Description

Testboy PROFI III DUO two-pole voltage tester with automatic test range selection (single-pole phase search, continuity tester, data hold, LC display and measuring point lighting, one-hand operation)Description:The Testboy PROFI III DUO two-pole voltage tester is the ideal electrician's tool for quick and efficient voltage tests. With a protection class of CAT IV 1000V, it can safely and reliably measure voltages from 6 to 1000V AC and 6 to 1500V DC. Thanks to the automatic test range selection and the single-pole phase search, the voltage tester can be used quickly and easily. The test can be carried out without finger contact and the measurement result can be read in the dark thanks to the measuring point lighting. The illuminated LC display and the one-handed function for Schuko sockets make the Testboy PROFI III DUO two-pole voltage tester a practical and efficient current measuring device for sockets. The thick, unscrewable measuring tips ensure easy use on sockets. In addition, the voltage tester can also be used as a continuity tester and a rotating field measuring device. The Testboy PROFI III DUO is a reliable current tester and voltage tester for every electrician. Details: - 6 to 1000V AC voltage - 6 to 1500V DC voltage - Protection class CAT IV 1000V

Key Features

Voltage test without battery: The voltage tester with continuity measurement is able to detect voltages even without the use of a battery. This is particularly useful in unpowered environments.

Contactless testing: Thanks to the measuring point lighting and the thick, unscrewable measuring tips, a safe test can be carried out without finger contact. This minimizes the risk of electric shock and makes work easier.

Continuity test with data hold: The integrated continuity tester with data hold allows measurement values to be saved and checked, which is particularly useful when multiple measurements need to be taken at different locations.

Single-pole phase search: The single-pole phase search makes it easier to identify the phase during a measurement. This is particularly useful when there are multiple wires in a cable duct or outlet.

Flexible application options: The tool offers a variety of measuring functions, such as continuity testing, three-pole rotating field testing, alternating and direct voltage testing, to be prepared for every application.
