The Elcometer 236 is available in two, fully adjustable, test voltage ranges, 0 – 15 kV and 0 -30 kV. The light weight, portable, rugged and simple-to-use instrument is supplied complete with a brush probe and uses a fully enclosed rechargeable battery pack as its energy source. Charger units for any mains voltage, 230V UK standard plug, 230V European
standard plug or 110V US standard plug are supplied according to the customer's choice.
To avoid the difficulty of field recharging, an optional external batter pack is available that can be charged separately and then plugged into the instrument to by-pass the internal battery and provide further testing time.
The convenient carry-case, also included in the instrument kit, has straps for carrying the probe when it is not in use and a simple twist-and-lock pouch location for the spare battery pack or the mains charger unit. The instrument, in its carry-case with the probe fitted, weighs 2.8 kg and can be easily carried over the shoulder.
A full range of probe options is available including:
- Right-angle probes in either phosphor-bronze wire or conductive rubber for large test areas; Circular wire brushes with a range of diameters for internal pipe coatings;
- Rolling-spring probes for external pipe coatings;
- Extension-pieces where long reach is required.
