High precision hydrogen concentration detector and hydrogen leak alarm

Note: This price is for display only, actual prices are subject to the quotation!!

The QB2000N module combustible gas detection transmitter detects gas concentration through natural diffusion and uses imported catalytic combustion sensors, which have good sensitivity and excellent repeatability; LCD or LED digital displays suitable for factory applications display the concentration value of leaked gas in real time, and immediately activate the sound and light alarm signal or drive the exhaust system when the preset alarm point is exceeded; The international standard 4-20mA signal can be directly connected to the factory DCS system, and the RS485 digital signal is connected to the factory upper computer; The instrument adopts embedded microcontroller technology, with simple operation, complete functions, high reliability, and reliable overall performance.

QB2000NHigh precision hydrogen concentration detector and hydrogen leak alarmIt is a fixed instrument that can continuously detect the concentration of flammable gases in the working environment.

The QB2000N high-precision hydrogen concentration detector is easy to install and maintain, and can measure a wide range of gas types, meeting the requirements of high reliability and stable operation of equipment and diverse gas types for industrial site safety monitoring and measurement; It has been widely used in industries such as petroleum, chemical, metallurgy, refining, gas transmission and distribution, biomedicine, and water treatment.

The QB2000N high-precision hydrogen leak alarm consists of a cast aluminum housing, a stainless steel sensor breathing device, a sensor module, a display module, a main control module, a digital communication module, a dust cover, and a calibration cover.

QB2000N high-precision hydrogen concentration detector:

1、 The catering industry, boiler rooms, gas stations, and gas stations all detect combustible gases (combustible gases - methane, liquefied gas - propane, gasoline, diesel);

2、 Wastewater treatment plants, sludge treatment plants, detecting hydrogen sulfide (H2S), ammonia (NH3), and combustible gases (CH4);

3、 Water plant testing (CL2), chlorine dioxide (CLO2);

4、 Detecting carbon monoxide (CO) and combustible gases (CH4, H2) in the steel and metallurgical industry;

5、 Paint factories (workshops, warehouses) detect flammable gases (benzene, toluene, etc.);

6、 Spray painting factories and paint baking rooms usually use high-temperature combustible gas detectors to detect volatile gases such as benzene and toluene;

What industries can combustible gas detectors be applied to?

7、 Petroleum and chemical enterprises are relatively complex, with combustible gases and uncertain types of toxic gases;

8、 Non coal mines (such as non-ferrous metal mines, iron mines, molybdenum mines, etc.) generally use portable four in one or detect carbon monoxide (CO), nitric oxide (NO), oxygen (O2);

9、 General detection of combustible gases (methane CH4), hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2), etc. in electricity, communication, etc., with fixed and portable four in one;

10、 On ships and shipyards, combustible gases and oxygen are generally detected;

QB10N hydrogen combustible/toxic gas alarm is widely used in the catering industry, boiler rooms, gas stations, gas stations, sewage treatment plants, sludge treatment plants, steel metallurgy, petroleum, chemical industry, paint factories (workshops, warehouses), spray painting plants, paint baking rooms, power, and communication industries.
