About Electrical Testers

Electrical testers check whether a circuit is live and whether wiring, insulation and components are healthy. This range covers simple line tester screwdrivers and non-contact voltage detectors used by electricians every day, along with bench and field instruments such as insulation resistance testers, withstanding voltage (hipot) testers, LCR meters, DC ohmmeters, teslameters and socket-type power meters used in panel shops, motor rewinding units, quality labs and maintenance teams.

Start with the job. For a quick live or dead check, a line tester or a non-contact voltage detector is enough, but confirm its voltage range covers your supply. For cables, motors and panels, an insulation resistance tester applies a set test voltage, so pick test voltages that match the equipment you check. Hipot testers are for production and type testing, while LCR meters measure inductance, capacitance and resistance of components. Check the CAT safety rating on any meter used on live circuits, use test leads in good condition, and always prove a tester on a known live source before and after use.

We list Fluke, INSIZE, Taparia, Stanley, Makita, Milwaukee and Groz at prices that include GST, with a GST invoice on every order and delivery across India. Electrical contractors, panel builders and maintenance departments buying in quantity can ask for a bulk quotation.

Questions buyers ask

What is the difference between a line tester and a voltage detector?

A line tester screwdriver lights up when its tip touches a live point. A non-contact voltage detector senses AC voltage through the insulation without touching the conductor.

When do I need an insulation resistance tester?

Use it to check the insulation of cables, motors, transformers and panels, for example before commissioning or during planned maintenance. A normal multimeter cannot apply the test voltage needed for this.

What does the CAT rating on a tester mean?

The CAT rating (CAT II, CAT III, CAT IV) shows the measurement category the tester is designed for. Choose a rating that matches where you will measure, such as sockets, distribution boards or the supply side.

Do prices include GST?

Yes. Prices include GST and every order gets a GST invoice.
