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.
