Electrical Testers covers a range of equipment, from the simple volts sticks, to instruments, with more functions. Some are simply tool box instruments that are used to check the presents of voltage whilst others, have LCD displays, that can give a readout of the voltage present. Some come with their own dedicated proving unit, that enables the user to prove, first the voltage tester is fully functional, before using and then performing work on a system.
There are testers which plug into a 13 amp socket and can give a loop impedance reading , these are available from Martindale and Kewtech. Martindale and Kewtech check plugs which show correct polarity and fauls by means of neon indicator lamps, some have an audible sound, like the Martindale Buzz it check plug. There are Electrical Testers of different voltage ranges Martindale and Fluke produce many different products in this section some, showing voltage by a series of LED lights and some with LCD readouts. Voltage Testers are also available from the Tietzsch company. Most voltage testers are offered to you here, with a price saving on the makers quoted prices. Please browse the section. you can always telephone us to discuss your requirements, if you find it difficult to make a selection.The testers with LCD displays, are supplied with a free of charge calibration and certification.
