Profi III LCD+
The new Profi III LED+ and Profi III LCD+ voltage testers are characterized by their user-friendly handling, the robust, safe construction and conformity to all requirements placed on modern voltage testers by a specialist. Due to the high safety classification, CAT IV 1000 V, the detectors are also suitable for measurements on hybrid and electric vehicles, as well as photovoltaic installations.
The voltage testers Testboy Profi III LCD + can also measure resistance up to 1999 Ω and indicate frequency up to 1000 Hz.
To switch on the device, simply hold the test probes on one another.
Attaching and removing the measuring probe adapter makes it easier to carry out measurements at the socket.
If the threshold value of 35 V AC/DC is exceeded, a signal sounds and lucid vibration can be felt. This indicates a general hazardous voltage!
Indication of the voltage is carried out without the batteries.
Because of the high protection class (IP65), the Testboy® Profi III LED+ and Profi III LCD+ can also be used under rugged conditions.
