decomposed gas analyser

purity meter and leak detector are calibrated by the platform where the standard gas required by the calibration is composed through a multi-gas dynamic supplier

controlled by computer. The humidity generator is controlled to prepare the constant humidity gas which is used to calibrate the micro-water detector in SF

gas. An air quality monitoring system is used to monitor the real environment and if any leakage is detected

acoustic and optic alarms will be raised and air circulation fan is switched on to ensure a safe environment. The developed platform can be used to carry out multi-parameter calibration of SF
