800 PSI Wireless Refrigeration Pressure Gauge with Bluetooth App
The Elitech PT-500Pro+ replaces mechanical manifold valves with a digital gauge that measures pressure and temperature. It supports 18 built-in refrigerants, expandable to 140+ via the Elitech Tools app with OTA firmware support.

Built for Daily HVAC/R Service
Digital pressure and temperature measurement with app connectivity — designed to replace mechanical manifold valves.
800 PSI Pressure Range
Measures -14.5 to 800 psi with ±0.5% FS accuracy — 60% more headroom than 500 psi gauges. When pressure exceeds 800 psi, the display shows "-OL-" and sounds an alarm.
±0.5% FS AccuracyPressure + Temperature in One
The PT-500Pro+ includes a temperature clip. Insert it to display superheat and low-pressure temperature directly on screen — no separate thermometer needed.
Temp Clip IncludedBluetooth App Monitoring
Connect to the Elitech Tools app to view live data, record offline (up to 3000 entries), export reports, and update firmware over the air. Temperature compensation improves leak-test accuracy.
Offline RecordingYour Phone Becomes the Diagnostic Station

-
Live Data Viewing
View real-time pressure and temperature on your phone via Bluetooth — no need to stand next to the gauge.
-
Offline Record — Up to 3000 Entries
Log data without a Bluetooth connection. Export via the app for review when you're back online.
-
Temperature Compensation
Compensates for internal pressure changes caused by ambient temperature swings — improves leak-test accuracy during pressure-holding mode.
-
OTA Firmware & Refrigerant Updates
Update firmware over the air and add refrigerant data via the app — no cables, no returns.
