Kewtech JAWS Open Jaw Current & Voltage Tester

Kewtech JAWS Open Jaw Current & Voltage Tester combines current, voltage, resistance and continuity measurement in a compact electrical test instrument. Its open jaw design allows AC and DC current measurement up to 200A without direct contact with the conductor. True RMS measurement is used for AC voltage and AC current, while automatic AC/DC selection helps reduce the number of manual settings needed during testing.

A backlit LCD keeps readings clear in lower light levels, while hold and relative functions make it easier to retain and compare measurement data. The built-in resistance function covers values up to 40MΩ, and the continuity buzzer sounds below approximately 500Ω. Probe retention on the rear also supports two-pole testing while keeping the instrument compact and practical to handle.

Kewtech JAWS Open Jaw Current & Voltage Tester weighs approximately 250g without batteries and measures 235 x 60 x 32mm. The test leads wrap around the instrument when not in use, helping keep them organised during storage and transport. It runs from two AAA batteries and carries an IEC 61010 CAT IV safety rating, with CAT IV 600V stated for current measurement.

 

Key Benefits
  • Open jaw current measurement allows quick access without a conventional closing clamp.
  • Measures both AC and DC current up to 200A for flexible electrical testing.
  • True RMS AC voltage and current measurement supports accurate readings.
  • Automatic AC/DC selection reduces manual switching during measurement.
  • Backlit LCD improves reading visibility in dimly lit working areas.
  • Hold and relative functions help retain and compare displayed readings.
  • Rear probe retention supports convenient two-pole testing.
