Mobile Gas Detector

The handheld gas detector is good for monitoring and showing concentration of gases simultaneously. The testing is applied for petroleum, chemical, fire, electricity, metallurgy, pharmaceutical, gas, mines, food, warehouse, storage, transportation and other industries and Labs.


Handheld multi gases detector is highly accuracy and intrinsically safety. The advanced models for detecting gases and a cost-effective, mobile alternative to bench top analyzers. Is is able to set alarm points, if concentration exceed or less than preset alarm point, this device will warn sound and light alarms. It is provided all of advantaged newest technology give simple and fast operation. The multi gas detector is the ideal analyzer for sample testing, requiring only a minimal amount of sample gases to be detected that including measurement internal pressure of gas. It is equipped high-capacity chip, 4 layers PCB board and SETL and TWA alarm conveniently provide visual and audible alarm. The LCD large screen display with Real time of target gas concentration, clock and status of battery. The rechargeable battery help to reduce damage from power replacement and low battery icon make continuing detecting at site via charging.
