QB200N series gas detector

QB200N series gas detector is a fixed type instrument that can continuously detect the gas concentration in the working environment. The detector is a natural diffusion sampling method to detect the gas concentration, the sensor has good sensitivity and excellent repeatability; LED digital display suitable for factory applications to show the concentration of the leaking gas in real time, more than the preset alarm point immediately start the sound and light alarm or drive the exhaust system; international standard (4 ~ 20) mA signal can be directly connected to the factory DCS system; the instrument uses embedded micro-control technology, easy to operate, functional and easy to use. The instrument adopts embedded micro-control technology, simple operation, complete functions and high reliability.

♦ The instrument adopts low power consumption embedded micro-controller.
