The Sauermann Si-RD3 refrigerant leak detector uncovers leads of most common refrigerant gases to a high degree of sensitivity, including all HCFC and HFC refrigerants, R1234yf, R1234ze, R290, R600a, and 5% hydrogen-95% nitrogen mixtures (Nidron 5 and Trace-A-Gas).

The Si-RD3 complies 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)

The detector is supplied with a verification certificate according to 2007-737 decree.
