## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA270:1` (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/ADA270:1.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

Thermocouples are best used for measuring temperatures that can go above 100 °C. This is a bare wires bead-probe which can measure air or surface temperatures. Most inexpensive thermocouples have a vinyl covering which can melt at around 200 °C, this one uses a fiberglass braid so it can be used in high temperature measurements such as heaters and ovens. There's a small piece of heat shrink on the end to keep the fiberglass from fraying. If you're using at >250°C temperatures, simply remove it with a small blade.

- K type thermocouple with glass over-braiding
- Good up to 500 °C (900 °F)!
- Color-coded wires
- 1 meter long (a little more than 3 feet)
- [Best used with a thermocouple amplifier such as the MAX6675 or MAX31855](https://core-electronics.com.au/thermocouple-amplifier-max31855-breakout-board-max6675-upgrade-v2-0.html)
 
Adafruit have a handy tutorial which covers thermocouple use including an Arduino library and example code!
 
 **Please note:** Adafruit seem to have gotten a few thermocouples that have the red&yellow wires color-coded wrong. It will not damage the thermocouple or sensor if the wires are connected backwards, but temperature readings will go the 'wrong way' so if you find that the temperature is dropping when you heat up the sensor, try flipping the wires!
