TESTEC TT-HVP 40 High-Voltage Passive Multimeter Probe

Overview

The Testec TT-HVP 40 is a high-voltage passive probe designed to safely measure DC voltages up to 40 kV and AC voltages up to 28 kV RMS (0-300 Hz) using multimeters with 10 MΩ input impedance. Its 1000:1 division ratio ensures accurate scaling, reducing input voltages to measurable levels while maintaining precision (±5% for DC, ±6% at higher ranges). Unique to this probe is its dual division ratio capability: 1000:1 when paired with 10 MΩ meters and 2000:1 for 1 MΩ meters, offering flexibility across equipment.

The probe features a 1000 MΩ input resistance and minimal capacitive loading, minimising circuit disruption—critical for sensitive high-voltage applications like power supply testing or industrial diagnostics. Safety is prioritised with reinforced insulation, a mandatory grounding clip, and compliance with CAT I standards for low-energy circuits. Engineers benefit from its robust design, rated for altitudes up to 4,600m and humidity tolerance (80% at 40°C), ensuring reliability in harsh environments.

For professionals requiring precision in high-voltage measurement without compromising safety, the TT-HVP 40 combines critical specifications—wide bandwidth (300 Hz), low-temperature coefficient (<200 ppm/°C), and durable construction—into a tool that simplifies risk-prone tasks. Its compatibility with standard multimeters makes it an essential upgrade for labs or fieldwork demanding accuracy at extreme voltages.
