OWON OW9800 Series High-Voltage Handheld Multimeter
OWON OW9800 high-voltage handheld multimeter — OW9820 (2000 V) and OW9825 (2500 V, with HV module). 6000-count True-RMS, NCV, temperature and more.
A True-RMS handheld multimeter built for high voltage
The OWON OW9800 series measures far beyond an ordinary handheld meter — up to 2000 V on the OW9820 and up to 2500 V DC on the OW9825, which ships with a dedicated high-voltage test module. Both are full-featured 6000-count True-RMS meters with non-contact voltage (NCV), temperature and the complete set of everyday functions, so one instrument covers routine work and the high-voltage measurements a standard 1000 V meter can’t.
Choose the OW9820 for work up to 2000 V, or the OW9825 when you need to reach 2500 V DC for solar-string, battery-pack, EV and industrial testing.
Measure where standard meters stop
Most handheld multimeters top out around 1000 V. The OW9800 series is purpose-built to measure high voltage safely — with True-RMS accuracy and, on the OW9825, a plug-on high-voltage test module.
What the OW9800 series does
High-voltage measurement
Up to 2000 V (OW9820) or 2500 V DC (OW9825, with the supplied high-voltage module) — well beyond a standard 1000 V meter.
6000-count True-RMS
A 3⅚-digit display with True-RMS AC for accurate readings on distorted and non-sinusoidal signals.
Full function set
DC/AC voltage & current, resistance, capacitance, frequency, duty cycle, temperature, diode, continuity and NCV.
Field-ready & safe
Non-contact voltage detection, backlight, data hold, relative reading and auto power-off in a rugged handheld.
Ideal for
- Solar PV strings, battery packs and EV systems with high DC bus voltages
- Industrial, panel and electrical maintenance above a standard meter’s range
- Anywhere you need one meter for both everyday work and high-voltage checks
- OW9825 + high-voltage module for measurement up to 2500 V DC
Typical measurements
- DC / AC voltage up to 2000 V (OW9820) or 2500 V DC (OW9825)
- DC / AC current (µA / mA / A ranges), True-RMS
- Resistance, capacitance, frequency, duty cycle and temperature
- Diode, continuity and non-contact voltage (NCV)
OW9820 or OW9825
Both models are selected from the variant dropdown on this product. They share the same 6000-count True-RMS platform — the OW9825 adds a higher voltage ceiling and the plug-on high-voltage test module.
