GQH500 hydrogen sensors Lu Heng Electric our core values: committed to making the most extensive customer enjoy the highest quality products and services, customers become the most trusted partner to expand Industry, China's electrical industry model. GQH500 hydrogen sensor is to measure the change in the value of the hydrogen content of the few romantic instrument, with local display the value of the hydrogen content, overrun sound and light alarm and power-off function. And automatically mine hydrogen into a standard electrical signal transmission to the associated equipment. After the online test can be used with all types of domestic monitoring and control system and power meter, power meter methane supporting wind power atresia; for there is danger of spontaneous combustion of coal miners working underground point hydrogen content of surveillance and monitoring. GQH500 scope and characteristics of hydrogen sensors GQH500 hydrogen sensor with stable, long life, etc., 4 LED digital display, intrinsically safe circuits, intelligent chip control, infrared remote calibration, intrinsically safe circuits, a variety of signal output format can be and supporting the use of various monitoring systems. Especially for mine cavern charging hydrogen concentration detected continuously. Standard three-wire mode operation (2-wire power supply, a line signal return). Technical indicators measuring range: 0ppm ~ 500ppm output signal: 200Hz ~ 1000Hz Display: four red LED display Operating voltage: 9V ~ 24V Dc Working current: ≤40mA proof type: Exib I Our values: customer first, teamwork, professional focus, innovation, positive action, forever young, brave and bare our team: integrity as the foundation to a passion for dynamic, hard work is the wisdom of a professional core, innovation-driven
