The UEi DL599 True RMS HVAC/R Power Clamp Meter is an award-winning wireless instrument designed specifically for HVAC electrical diagnostics. Featuring 3-phase motor rotation testing, unbalanced motor analysis, and power factor measurement, the DL599 connects to measureQuick via Bluetooth for integrated electrical and refrigerant-side diagnostics.

Advanced Electrical Diagnostics

The UEi DL599 clamp meter goes beyond basic voltage and amperage readings. True RMS measurement ensures accurate readings on variable frequency drives, ECM motors, and other non-linear loads common in modern HVAC systems. The 3-phase motor rotation and imbalance testing capabilities make the DL599 essential for commercial service work, where identifying phase issues can prevent costly compressor failures.

measureQuick Wireless Integration

The DL599 streams real-time electrical measurements directly to measureQuick via Bluetooth. This integration allows technicians to capture voltage, amperage, power factor, and wattage data alongside refrigerant pressures, temperatures, and airflow measurements in a single diagnostic session. measureQuick automatically correlates electrical readings with system performance data, helping identify issues like locked rotor conditions, overloaded circuits, and degraded capacitors.

Built for HVAC Professionals

With its CAT III safety rating and rugged construction, the UEi DL599 is purpose-built for the demands of field service. The wireless Bluetooth connection eliminates cable clutter during diagnostics, while the built-in LED work light helps technicians work in dark mechanical rooms and attic spaces. Combined with measureQuick’s automated reporting, the DL599 helps technicians document electrical findings professionally and communicate system issues clearly to homeowners.
