrator manufacturers at home and abroad.

 the proprietary calibration software has powerful data management, and supports customized templates to generate calibration reports.
