Portable NO2 Gas Detector LPSG-A21 is a fast response and high accuracy gas measurement device with 0 to 1000 ppm range. Its internal sampling pump with fast sampling speed and high flow rate, ensures the accurate response time of the detector. Portable nature, small size ait offers role in special high intensity engineering plastic housing, suitable for different kinds of situation and environment. The gas concentration unit ppm and mg/m3 can be shifted quickly and also the local time can be shown on the screen.
