With its 1.6 kg, the electromagnet LKNB-22016A + is presented as the most compact model on the market. Ultra light and handy to relieve operators and facilitate working conditions while remaining robust to withstand the most hostile environments, it allows to make checks in magnetic particle without worrying about access to power. Its lithium-ion battery supplies it with 110 V alternating current, thus giving total freedom for more than 3 hours continuously, sufficient for a day of conventional control. An upgraded version offers even more than 6 hours of autonomy. A single button is used to switch from AC to DC (direct current). The equipment can also be used on mains. In compliance with the ISO 9934-3 standard, the electromagnet raises a mass greater than 4.5 kg. The integrated white light of over 500 lux also assists the operator in the dark by meeting the standard lighting requirements. All models are delivered in a rugged carrying case with belt to place the electromagnet, battery, cable and aerosol products. Two beveled hooves for fillet weld checks are also part of the kit.
