Toronto, Canada - GAO Instruments ( has released its digital insulation resistance tester. The intelligent digital device is specially designed to predict, prevent and identify insulation failures that may cause appliance failure, stop production and create power problems or even put lives at risk. It accurately tests insulation integrality on all kinds of electric equipment and insulation materials found in equipment such as transformers, electro-motors, cables, switches and other installed wiring.
The affordable digital tester, model A0300029, tests insulation resistance up to 2000MÃŽ©. With a built-in high power voltage generator, the output testing voltage is adjustable over 250V, 500V or 1000V depending on requirements. Alternating current can be measured; voltage below 750V AC can be tested. Due to its multiple test voltages, this advanced digital insulation resistance tester is ideal for many troubleshooting, commissioning, and preventative maintenance applications. The well-designed tester offers a large backlit LCD screen making it suitable for use under bright sunlight or in poorly lit environments. Encapsulated in a rugged and moulded plastic case, this high performance digital insulation resistance tester is an invaluable tool for field testing.
