TDLS (Tunable Diode Laser Spectrometry) gas analysis modules are a new generation of ultra-high precision gas detection products which are suitable for coal mine, chemical industry and other industries. Based on the principle of laser spectral absorption, the modules have
- High measurement accuracy
- Wide range
- Quick response time
- Internal temperature compensation and cross interference compensation
- Good stability
- Long service life.
These modules are capable of continuous detection of the gas concentration. The modules have RS485 communication interface and use Modbus communication protocol.
