portable multi-functional calibration instrument

Special Portable housing , convenient to carry , easy to operate, etal case ,durable and good intensity

JC-ZJF-5 portable multi-functional calibration instrument is the portable high precision measurement instrument from our company. It using high quality components and automation test process, using multi-CPU aided treatment, ensure high precision and reliability, has the characteristics of small volume, light weigth, ac and dc etc.

This instrument has six site dimidiate digital multimeter and signal source dc input and output function, include the different range’s measure and output of voltage and current.

Using international temperature scale, it can measure eight kinds of thermocouples’ potential and temperature of B, E, J, K, N, R, S, T, it can analog output corresponding temperature and potential. It can measurement and analog output of 4~20mA, 0~10mA current output type pressure transmitter or 0~10V, 0~5V voltage output type pressure transmitter, it can measurement the cold junction temperature of instrument itself and automatic cold junction compensation.

It can use as high precision measurement and calibration instrument, has the equipment of potentiometer, precision millivoltmeter, precision ammeter, cold junction thermometer, and the function of thermocouple indexing table for reference. It can widely used in industrial and mining department and scientific research unit such as petroleum, chemical metallurgical, elcetric, measurement, automation etc.
