Portable Nitrogen N2 Gas Detector LNGD-A10 take sample by built-in pump and has measuring range of 0 to 100 % VOL, fast and accurate measurement. Features with stable flow pump, each flow pump is equipped in each independent module, pump flow is adjustable in ten steps, and flow range is up to 0 to 500 mL/min. It display multiple display modes selectable, multi-channel data mode, multi-curve mode, multi-channel data + multi-curve mode, single channel + single curve mode. Designed with 3.5-inch high-definition color screen, high resolution, wide viewing angle. The air supply system of up to three pumps can switch the pump arbitrarily, blocking the loss of the cross-gas to the relevant sensor and prolonging the service life of the sensor. It support gas concentration data display, gas concentration real-time curve display mode arbitrary switching.
