The UEi HAC True RMS High Accuracy Clamp Meter is measureQuick’s recommended instrument for precision electrical diagnostics. Featuring power factor measurement, wattage readings, and a 200A low-amp range, the HAC delivers the accuracy needed for VRF systems, variable frequency drives, and mini-split applications where standard clamp meters fall short.

High Accuracy for Modern HVAC Systems

The UEi HAC clamp meter features a 200A low-amp measurement range that provides the resolution needed for diagnosing mini-split, VRF, and inverter-driven systems. Standard clamp meters often lack the sensitivity to detect subtle current variations in these low-draw systems, making the HAC an essential tool for technicians working on modern high-efficiency equipment. True RMS measurement ensures accurate readings regardless of waveform distortion from electronic motor controls.

Power Analysis with measureQuick

When connected to measureQuick via Bluetooth, the HAC streams voltage, amperage, power factor, and wattage data in real time. measureQuick integrates these electrical measurements with refrigerant-side and airflow data to provide a complete system performance picture. This is particularly valuable for VRF and mini-split diagnostics, where electrical behavior directly reflects compressor modulation and system health.

Why measureQuick Recommends the HAC

The UEi HAC earned measureQuick’s recommendation because of its combination of accuracy, power analysis capabilities, and reliable Bluetooth connectivity. For service companies standardizing on measureQuick, the HAC provides the electrical measurement foundation needed for comprehensive HVAC diagnostics. Its ability to measure power factor and calculate wattage directly eliminates guesswork when assessing compressor and motor efficiency in the field.
