The Honeytek HK39L is a compact, pocket-size digital capacitance meter designed for measuring capacitors across a wide range from 200pF to 20mF.
Its nine manually selectable capacitance ranges help users choose the appropriate measurement level for small ceramic capacitors, film capacitors, electrolytic capacitors and other electronic components. The meter provides up to ±(0.5% + 5 digits) accuracy across its principal measurement ranges.
For easier inspection and comparison work, the HK39L includes a relative measurement mode, data hold, LCD backlight and automatic capacitor discharge. Its lightweight 130g body and two-AAA battery supply make it convenient for field servicing, repair benches, laboratories, production lines and electronics education.
Key Features
Wide 200pF to 20mF Measurement Range
Nine selectable ranges cover low-value components measured in picofarads through large capacitors measured in millifarads.
Up to ±(0.5% + 5 Digits) Accuracy
The principal 2nF to 200µF ranges provide dependable measurement accuracy for capacitor inspection, component matching and troubleshooting.
Manual Range Selection
Manual ranging lets technicians select the measurement range based on the expected capacitor value, providing greater control during component testing.
Relative Measurement Mode
Relative mode can compensate for test-lead capacitance or establish a reference value when comparing similar capacitors.
Automatic Capacitor Discharge
The built-in auto-discharge function improves convenience when working with previously charged capacitors. Capacitors should still be safely discharged before connection and handled according to the applicable electrical safety procedures.
Data Hold and LCD Backlight
Data hold freezes the displayed value for recording, while the backlit LCD improves visibility in workshops, equipment cabinets and other low-light environments.
Portable Two-AAA Operation
The HK39L weighs approximately 130g and operates on two 1.5V AAA batteries, making it suitable for portable maintenance work.

Why Choose the HK39L?
The HK39L is a practical choice for users who need a lightweight, economical and dedicated capacitor tester without the additional measurement functions of a full-size multimeter.
Compared with basic meters that only provide a limited capacitance function, the HK39L offers nine dedicated capacitance ranges, relative measurement, automatic capacitor discharge and a maximum 20mF range. Its manual range control is particularly useful for technicians who prefer to select the measurement level directly.

FAQ
What can the Honeytek HK39L measure?
The HK39L is a dedicated digital capacitance meter. It measures capacitor values across nine ranges from 200pF to 20mF.
Is the HK39L an autoranging capacitance meter?
No. The HK39L uses manual range selection, allowing the user to select the expected capacitance range using the rotary switch.
What types of capacitors can the HK39L test?
It can be used with ceramic, film and electrolytic capacitors, provided their capacitance values fall within the meter’s specified 200pF to 20mF range.
Can the HK39L compensate for test-lead capacitance?
Yes. Its relative measurement mode can establish a reference value and help compensate for residual capacitance during low-value measurements.
What is the difference between the HK39L and A6013L?
The HK39L is smaller, lighter, manually ranged and powered by two AAA batteries. The A6013L provides automatic ranging, uses a 9V battery and has a larger body.
Should a capacitor be discharged before testing?
Yes. Always disconnect the capacitor from the circuit and safely discharge it before measurement. The meter’s auto-discharge feature should not replace proper electrical safety procedures.
