GAOTek Hydrogen Fluoride Gas Concentration Detector

Description Features LCD dot matrix display, the gas type, unit, concentration, local time, can be shown on the screen. Support Chinese and English operation, easy to shift. The gas concentration unit PPM and mg/m3 can be shifted quickly. Explosion-proof certification, explosion-proof grade: ExiaⅡ Monitor the HF gas concentration in environment and enclosed space and alarm. With Self-calibration and zero calibration functions, high precision HF gas detector. One press to restore factory setting, free from the bother of mis-operation. With temperature and pressure compensation, to realize gas concentration compensation under conditions of different temperatures or pressures. Two stages alarm with sound and light, alarm point is settable. Rechargeable lithium polymer battery of large capacity.   Technical Specifications Gas Detected HF, hydrogen fluoride Detection principle Electrochemistry, use imported high precision HF gas sensor Sampling Method Pumping suction, flow rate can up to 1L/min, ten grades of pumping suction for selection. Measure Range 0 ppm to10 ppm,0 ppm to 20 ppm,0 ppm to 50 ppm,0 ppm to 100ppm Resolution 0.01ppm, 0.1ppm, 1ppm Precision ≤± 5% F.S.
