Overview
NT-823D 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, NT-823D 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.
Key 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
Applications
Widely used for industrial field instrumentation, industrial-process control and safety protection
