  • Gas Drainage Multi Parameters Detector - China

    price: 3.00 Dollar US$

    Model: CJZ18W
    Description: CJZ18W Gas Drainage Multi-parameters Detector
    MA: MFA150197 (National safety sign for coal mining products)
    KA: KFA150024 (National safety sign for mining products)
    ExibI Mb: 320150856 (Intrinsic safe and explosion-proof products certificate) Introduction: It’s a comprehensive instrument to detect parameters of pipelines (main and branch pipelines) and gas drainage pump. It measures and displays CH4/CO2/CO/O2 concentration inside pipeline and pipeline’s negative pressure, differential pressure, absolute pressure. It can also measure pump’s inlet/outlet absolute pressure, rotational speed, voltage, current, power, efficiency. For water ring vacuum pump, instrument can measure its water pressure, inlet water temperature, outgassing temperature and pump house’s temperature and humidity. Features:
    1. Tailor-made flow detecting device.
    2. Imported non-dispersive infrared methane and CO2 sensor.
    3. Owns memory function in case of power interruption. 4. Data storage.
    5. FATFS files storage. Technology Parameters:
