Model Number: OC-B10-methane Brand Name: Oceanus Key Specifications/Special Features: Description:Laser methane remote gas detectorB10 with the TDLStechnology,it can quickly and efficiently detects methane leaks up to 30 meters always, laser gas remote detector makes the on foot inspection become more effective and accurate,besides,makes it possible to inspect the areas that hard to reach or impossible be reached, such as thebusy roadways,locked gates,pipes suspended under a bridge,indoor commercial pipingLaser remote gas detectorconsists of two interactive sub-systems, transceiver subsystem has two lasers:an infrared laser for gas detecting and a green/red spotter laser, infrared laser is non-visible and is continuously on while the laser gas remote detector’s measure button is pressed, green/red spotter laser is similar to those used for presentation pointers and is turned on by the operator pressing the Measure button,when the infrared laser is transmitted from the launch port and passes through gas, the methane absorbs a portion of the light,and then some of the laser light is reflected by a normal background such as brick,concrete,grass,to the detector,this reflected light is collected and converted to an electrical signal that carries the information, signal processing subsystem deduces the relative methane concentration that can be reported in ppm-m or % vol, gas concentration and distance detected will be displayed on the screen simultaneously, laser is selective to methane only,it will not false alarm on other gas,ashes,moistures,which improve the accuracy of the detecting without false detecting resultTechnical parameter:Detection method: tunable diode laser spectroscope (TDLS)Measuring gas: CH4 (NH3/HCL/C2H6/C3H8/C4-C6 optional )
