The CJZ6ZW | CJZ6ZW/150 Wireless Borehole Confluence Pipe Laser Gas Comprehensive Parameter Measuring Instrument is designed in accordance with the “Coal and Gas Outburst Prevention Regulations” (2019), Article 47: “When pre-draining coal seam gas, the extraction time of each borehole should be recorded, and the concentration, negative pressure, flow rate, temperature, and carbon monoxide of the borehole should be periodically measured.” This instrument employs advanced measurement and gas concentration detection technology, making it suitable for online monitoring of gas boreholes, drilling sites, or individual units.

– The instrument can simultaneously display instantaneous values of parameters such as flow velocity, flow rate, methane concentration, pressure, and temperature on a single screen, as well as cumulative mixed values and pure cumulative values over a certain period.

– The instrument’s low flow velocity measurement limit allows it to be used for gas extraction monitoring of both individual boreholes and confluence pipelines at drilling sites.

– Methane concentration is measured using laser technology, which is not affected by water vapor or other impurity gases. The measurement includes pressure compensation functionality, allowing accurate methane concentration measurements in high negative pressure environments.

– The instrument is equipped with a backup power supply, enabling normal measurements during unexpected power outages.

– The instrument supports RS485 and wireless communication functions, allowing the establishment of a wireless self-organizing network.

– Explosion-proof type: Intrinsically safe for mining (Explosion-proof mark: Exia1Ma).

– Protection level: IP65.
