Martindale Electric has introduced its latest NC series of non-contact testers, designed for identifying live wiring and detecting magnetic fields in a range of applications.
All models feature a bright LED torch at the point of measurement, together with both audible and visual indication. The extended clear probe tip makes it easier to identify the source of the live voltage or magnetic field through improved access and brighter indication.
Both NC2 non-contact voltage detector and NC4 dual sensitivity non-contact voltage detector are designed to make it simple to detect the presence of AC voltages in cabling, sockets and connectors. The sensitivity of the NC2 has been optimised for 230V single and three-phase systems, for identifying and tracing live mains cables in trunking and connectors. The NC4 features two sensitivity ranges which can be set according to the application and is suitable for both mains and lower voltage systems down to 12V.
The non-contact magnetic field detection capabilities of the NC1 non-contact solenoid/magnetic field tester and NC3 non-contact voltage and magnetic field tester can be used for checking the operation of relays and solenoid valves in a wide range of machinery. This feature saves time by allowing testing without having to dismantle equipment or control panels. For the dual function NC3, a bright red LED indicates voltage and a yellow LED magnetic fields. Suitable applications for both the NC1 and NC3 include trouble shooting and servicing of control equipment in process industries, energy, transportation and pneumatic and hydraulic systems.
The pen-shaped design with clip is designed for carrying in a pocket or tool belt so that the tester is always to hand for electricians or maintenance staff working at height or in difficult to access locations.
Available online and through electrical wholesalers, all models in the new NC series are supplied with alkaline batteries and a comprehensive two-year guarantee. Non-contact voltage testers are a handy tool for detecting live voltages and troubleshooting faulty wiring and equipment but cannot be used for proving dead during safe isolation procedures. A two pole voltage indicator such as the Martindale VI13800 should be used for proving dead.
