Elcometer 236 DC Holiday Detector

The Elcometer 236’s convenient carry case allows the probe handle and accessories to be attached to the front making the Elcometer 236 holiday tester ideal for field, site or laboratory inspection.

The Elcometer 236 provides the user with complete control of voltage and sensitivity settings and is available in 2 versions, 15kV and 30kV.

Each unit is supplied in a convenient carry case which also holds the probe handle and an additional (optional) external rechargeable battery pack which doubles the testing time available.

An accessory pouch, which accommodates the additional rechargeable battery (optional) can also be attached to the soft carry case - thereby extending inspection time without the need for recharging the unit.

  • Robust and fully portable
  • Audio and visual alarms for noisy environments
  • Supplied with a band brush probe
  • Digital display of output voltage or current
  • Adjustable sensitivity
  • 15kV and 30kV options available with fully adjustable output voltage

Due to its unique design, the probe handle can be replaced with a telescopic probe handle - extending the measurement reach up to almost 4m (13’), ideal for testing on large/high structures.
