Sell standalone Hydrogen Sulfur alarm detector

Description

Standalone oxygen alarm detector is a fixed type detector that can be used continuously in operation environment to detect the density of combustion gas, oxygen, or poisonous gas. The alarm detector adopts natural diffusion to detect gas, and it use the imported electric chemical sensor (catalytic combustion type for flammable gas) which has excellent sensibility and receptivity; big LCD displays the density of the leakage gas real time and if the density exceed the preset alarm point it will start the acoustic-optical alarm or the exhaust system;  ***0mA can be directly connected into the factory DCS system, RS**5 digital signal is connected with factory’s principle computer; the device adopts embedded micro controlling technique, the Chinese menu is easy to operate and the function is complete and reliable. The performance of the whole device is among the best ones in China.
Characteristics:
the device adopts advanced *6 digit ultra-low power consumption embedded micro controller.
**8**4 dot matrix ultra-large liquid-crystal display
user can set the alarm point by themselves
Displaying the time of fist alarm
