QB500N Series Standalone Gas Detector

QB500N industrial and commercial point gas detector (hereinafter referred to as the detector) is a fixed instrument that can continuously detect gas concentration in the working environment. The detector detects gas concentration by natural diffusion and adopts imported catalytic combustion sensor, which has good sensitivity and excellent repeatability; the LED digital display suitable for factory application displays the concentration value of leaked gas in real time, and immediately activates the sound and light alarm or drives the exhaust system or drives the 220V AC solenoid valve or 24V DC solenoid valve when it exceeds the preset alarm point, with zero-crossing shutdown function; it can be connected to the smart cloud platform through the optional NB-IOT module; the instrument adopts embedded micro-control technology, simple operation, complete functions, high reliability, stable and reliable performance of the whole machine.

● The instrument uses an embedded microcontroller

● LED digital tube display

● Safe infrared remote control operation without opening the cover

● Important operations require password verification to effectively prevent misoperation

● Integrated sound and light alarm, clearer alarm action

● Solenoid valve AC solenoid valve or DC solenoid valve can be configured by yourself in the menu function
