Top 10 Auto Vacuum Gauge Tester

Check fuel pump suction or pressure. Tests settings of the carburetor. Checks for sticking valves, valve timing, and burnt valves or insufficient valve tappet clearance. Detect weak valve springs, worn valve stern guides, or leaking head gasket. Quick, accurate testing for a variety of applications.

An inexpensive utility gauge for the broad commercial and industrial markets. Suitable for air, water, oil, gas or any other media not corrosive to brass.

As a professional technician the assurance of a deep vacuum on a system is imperative. The main problem with many small handheld units is their inaccuracy and durability. Although the thermocouple sensor has been proven to be much more accurate and durable than the thermistor type, the problem has been the inconvenience of a cumbersome tabletop unit.

Mastercool’s hand held unit uses thermocouple technology. This vacuum gauge has been designed with the technician’s field environment in mind, allowing for self-calibration and a sensor that will not be damaged by small mists of oil. The Mastercool unit allows for a target vacuum range to be programmed with a light sensor indicator. Now you have the freedom to continue with your other work and come back to the system once you see the indicator light signaling your target vacuum.
