HT Instruments COMBI419 Multifunction Safety Tester

1. Киришүү

The HT Instruments COMBI419 is an innovative multifunction installation tester designed to perform comprehensive safety tests on electrical installations. It complies with recent standards such as VDE0100 and BS7671, and is capable of measuring leakage currents. This instrument is user-friendly, featuring a multi-language menu and a wide array of internal functions.

The COMBI419 allows for principal measurements to be initiated using an optional remote probe (PR400 accessory), which is particularly useful for quick tests. It also includes an internal AUTO function for sequential measurements of Global Earth Resistance, RCD tests, and Insulation directly on civil installation sockets. A contextual help menu is available for each measurement function, providing valuable information regarding meter connection to the installation. Its robust electronic function selector ensures durability for field use. The device includes a large internal memory for saving measurements, which can be transferred to a PC via a serial port using dedicated software. Each saved measurement includes all sub-results and test parameters, with up to two user-selectable ID locators for precise identification of the test location.
