Broader Component Diagnostics Without the Bulk
The HK39G extends pocket-size electrical testing beyond basic voltage and resistance measurements. Along with True RMS AC voltage capability, it measures capacitance up to 40 mF and frequency up to 10 MHz. This broader range makes it particularly useful for electronics servicing, equipment maintenance, control-system checks and component diagnostics where a compact voltage-only meter may not provide enough information.
Its 3,999-count display offers increased reading resolution compared with the entry-level HK39E. SMART/AUTO range selection supports an efficient workflow across changing measurements, while resistance coverage up to 40 MΩ accommodates a wide selection of electrical and electronic checks.
Practical field features include NCV detection, live wire recognition, diode test, continuity buzzer and data hold. The LCD backlight and built-in flashlight improve visibility around control cabinets and equipment interiors. Measuring only 119 × 65 × 30 mm and weighing 130 g, the HK39G brings useful component-testing functions into a genuinely portable instrument.
