The OW9800 Series includes the OW9820 and OW9825 high-voltage digital multimeters. OW9820 supports voltage measurement up to 2000V, while OW9825 supports measurement up to 2500V. Both models feature a 3 5/6-digit True RMS display and support AC/DC voltage, AC/DC current, resistance, capacitance, frequency, diode, continuity, and temperature measurements. The multimeter provides full-range anti-burn and overload protection for enhanced safety during electrical testing. Additional functions include non-contact voltage detection, relative measurement, data hold, overload indication, low-battery alert, and customizable auto power-off. Its double-injection molded housing combines a hard plastic structure, PC inner frame, and soft TPU outer layer to provide improved durability and grip. The OW9800 Series is suitable for high-voltage electrical testing, industrial maintenance, power-system troubleshooting, and field-service applications.
