Kewtech KEWISO2 Essential Safe Isolation Kit

Kewtech KEWISO2 Essential Safe Isolation Kit provides a complete solution for safe isolation procedures. It helps engineers confirm circuits are dead before work begins. This reduces risk and supports safe working practices on site.

Built for daily use, the kit combines a voltage tester, proving unit and lock off device in one case. As a result, users can carry out checks quickly and with confidence. The design also keeps all tools easy to access.

Reliable Testing Performance

Kewtech KEWISO2 supports AC and DC voltage testing up to 690V. It includes clear LED indication and an audible tone to confirm voltage presence. This ensures results are simple to read even in low light areas.

In addition, the unit carries out continuity, polarity and phase rotation checks. These functions help verify correct installation and safe conditions. The tester also runs a self check to confirm it is working before use.

Designed for Safety and Ease

The kit meets IEC 61243-3 and IEC 61010-1 standards, so it aligns with modern safety rules. It also includes a KEWLOK device that fits most breakers without keys. This makes lock off fast and simple on site.

Kewtech KEWISO2 comes in a durable carry case with space for each item. The proving unit can be used without removal, which saves time. Together, these features improve workflow and reduce delays.

 

Key Features

  • Supports safe isolation procedures on site
  • Two pole voltage tester for accurate readings
  • Clear LED indicators for voltage levels
  • Audible tone for quick voltage confirmation
  • Integrated torch for low light environments

Kewtech KEWISO2 Essential Safe Isolation Kit

Kewtech KEWISO2 Essential Safe Isolation Kit brings together the main tools needed to support safe isolation procedures on site. It combines a two-pole voltage and continuity tester, a high-output proving unit and a universal lock-off device in one carry case. This helps electrical professionals keep the required equipment together and ready for routine testing and isolation work.

The KT1780 tester measures AC and DC voltage from 12 V to 690 V and gives clear luminous LED indication with an audible tone. It also provides continuity, polarity, single-pole phase and phase rotation functions, while an integrated torch helps when working in low-light areas. Its probes can reach recessed terminals without the need to remove probe caps, and automatic power on and off supports straightforward daily use.

Kewtech KEWISO2 Essential Safe Isolation Kit also includes the KEWPROVE3 proving unit so the voltage tester can be checked before use. The KEWLOK device uses an integrated combination padlock and is designed to fit MCBs and most toggle main switches without separate keys. A carry case with internal storage keeps the kit organised and allows access to the proving unit while it remains in the case.

 

Key Benefits
  • Combines testing, proving and lock-off equipment in one kit for convenient site use.
  • Measures both AC and DC voltage across a 12 V to 690 V range.
  • Luminous LED indication and an audible tone make voltage status easy to identify.
  • Integrated torch improves visibility when working around terminals in low-light areas.
  • Continuity, polarity and phase rotation functions support a wider range of electrical checks.
  • Self-diagnostic testing helps confirm that the KT1780 is operating before use.
  • KEWPROVE3 provides a high-output proving source for checking the two-pole voltage tester.
  • KEWLOK uses an integrated combination padlock, removing the need for separate lock keys.
  • Rugged carry case provides internal storage and keeps the main kit components together.

 

Common Applications

Kewtech KEWISO2 Essential Safe Isolation Kit is suitable for a range of testing, maintenance and inspection tasks, including:

  • Safe isolation procedures before electrical work begins.
  • AC and DC voltage testing on electrical circuits.
