CCT-6A Gas Chromatography Calibration Device

1、 Product Introduction:

CCT-6A typeGas chromatograph calibration deviceIt is a specialized calibration instrument designed according to the requirements of JJG700-2016<<Gas Chromatography>>calibration regulations, suitable for use in metrology departments. And automatically record and store measurement data. Can verify the temperature control stability, program temperature repeatability, noise, drift, attenuator error, and heating rate of the column box.

2、 Product features:

Gas chromatograph calibration deviceThe stable measurement of 5 1/2 precision voltage has been achieved, which is the core technology for 5A upgrade and replacement. It can be used in conjunction with platinum resistance thermometers to measure temperature. The calibration parameters of the thermometer and the calibration values of the instrument can be input, modified, and stored for a long time through system operation. The instrument is small in size, light in weight, easy to carry, and convenient to use, making it an ideal specialized instrument for calibration.
