How color changes

Specially designed label for vaccum condition from 1Pa to the atmospheric pressure

Temperature range:40~210℃
Strictly under the control of ISO9001:2008 QC system.
RoHS Compliant

Vacuum Thermo Label is label type temperature indicator able to use under vacuum environment (1Pa~ordinary pressure). Temperature monitoring can be done without wiring and electric powers supply just by applying this label on where it is necessary. Color-changing area changes its color from light yellow to black when response temperature is exceeded.
