Sonel P-4 is reliable, particularly durable and safe 2-pole testers, which enable testing voltage, circuit continuity and phase sequence. It has been designed for use in extreme conditions both in industry and commercial applications. Advanced technology, a high level of safety and user-friendliness are the key features of the P-line voltage testers.

Main functions and attributes of the P-line instruments:

• automatic voltage test up to 1000 V AC/DC,


• optical indication by a LED bar,


• sound indication when dangerous voltage levels of 50 V AC and 120 V DC are exceeded,


• RCD trip test with switchable load,


• automatic continuity test upon connection to the object,


• 2-pole test of phase rotation direction,


• single-pole indication of 100 V presence,


• robust, two-component housing protecting from mechanical damages and impacts,


• integrated torch light for tests in poorly lit areas,


• IP65 ingress protection guarantees protection against dust and water,


• safety provided by measuring class compliant with CAT IV 600 V and CAT III 1000 V.
