Precision You Can Hear, See, and Trust!

“ Works like a charm. Easy to use. Requires 3 AA batteries but that is minor, and did everything I wished for when it came to putting a system into a vacuum.” - Maureen K.

Why Get Our Digital Vacuum Gauge?

✅Fast, Fine-Tuned Measurement: Under-evacuation in an HVAC system can leave behind moisture and air, which leads to acid formation and compressor failure over time. On the other hand, over-evacuation wastes time, wears out vacuum pumps faster, and offers no added benefit once deep vacuum levels are already achieved.This gauge starts with 0.5 micron resolution at 0–200 microns, giving pros the data they need to prevent under- or over-evacuation. It also updates every 0.5 seconds to keep results live and reliable. It can measure from 0 to 12,000 microns.

✅Clear Readings in Any Light: It uses a bright, backlit LCD that’s easy to read in garages, mechanical rooms, or outdoor service sites. It also displays seven unit types, perfect for global teams or specialized applications.

✅Hands-Free Setup and Alerts: No need to babysit the gauge. Use the built-in hook to hang it, then rely on the 87 dB alarm to notify you when your desired vacuum level is reached. Visual alerts help even in noisy environments. With up to 600 hours of battery life and a serviceable cleaning port, it is also built for long-term field use. 

📓FREQUENTLY ASKED QUESTIONS
