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.
Precision TDLAS Gas Analyzers
The Beamonics precision TDLAS Gas Analyzers are high-performance turnkey solution based on tunable diode laser absorption spectroscopy (TDLAS) for gas analysis. The analyzers are designed with user- and integration-friendliness in mind, suitable for both industrial settings with PLC systems and research laboratories, where raw and/or processed data can easily be exported and visualized for post-processing in third-party tools.
The robust and established TDLAS technology provides fast (100 μs) and highly sensitive (PPB-level) gas analysis.
The TDLAS technology is also inherently self-referencing and calibration-free, requiring little to no maintenance.
The analyzer can measure many common gases found in the industry and laboratories, including greenhouse gases such as methane (CH4). Other commonly measured gases include O2, CO2, CO, N₂₂O, NH₃, NOx, HF, H2S and HCl, as well as hydrocarbons.
The highly energy-efficient designs allow the BeamStack, BeamCell and BeamSight Modules to run for hours on batteries, making them well-suited for mobile analyzer solutions at locations where there is no access to external power.
The calibration-free gas analyzer system is highly durable for use in heavy industries and extremely robust in harsh environments.

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.
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.

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:
DOAS/ NDUV is used for gases where water (H2O) interferes with the reading because the absorption bands are similar.
