The AVG2 Digital Vacuum Gauge Head from Fieldpiece Instruments offers an easy, accurate method for evacuating moisture from refrigerant lines. Use the AVG2 with most multimeters to display pressure in microns of mercury from 50 to 2000 with resolution to 1 micron. The AVG2 quickly reacts to any pressure changes, allowing technicians to see drops and spikes of pressure in real-time. The STABLE LED indicates when pressure is no longer dropping. The "T" can be removed for easy cleaning. www.fieldpiece.com. — Fieldpiece Instruments
