RD-3
RD-3 Handheld Hydrogen Leak Detector
Handheld hydrogen leak detector (RD-3) adopts dual sensor detection mode, both "small range high sensitivity" and "large range high precision" dual range leak detection function, and has real-time display of measurement results and parameter storage functions. When the gas concentration in the measured environment reaches or exceeds the preset alarm limit, it will alarm immediately. The instrument can be used in hydrogen production station, hydrogenation station, fuel cell system production workshop, hydrogen energy bus company, hydrogen testing laboratory and other occasions.
Feature
▪ 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 within 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 conditions and can be eliminated manually
▪ Support for user password modifications for sake of user operation protection
