Cliplight Mfg., a leading HVAC/R tool, leak detection and refrigeration sealant manufacturer, has introduced the TIGAR Mic, a mechanical analog display micron vacuum gauge kit that increases vacuum measurement accuracy because it connects directly to a refrigeration system’s low-side pressure valve without hoses. 

The patent-pending TIGAR (Total Integrated Gauge Analog Response) Mic eliminates the need for rubber connection hoses, which according to ASHRAE (American Society of Heating Refrigerating & Air Conditioning Engineers) can skew measurement accuracy when gauging a system’s vacuum in microns. Instead, the TIGAR Mic gauge and evacuation pump both connect directly into one of two included Cliplight Valve Core Remover (VCR) tools.

The TIGAR Mic Kit’s VCR’s have accessible 65-degree-angle side ports combined with smooth surface discharge (no internal threads), which allows 33-percent faster refrigerant recovery. The VCR’s require no special tools or charging fittings and fit all refrigeration systems except for some selected R-410a equipment.
