The 14830A Thermistor Vacuum Gauge has been designed to use with high vacuum pumps to accurately measure vacuum level during evacuation of A/C and refrigeration systems. This unit indicates precisely when the system is free of air and water, eliminating guesswork and saving valuable service time. It can also be used to check for leaks without precharging; if the system holds a vacuum, it is leak-free. Battery and A/C powered and self-contained in a durable carrying case, the 14830A is easy to use and transport. The sensor is built into the unit and connected to the system through a fitting on the front panel. A 24” Premium Refrigerant Charging Hose is included for connecting the thermistor and the system. The hose is stored in a recessed area of the case.

Save service time by using a vacuum valve assembly with your vacuum pump! The 13047A valve assembly connects all pieces of equipment necessary for evacuating and monitoring vacuum—vacuum pump, manifold, and thermistor vacuum gauge.
