The Multi-Gas LS-4 provides a useful reference against which an engineer can check the sensitivity of their leak detector at regular intervals during a leak detection job. This can help to quickly identify battery or sensor problems which can affect the performance of the detector.
When fitted to the outlet of a bulk refrigerant supply the Multi-Gas LS-4 will produce aflow of refrigerant at 5g/Yr. If a leak detector responds to the Multi-Gas LS-4 output then it can be considered sensitive enough for use under current F-Gas regulations(EN-14624).
The LS-4 is made from a stainless steel sinter leak element in a stainless steel bodyand a brass 1/4” SAE flare nut for easy use with standard refrigeration equipment.
The basic element is also available in expanded formats with gauges, reservoirs and certification.
