ZRD2100 Handheld Remote Laser Methane Detector

ZRD2100 Remote Methane Leak Detector uses international advanced tunable diode laser absorption spectroscopy technology (TDLAS),which can detect methane gas within 100 meters distance. It is quite small and light, with high speed and sensitivity measurement and detection for methane and other gases containing methane, could easily detection methane anywhere in an Easy and Accurate way. Support OEM/ODM service.


ZRD2100 Handheld Remote Laser Methane Detector

ZRD2100 Remote Methane Leak Detector uses international advanced tunable diode laser absorption spectroscopy technology (TDLAS), the detection distance and accuracy of the detector could be reach 100 meters, which is capable of remotely detection methane and other gases containing methane (such as natural gas, biogas or similar ).  It could fast detect gas leaks or accumulated methane gas from a remote place by pointing a laser beam at the target.

Principle of measurement:

Unlike traditional portable detectors, this Remote Methane Leak Detector does not need to place the probe in a gas-filled environment. Instead, the device emits a laser beam. The laser passes through the pipe or the space above the facility and hits the object at the other end. Reflected back to the receiver, and then converted into electrical signals, these signals are used to analyze the concentration of methane, the unit is ppm﹒m. By using WMS technology, the ZRD2100 Remote Methane Leak Detector can achieve extremely high detection accuracy. The light at this wavelength is only absorbed by methane, so it only reacts to methane and is not affected by other gases, which greatly improves the accuracy of detection.  Using the Remote Methane Leak Detector, the operator does not need to be in a dangerous environment, which not only protects the safety of the inspector, but also can inspect the overhead pipeline from a long distance, which improves the inspection efficiency. The detection reading is the product of the concentration of the laser passing through the methane gas mass and the thickness of the gas mass in ppm﹒m, as shown below:
