DET Earth/Ground Clamp-on Testers

The new DET14C and DET24C are advanced new earth / ground clamp-on testers that set new standards in terms of access, features, simple operation and safety.

These Instruments are a completely new design, being both engineered and manufactured at the Dover manufacturing site in the UK. Designed with flat core ends they prevent dirt build up, ensuring measurement integrity and improved reliability over previous products with interlocking teeth. Other enhancements include improved accuracy, ultra-high battery life, safety to CAT IV 600V and a built-in filter function for electrically noisy environments.
