Water Pasteurization Indicator (WAPI)
Disease-causing organisms in water are killed by exposure to heat in a process known as pasteurization. Water heated to 65°C (149°F) for a short period of time is free from microbes, including E. coli, Rotaviruses, Giardia and the Hepatitis A virus.
Our new and improved WAPI contains a heat specific soy wax that helps users determine when water has reached pasteurization temperatures. The WAPI now has the added benefit of a tough stainless steel cable and brass end caps. Both are designed to withstand high heat which means they won’t melt when used over an open flame. This feature makes the WAPI especially valuable when used over an open fire, like camping or in situations where solar cooking is not an optio
