MH-741A Infrared CH4 Gas Sensor
- Product SKU: INFMH-741A
- Category:Best selling products,Home page,Winsen Sensors
Application:Widely used for industrial field instrumentation, industrial-process control and safety protection.
Feature:High sensitivity, high resolution,low power consumption,Output method: IIC, analog voltage signal, etc.
Production Description:
MH-741A is a universal type intelligent sensor to detect CH4 gas,taking advantage of non-dispersive infrared (NDIR) principle. With high selectivity, no oxygen dependence, high performance and long lifespan features, MH-741A also has built-in temperature compensation feature. MH-741A is a compact and high-performance sensor based on infrared absorption of gas detection technology, micro-machining and sophisticated circuit design.
Feature:
- High sensitivity, high resolution, low power consumption
- Output method: IIC, analog voltage signal, etc.
- Quick response
- Temperature compensation, excellent linear output
- Excellent stability, Long lifespan
- Anti-poisons, anti-vapor interference
- Detect combustible gas concentration matching with flame-proof marked detector in area 1&2 explosive environments which mix of ⅡA, ⅡB, ⅡC and T1-T6 flammable gases, vapors and air.
Application:
Widely used for industrial field instrumentation, industrial-process control and safety protection.
