High Voltage Digital Voltmeter

The 149-10A is a high-voltage digital voltmeter built to measure AC and DC voltages up to 10 kV with high accuracy and reliability. Its high input impedance ensures that it can measure high-resistance or high-impedance circuits without significantly loading them — making it ideal for calibration of withstanding-voltage testers, insulation testers, or other high-voltage test equipment. Despite its advanced capabilities, the unit remains compact and lightweight, offering portability and convenience for field work or laboratory use. The 4½-digit LED display gives clear numerical readouts for precise readings, and the meter supports both DC and AC (rms) measurement modes, suitable for verifying or calibrating high-voltage outputs whether steady DC or AC. Its robust design and wide measurement range make it a reliable choice for electrical safety testing, insulation verification, and high-voltage lab applications where accuracy, input resistance, and measurement range are critical.
