Insulation testers measure the electrical insulation strength between two conductors by applying a high voltage across them and measuring any current that flows. This is to test for “leakage” paths and insulation breakdown in electrical circuits. eg checking house wiring for leakage between active and neutral conductors or testing electrical appliances such as toasters, irons etc. This model features two resistance test ranges; 200MΩ and 2000MΩ with four test voltages on each range; 100V, 250V, 500V and 1000V. It also has auto power off to maximise battery life. The included high quality silicon test leads are designed specifically for insulation tester use and have removable alligator clip adaptors. Supplied with rubber holster and soft protective carry case. Features 200MΩ and 2000MΩ ranges Backlit LCD readout “Push to test” activation Auto power off Rubber holster Data hold High quality PVC leads Alligator clip lead adaptors Battery included Cat II 600V

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=AQ1242A:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/AQ1242A:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)
