Description
– Detection of all the HCFC and HFC refrigerants
– Detection of mixtures 5% hydrogen – 95% nitrogen (Nidron 5…)
– Heated diode sensor
– 3 modes of sensitivity (high, low and normal)
– Manual and automatic autozero
REGLEMENTATIONS:
The refrigerant gas detector complied with the EN 14624 standard that determines the following points :
– Minimum threshold of sensitivity :
Fixed : < 1 g / year at 3 mm
In moving air : 2 g / year, 2 cm / s at 3 mm
– Minimum time of detection (1 g / year) : 1 second
– Autozero : 2 seconds
– Recuperation time after exposition : from 1 to 10 seconds (depending on detection level and threshold of sensitivity)
