Yellow Jacket 69047 EVac I Digital Vacuum Gauge — 0 to 25,000 Micron | HVAC/R
The Yellow Jacket 69047 EVac I is a compact, rugged digital vacuum gauge designed for HVAC/R technicians who need accurate, easy-to-read vacuum measurement during system evacuation. It measures 0 to 25,000 microns with 1-micron resolution and 5% accuracy (±5 microns), displays readings in five selectable units, and includes an automatic oil sensor to detect oil contamination in the vacuum line. Battery life is up to 300 hours on a single 9V battery.
The EVac I can be field calibrated without special equipment, and built-in memory retains all previous settings. At approximately the size of a manifold gauge, it is compact enough to carry on every job.
Important: System evacuation and refrigerant handling requires appropriate trade qualifications. Confirm licensing and compliance requirements with the relevant authority in your state or territory before undertaking refrigerant work.
