The HotSpot Scald Warning Triangle is a reliable and simple to use scald warning device. It has been designed for carers to provide a clear visual warning when water may be too hot for the comfort or safety of their clients. The Hotspot is very easy to use; simply drop the triangle into water and wait for the colour change. If the water is above 37ºC, the triangle changes from a dark purple to a vivid pink. The Vivid pink colour is a clear indication that caution is required. When the hotspot is removed from the water, it returns to its original colour.
