One. Introduction
    

     KE5209 thermal instrument calibrator, is the company introduced a portable high-precision measuring instruments. Using high quality components and automated testing techniques, the use of adjuvant multi-CPU processing and made to ensure the accuracy and reliability, small size, light weight, AC and DC characteristics.

     The instrument has six and a half, and DMM source DC input and output functions, including voltage, current, and output of different measurement range.

     Adoption of international temperature scale, to measure B, E, J, K, N, R, S, T and other potential eight thermocouple and temperature, can simulate the output of the corresponding temperature, electrical

Potential. Can 4 ~ 20mA, 0 ~ 10 mA current output pressure transmitter or 0 ~ 10V, 0 ~ 5V voltage output pressure transmitter for measurement and analog output,

Instrument can measure their own temperature and the cold side cold junction compensation automatically.

     Can be used as precision measurement and calibration instruments, with the potentiometer, precision millivolt table, precision current meter, and the cold end of thermoelectric thermometers and other equipment

Even search indexing spreadsheet functions. Can be widely used in petroleum, chemical, metallurgical, power, measurement, automation and other industrial and mining sector and research institutes.
