TDLS/TDLAS [Tunable Diode Laser (Absorption) 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.
|Methane & Ethane Detector PD358
|Natural Gas consists primarily of Methane and Ethane. If you want to detect the presence of natural gas without false readings detecting both gases is critical. Methane by itself is everywhere.

Handheld Methane (CH4) Detector Sensors
For applications where a portable Methane sensor is important there are a flashlight size and a handheld sensor.
|Mini Gas Flashlight Methane (CH4) Detector L10M
|Handheld Methane (CH4) Detector C10X
Lasers for Gas Sensing
These lasers have wavelengths that are matched to the absorption band of the gas indicated. Because of this they are very accurate and reliable.
|760nm SM VCSEL (Laser) for O2 Sensing
The larger TDLS (TDLAS) modules are capable of continuous detection of the gas concentration. Their response time is shorter because the sample gas is filtered and pumped through the module. The modules have RS485 communication interface and use Modbus communication protocol. Gases measured using these modules include:
