l  Battery powered,the instrument test insulation test

Insulation up to 100000MΩ at 2500V for Model 2550

100GΩ at 2500V and 200GΩ at 5000V for Model 2520,

200GΩ at 5000V and 400GΩ at 10000V for Model 2503,

l  Suited for heavy duty electrical maintenance and servicing of industrial installations,cables , transformers, generators and  switchgear where high voltage insulation tests are required.

l  Dual scales for low and high ranges which changes change  automatically.Colour coded scales for easy reading plus LED`s that illuminate in matching colour.

l  Hard carrying case furnished as standard accessory. Houses both instrument and test leads in compact from. Made of plastic, it is highly water resistant.

l Desianed for low power consumption. Since the maximum current consumption is 90mA eight pieces  of 1.5V SUM-3(or equivqlent) permit adout 6 hours of continuo us operation even when the instrument in used on maximum load or twice longer minimun load.

l Rated output voltage is maintained down to 100MΩ for Model 2550 ,0.1GΩ/0.2GΩ for Model 2520 and 0.2GΩ/0.4GΩ for Model 2503. This permits accurate measurements of low insulation resistance.
