Essential Electrical Testing in a Pocket-Size Meter
The HK39E is a compact True RMS digital multimeter created for everyday voltage, resistance and circuit checks. Its SMART/AUTO range selection simplifies routine measurements, making it a practical choice for maintenance technicians, electrical installers, property service teams and users who prefer a streamlined instrument rather than a meter crowded with specialist modes.
The meter measures AC and DC voltage up to 600 V and resistance up to 20 MΩ. A 1,999-count display presents results clearly, while non-contact voltage detection and live wire recognition support preliminary conductor checks before direct measurement. For circuit troubleshooting, the HK39E also includes diode test and an audible continuity buzzer.
At only 119 × 65 × 30 mm and 130 g, the HK39E fits easily into a tool pouch, work bag or service kit. Its LCD backlight, built-in flashlight, data hold and automatic power-off functions make it convenient for inspections in cabinets, utility areas and other locations where access or lighting may be limited.

Typical Applications
Residential Electrical Checks
Check supply voltage, continuity and resistance during outlet, lighting and household wiring maintenance.
Property and Facility Maintenance
Carry out routine inspections of switches, fuses, cables and powered equipment without adding a full-size meter to the service kit.
Appliance Troubleshooting
Measure incoming voltage, investigate open circuits and test basic connections when servicing household or light commercial appliances.
Installation and Field Service
Use the compact meter for commissioning checks, maintenance visits and general electrical fault finding.
Battery and Cable Inspection
Test common 1.5 V and 9 V batteries or use continuity mode to identify broken cables and poor circuit paths.
