When properly specified, socket testers provide a fast and effective solution to identify potentially unsafe installations and wiring faults. They can be particularly useful as a service tool for identifying potentially unsafe conditions prior to installing new plant and equipment. Socket testers are not an alternative to the full verification of wiring installations, however they are an essential tool for all maintenance teams as a first line indicator.
Annual calibration of test and measurement equipment is recommended by the vast majority of manufacturers and it may also be appropriate to carry out more frequent calibration should test results start to fluctuate. However, the processes behind loss of accuracy are often little understood and they are influenced by a wide array of factors. This article aims to explain the influences behind variations in accuracy and clarify the actual calibration process your tester will undergo when it comes to our laboratory.
We have quality clamp meters that measure both high and low AC and DC currents as well as earth leakage and earth resistance clamp meters from Megger, Metrel, Kewtech, Extech and Martindale. With variable jaw sizes, max current readings up to 2000A AC/DC and features including TRMS, data logging and temperature readings we have current clamps suitable for a wide range of electrical applications.
We supply a range of clamp meters from manufacturers such as Martindale, Megger, Kewtech, Metrel, Extech, FLIR and Testo. Whether you require an earth leakage clamp to test a BS7671 low voltage electrical installation for earth leakage current, an AC/DC clamp typically used for a variety of current measurements including solar PV circuits, or perhaps a flexible CT type clamp meter for safely measuring high current, we have a solution for you.
We pride ourselves on the support we deliver from our industry experts
