BGQ-1 gas meter calibrator test instrumentation products Name: laser pointing device Model: YHJ-500 Manufacturers: Shandong Coal Price: Negotiable Transportation: Express Keywords: instrument calibrator gas portable gas meter calibrator Sales calibrator instrument calibrator BGQ-1 portable gas meter calibrator is mainly used to calibrate the coal mine methane sensors, oxygen sensors, carbon monoxide sensors, power meter and other fixed using methane gas detection instrumentation; also be used for a variety of ground calibration gas detection alarm, analyzer. Is the best choice for mine ventilation area, security metering station (Lab), and other units. The main technical parameters: Measuring range: 60 ~ 600ml / min, 0 ~ 10MPa uncertainty: 4%, 2.5% standard gas Capacity: 140L Weight: 5kg works: calibrator pumping and aeration pump to gas source by available. Mouth breathing with the mouth with the three-way interface with the calibrator is connected to a plug, air or gas inside the respirator through the pump inlet / outlet port into the gas path after switching to a pneumatic switch, the switch after the gas into the pump interface and thus covered by mouth with a tee respirator hose directly into the low pressure system. By converting the operation of the valve to change the air flow, into the respiratory system in order to achieve aeration and pumping. Basic configuration: two bottles of 0.2L cylinder, a valve, a flow meter, 0.5 m hose, a leather bag. Optional: various concentrations of calibration gas, special purpose valve (such as hydrogen sulfide corrosion resistant valve needed) Warning: This product is for use in ground-ventilated place!
