UNI-T UT336V Wireless Vacuum Gauge

Description

UNI-T UT336V Wireless Vacuum Gauge The UNI-T UT336V is a compact digital vacuum gauge with integrated Bluetooth connectivity, designed for accurate vacuum monitoring in refrigeration and heat pump applications. It helps technicians assess system dehydration and cleanliness during installation, commissioning, troubleshooting, and routine maintenance. Its multiple vacuum measurement units and ambient temperature measurement make it a versatile tool for professional HVAC/R work. The UT336V supports mobile app connectivity, stores up to 8,000 data records, and provides water saturation temperature and temperature-difference readings. It features an IP54-rated enclosure, a hanging hook, and a 1/4-inch SAE interface for convenient field use. The manufacturer lists compatibility with A1, A2L, A2, A3, and some B1 refrigerants; it must not be used with ammonia refrigerants (NH₃/R717).
