Product Details
MH-712B Infrared CO2 Gas Sensor
Description:
MH-712B is a universal type intelligent sensor to detect CO2 in air
taking advantages of non-dispersive infrared (NDIR) principle. With
good selectivity, no oxygen dependence, stable performance and long
lifespan features, MH-712B also has built-in temperature
compensation feature. It is a compact and high-performance sensor
based on infrared absorption of gas detection technology,
micro-machining and sophisticated circuit design.
Application:
Widely used for industrial field instrumentation,
industrial-process control and safety protection
Features:
- High Sensitivity and resolution, low power consumption, fast
response
- Output method: UART, analog voltage output signal, etc.
- Temperature compensation, excellent linear output
- Good stability
- Long lifespan
- Anti-poisons, anti-vapor interference
