UT336P Wireless Pressure Gauge

UNI-T UT336P Wireless Pressure Gauge

The UNI-T UT336P Wireless Pressure Gauge is a smart and versatile HVAC/R diagnostic tool designed for installation, maintenance, and long-term monitoring of refrigeration, heat pump, and air-conditioning systems. It delivers real-time pressure readings wirelessly to your phone via Bluetooth, supports offline data logging, and when paired with an external temperature clamp (e.g., UT-T19), it enables calculation of superheat and subcooling, making system checks faster and more accurate.

Key Features

• Wireless Bluetooth connectivity with the iENV app for real-time monitoring, data export, PDF/CSV reports, and firmware updates.
• Wide pressure range suitable for HVAC/R systems.
• Offline data logging: Stores up to 8,000 records with configurable intervals.
• High/Low pressure alarms and dual LED indicators (HP/LP) for quick status checking.
• Temperature clamp port: 3.5 mm interface for external temperature probe to measure pipe temperatures and calculate superheat/subcooling.
• Multiple pressure units supported for flexibility (bar, psi, kPa, MPa, etc.).
• Preset refrigerants: 10 built-in, with 94+ available via app.
• IP54 dust and splash resistance for field durability.
• Auto power-off and firmware upgrade via app.
