Insulation Testers
The purpose of an insulation resistance test is to determine the integrity of the insulating material that surrounds electrical wiring within cables and items of machinery. Copper and aluminium are two of the most widely used materials in wiring electrical devices. To keep the electricity flowing in the right direction and properly insulated, the conductive core is enclosed in an insulating material.
Our Insulation Testers test the integrity of this material, as Insulation can degrade over time due to a myriad of factors, including extreme environmental and temperature conditions (UV, heat and cold), incorrect cable usage (under-voltage or -over-voltage) and chemical or blunt trauma damage (motor oil, plant grime and machine movements), which is why regular insulation testing is essential in maintaining insulation soundness. Test4Less stocks a huge selection of both digital and analogue insulation testers, ideal for domestic, industrial, and commercial usage.
