## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0454:1` (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/SEN0454:1.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)

## Description

Water leakage can pose a range of safety risks and cause significant financial loss. However, there is a solution to help prevent potential damage. This innovative water leak sensor utilizes an integrated NO/NC design that can detect both water leakage and shortages. With a relay output signal, the built-in relay is triggered when the two probes detect water, causing the alarm system to activate or equipment to switch off.

Not only is this water leak detector incredibly sensitive, but it also boasts a low false alarm rate and has waterproof and dustproof protection with an IP66 rating to ensure safe and reliable use. Ideal for use in various settings such as kitchens, hotels, base stations, and even factory warehouses, this device offers unparalleled safety and peace of mind. Plus, with an energy-efficient design, this device won't pose any risks to combustible materials.
