Brief Introduction
PGas-41 portable multiple gas detector can detect the content of four kinds of gases(oxygen, carbon monoxide, hydrogen sulfide and methane) at the same time and display the concentration .It will alarm immediately once the concentration of gas reaches or exceeds the preset alarm point.
Main Features
u Real-time detection of oxygen, carbon monoxide, hydrogen sulfide and methane
u True-color lattice TFT screen display
u Setting upper/lower alarm points, STEL and TWA is also inclusive for carbon monoxide and hydrogen sulfide gases
u Automatic battery detection and undervoltage indication.
u Alarm with LED, buzzer, earphone(optional) and vibration
u Setting brightness of back light according to practical need to save power
u Storage of historical data and alarm events
u NDIR printer can print real-time concentration data(optional)
u Gas pump realizes detection by pumping(optional)
u Calibration and set of detector through PC
