The NEW Socket & See DLMPRO has been specifically designed with the gas and electrical appliance engineer in mind. It combines a socket test, loop test and selected basic multimeter functions to create another Socket & See First. The DLM PRO is the first tester to combine all the test procedures undertaken in a service and maintenance situation as followed by some of the UK’s leading appliance care companies. Development was undertaken alongside key customers and with a specification aimed reducing costs for the user. Combining the individual tests into a compact and handheld tester means less things to carry and less complicated products to understand. Its robust, ergonomic design and colour coding make it safe and simple to use.
