Compact electrical measurements with pen-style handling

The Hapu HP-38B pen-type digital multimeter combines AC/DC voltage, resistance, diode, and audible continuity functions in a portable format. Auto-ranging controls and a backlit LCD help you select a function and review readings during suitable maintenance and troubleshooting tasks.

For an authorized equipment check, select the appropriate function, follow the manufacturer's connection procedure, and use display hold to record a reading before moving on. Confirm the meter and leads are rated for the circuit and environment before testing.

Verify electrical safety ratings before use

The listed maximum voltage is a measurement range, not proof of suitability for every circuit at that voltage. CAT rating, lead ratings, measurement accuracy, calibration status, battery requirements, and safety certification documentation are not provided in the available details.

Follow the exact unit's manual and appropriate electrical safety procedures. Resistance, diode, and continuity checks should be performed on de-energized circuits with stored energy discharged according to the equipment instructions. This listing does not establish current measurement, non-contact voltage detection, or data-logging capability.

Confirm included leads, batteries, accessories, product weight, country of origin, verified barcode/GTIN, and packed dimensions before relying on those specifications.
