What makes this pressure gauge easy to use in the field?
It features a hook design for easy fixing, so you can hang it securely while working, and wireless Bluetooth connectivity means no cables getting in the way.
Can I set pressure alarms?
Yes — you can set custom high/low pressure alarms, and the device provides high/low pressure indication to alert you when levels exceed your set thresholds.
What measurement units are supported?
You can switch between multiple pressure units to match your preferred working standard.
How do I connect the gauge to my phone?
Simply pair it with the free Bluetooth app — no additional hardware or subscriptions required.
Can it record data without being connected?
Yes — it stores up to 8,000 data points and supports off-line recording. You can export data reports for analysis and documentation.
What is the temperature clamp used for?
The included UT-T19 temperature clamp measures surface temperature, which pairs with pressure readings for superheat/subcooling calculations.
Which refrigerants are supported?
10 refrigerants are built directly into the device, with 90+ more available for easy switching through the app — covering virtually all common HVAC/R refrigerants.
How big and heavy is the device?
The gauge (UT336P) measures 145 × 68 × 39 mm and weighs 250 g; the temperature clamp (UT-T19) measures 154 × 88 × 24 mm.
Who is this tool designed for?
It’s ideal for HVAC/R technicians for refrigerant charging, system diagnostics, leak testing, and maintenance on air conditioning and refrigeration systems.
