RD-3 handheld hydrogen eak detector uses two sensors for detection,supports small-range high-sensitivity leak detection and large-range high-accuracy leak detection and has functions including real-time display of the measured results,parameter storage,etc. It alarms when the gas concentration in the detected environment is equal to or higher than the set alarm limit.

Main Features

▶ Automatic zero correction

▶ Peak detection

▶ Data hold

▶ Quick response,and quick return to zero

▶ Power supply by a large-capacity lithium battery,battery level detection,and undervoltage prompt

▶ Two sensors which can switch automatically to detect hydrogen leakage of the ppm level or with in the minimum explosion limit

▶ Segment code LCD,and auxiliary alarm threshold LED(10ppm,100ppm,1000ppm,and 1%vol)

▶ Audible and visual alarms that have different frequencies in different alarm condition sand can be eliminated manually

▶ Support for user password modifications for sake of user operation protection
