Introduction:

HK-7100A/HK-7101 combustible gas detector is a kind of instrument independently researched and developed by our company to monitor the concentration of combustible gas in the field environment in the control room. It can be widely used in petrochemical, oil and gas storage and transportation, chemical industry, oil depot , Liquefied gas stations, gas-fired boiler rooms and other areas where flammable and explosive hazardous gases exist.

Features:

1. Five detection principles cover almost all flammable and toxic gases;

2. Five kinds of detection principle detector host universal, hundreds of gas and range of smart sensors are fully compatible, fully interchangeable;

3. It is very convenient to replace the pluggable smart sensor, the host automatically recognizes the measuring principle of the sensor, the type of gas measured, the range, etc.;

4. The sensor supports hot-plugging, plug and play, sensor failure self-diagnosis;

5. Advanced 32-bit embedded microcontroller technology, data processing and rapid;

6. Can use centralized bus power supply, can also use independent area power supply, the choice is more convenient;

7. Wide temperature, high brightness OLED display, easy reading in direct sunlight and dark environment, adapt to harsh temperature and lighting environment;

8. Chinese and English bilingual menu, friendly user interface;

9. Unique magnetic pen and infrared remote control operating mode (infrared remote control is optional), user-friendly operation;

10. The advanced SMT patch process reduces the volume of the product and improves the reliability of the product.
