This GS38 complaint contact voltage indicator is designed to rapidly and safely check for AC and DC voltages from 50V to 600V. The bright, long life neon indicators give clear and immediate display of the voltage level range. The tough, moulded case construction combined with heavy duty, double insulated leads which terminate into a lockable and retractable prod sheath and a substantial finger guard makes this a very reliable and safe instrument. The return lead incorporates an HRC fuse which, together with the retractable test prods, ensures that the unit fully meets all the GS38, M15/4, HSE and EN61010 recommendations.
