The Testo 750-1 is a two-pole digital voltage tester for measuring voltage, continuity and rotating magnetic field (phase sequence) in low-voltage electrical installations. It tests voltage from 12V to 690V AC/DC, with results shown on a patented all-round LED display using fibre-optic technology, so readings stay clearly visible whatever angle the tester is held at.
The all-round display steps through 12V, 24V, 50V, 120V, 230V, 400V and 690V, giving a clear visual indication of the voltage level detected. Continuity testing covers up to 500kΩ, and rotating magnetic field testing runs from 100V to 690V AC at 50/60Hz, useful for confirming motor rotation direction and verifying three-phase supply. Low input impedance reduces the risk of false readings from ghost voltages on circuits that are actually de-energised.
It's rated CAT III 1000V and CAT IV 600V, covering fixed building installations and utility-level supply circuits, and meets EN 61243-3:2010, the current European standard for two-pole voltage testers. The housing is IP64 rated for dust and splash resistance, with an anti-slip ring and ergonomic handle for a secure grip. It's CE, TÜV and CSA certified, and comes with batteries, a measuring tip protector and measuring tip caps included.
The all-round LED display is a genuine practical advantage over a single-face readout — voltage level stays visible whether the tester is held normally, sideways or backwards, which matters when working in awkward positions around a distribution board. Combining voltage, continuity and phase sequence testing in one CAT III 1000V / CAT IV 600V rated tool covers most low-voltage installation checks without needing separate instruments, and compliance with EN 61243-3:2010 confirms it meets the current standard for two-pole voltage testers.
