Thermindex | X-ON
Thermindex is a Color Change Thermometry.This type of indicator generally consists of a temperature-sensitive chemical that has been fixed over a black surface. When heated, the chemical melts and becomes transparent, whereupon the underlying black surface appears. This technique is used for temperature gauges in many different forms and sizes. Gauges intended for indication of low temperatures (up to 160°C) are sealed in polyester. For gauges intended for temperatures above 170°C, Polymide (Kapton) is used. The result is a low-weight product that is easy to apply and to use. Effectively the chemicals have an accuracy of +/- 0,1°C, which in practice is specified as 1°C. The reaction time is short – a maximum of 1 second. The chemicals are sensitive to moisture and pressure above 100 psi, which is why they have been encapsulated, in order thereby to achieve as wide a range of application as possible.
