Ergonomics, durability, reliability

The Sonel P-4 bipolar voltage indicator is a reliable, extremely durable and safe bipolar tester, which allows to check voltage, continuity of circuit and phase sequence. It is designed to operate in the harshest environments, both industrial and commercial. Advanced technology, high level security and ease of use are the key features of the P-4. The device is equipped with a robust IP65 casing, which protects the device from mechanical damage, dust and splashing.



Main functions and attributes of the P-4 instrument.

  • automatic voltage tests 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
  • HOLD function for freezing the measurement results.
  • robust, two-component housing protecting from mechanical damages and impacts.
  • 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 standards.


Residual-current device trip testing

In response to the needs of clients, our new P-line voltage testers allow to check the RCD in a fully controllable way. With buttons on both probes, the user can reduce the internal impedance of the instrument, which makes it possible to trip the RCD. Additionally, pressing both buttons activates an additional load point - a vibration motor. In this way, voltage can be measured in a tested circuit with no impact of stray currents on the result.


Durability and comfort of use

The housing has been designed for use in harsh industrial environments, where the application of personal protection equipment, such as voltage insulation safety gloves, is required. At the same time, the instrument’s ergonomic shape allows for one hand use.


Versatility and safety

Voltage testers are provided with a set of test probes. The probes reduce metal exposure to 4 mm length, which eliminates the risk of accidental contact with the wrong conductor when performing measurements on a wire harness. Additional screw-on metal adapters are used for applications where tips with 4 mm diameter are required. It is particularly important for tests in electrical sockets, where the user must be sure that contact between the probe and the conductor is kept. All elements of the set are stored in a special case so the probe tips can be replaced when needed. The case also includes an adapter that is helpful for unlocking the UK-type sockets.
