SGJ100(A) Digital Calibration Device for Optical Interference Methane Detector
SGJ100(A) digital calibration device for optical interference methane detector (hereinafter referred to as calibration device) adopts rotary piston pressure pump and precision digital pressure gauge, which has the characteristics of stable pressure regulation and high test accuracy. It has upper limit alarm function, the display is clear and intuitive, the operation is convenient and simple; it has the advantages of high precision, corrosion resistance, impact resistance, vibration resistance, anti-electromagnetic and radio frequency interference technology, and high stability.
The calibration device is mainly used to calibrate the basic error and gas tightness of the optical interference methane detector with measuring range (0-10) % CH4 and (0-100) % CH4, and also to provide the standard pressure source for various micro-pressure (0-60) kPa measuring instruments.
