Please see below for a description of several of the items included in this package.

The single ball valve manifold has a large 3 1/8″ gauge (PSI/°F) with an easy-to-read temperature scale and includes a 2-mm thermoplastic service hose with 1/4″ SAE female straight fittings with a depressor for maximum precision on small capacity systems.

The Intellasense III combustible gas leak detector has a low-power metal oxide gas sensor with superior performance properties such as lower current consumption and sensor longevity. The sensor is characterized by high sensitivity and fast response upon detecting the presence of extremely small levels of chlorofluorocarbon gases. In addition, a powerful microprocessor was integrated into the design that automatically selects the best operating condition for the sensor to ensure optimum performance throughout its life.         

Mastercool’s high-precision charging scale accurately measures small cans of refrigerant (sold separately) for charging systems that need a precise charge. Small cans of refrigerant attach directly to the scale for ease of use.

The “Black Series” spark-free single-stage 6 cfm vacuum pump is durable and time-tested to stand up to the most grueling conditions and will provide years of reliable service. This vacuum pump provides the power and mobility necessary for a wide variety of applications.

The Mini Twin Turbo combustible-gas recovery machine is approved for air conditioning refrigerants including A2L and A3 flammable refrigerants. Equipped with a high-quality twin-piston compressor this unit has been designed to work in all applications. Whether you find yourself up a ladder, in a crawl space or just not looking forward to lugging around a heavy piece of equipment, this is the right machine for you. Best of all, this machine has been constructed with the safest spark-free components allowing for use with all combustible gases.

Hydrocarbon refrigerants are natural, non-toxic, and have no ozone-depleting properties. They are more efficient than the HFC refrigerants that they replace. The improved system efficiency they produce reduces energy usage and life cycle costs.
