The detector will measure the total methane content in volume. The internal processor calculates the volume ratios of gas. A quality laser portable methane detector will track all those dangers. Furthermore, alarms will indicate if unsafe conditions are present quickly.

• ppm.m

Ppm.m units represent path-integrated measurements of methane gas. You can use this measurement for determining total gas presence. This can help assess the risk levels within larger areas. Longer paths need this type of measurement for total assessment.

So, the internal detector calculates the overall exposure using math. The internal processor will handle all of the complex math. The display should present a total column density of gas. Finally, data logging systems will record all of those historical readings.

How Does Laser Technology Improve Methane Detection?

• TDLAS Principle

The TDLAS Principle also known as Tunable Diode Laser Absorption Spectroscopy operates with exceptional results. The advanced TDLAS technology provides you with unique gas detection capabilities. The internal laser emits a very narrow bandwidth of light.

Methane will absorb this specific wavelength of the emitted light. Other gases present will not cause any reading interference there. The detector will measure the light reduction caused by gas. A high-quality l methane detection system offers unmatched gas specificity. The internal photodiode detects even those very faint light signals.

• Wavelength Specificity

The wavelength-specific feature helps produce accurate measurements which prevents incorrect readings from occurring. With this latest development you easily avoid unnecessary wrong readings. As methane will only absorb light at around 1.65 micrometers.

Other various gases do not interfere at that same wavelength. The internal laser targets only one particular type of molecule. The detector will ignore all other present gas compounds. A carefully chosen laser portable methane detector gives you precision. The internal sensor will only detect that pure signal.

• Single-Path Measurement

Single-Path measurement simplifies the optical design for improved reliability here. You will certainly enhance reliability and also speed with this, as light will travel directly to the sensor from the source. There are very few optical components needed for this design.

Fewer parts inside mean fewer potential points of failure. The detector will respond very quickly to gas presence. The internal processor requires very minimal data correction. And, the optical beam alignment is incredibly simple with this.

• Optical Absorption

Optical absorption principles underpin accurate and reliable methane gas measurements. You get very accurate gas measurements by using absorption principles. Methane molecules absorb the special laser’s emitted infrared light energy. More gas present means less total light will reach sensor.

The internal detector accurately measures this light reduction carefully. A laser portable methane detector employs the basic laws of physics. Periodic calibration will ensure your perfect measurement accuracy.
