Product details
Intelligent digital inspection instrumentThe meter adopts a dedicated integrated instrument chip, and the measurement input and transmission output use digital calibration and self calibration technology, ensuring accurate and stable measurement, eliminating measurement errors caused by temperature drift and time drift. This series of instruments adopts surface mount technology and is designed with multiple protection and isolation measures. It has passed EMC electromagnetic compatibility testing and has strong anti-interference ability, high reliability, and high cost-effectiveness.
Intelligent digital inspection instrumentThe meter has programmable functions for multiple types of inputs, and can be matched with different input signals (thermocouple/thermistor/linear voltage/linear current/linear resistance/frequency, etc.). At the same time, the display range, alarm control, etc. can be set by the user on site, and can be used in conjunction with various sensors and transmitters to achieve measurement, display, adjustment, alarm control, data acquisition, and recording of physical quantities such as temperature, pressure, liquid level, capacity, and force. Its application range is very wide.
Intelligent digital display instrumentThe measurement value (PV) and channel value (CH) are displayed using dual row four position LEDs, and alarm display of each channel measurement value is performed using dual color light-emitting tubes. It also has zero and full correction, cold end compensation, digital filtering, communication interface, multiple alarm methods, and can be equipped with relay alarm output, transmission output, or standard communication interface (RS485 or RS232C) output.
