Features

HT824 multifunctional process calibrator has high accuracy, high stability, can be widely used in site calibration of industry instruments and equipment in laboratory. Powerful functions, it can simulate to output voltage in millivolt and volt, current in milliampere, and many types of electric signals needed by the measurement and control during industry control process. It can also test or simulate kinds of TC and RTD signals.
5 1/2 digit input/output display.
Manual/auto cold junction compensation and setting.
The temperature value can be directly measured/output.
Auto power off when the voltage of battery is low.
Apply advanced built-in battery management system. 7.4V/7800mAh lithium battery, which can easily last for over 8 hours during site measurement work.
Auto triangular wave/step wave signal output.
It can store 8 sets of measurement and output data, and recall it to display. All the setting value and the function in the last operation can be saved automatically after power-off.
The screen shows the connection diagram of probes and plugs to avoid wrong operation. It has backlight.
The output has manual/auto step and slope output function. It can arbitrarily set the value of 0%, 25%, 100% in the range of signal output to test the response speed of transmitter.
Application field: measurement and calibration of instruments, maintenance and overhaul of temperature instruments, automatically maintenance and overhaul, project construction debugging, detection and diagnosis of control system signal source, configuration of site instrument repairmen room, matching of the thermal engineering laboratory in electric power industry.
