Robinair 14777 Compact Electronic Vacuum Gauge.
Robinair's 14777 electronic vacuum gauge is just 2 1/2" x 3" in size, but accurate enough to clearly indicate when the system is free from moisture and ready for recharging.
Specifically designed for use with a high vacuum pump, the 14777 measures to 10 microns. The digital display reads in ranges beginning with 10,000 microns (just push a button to select Torr or kPa readings). As the vacuum pump continues to pull down, the instrument registers in smaller segments - from 1000s of microns to segments of 500s to 50s. The ultimate reading is 10 microns.
Clearly Shows Vacuum Level - The display is an easy-to-read LCD type with readout showing the current vacuum level. It also indicates the unit of measurement, so there's no guessing or confusion.
6' Lead for Service Flexibility - The pressure transducer measuring vacuum level is attached to a 6' long lead that plugs into the instrument. You can hang the gauge in a location that's convenient for you to monitor vacuum level. Because the transducer with lead is removable, it can be easily replaced, if necessary.
Hangs Up During Service - Use the heavy duty magnetic strip on the back of the unit to attach to the A/C or refrigeration unit. You can position the 14777 where it's easy to read the LCD.
