FIELD: means of sterilization, applicable in veterinary science, processing of food products and in various production processes using sterilization. SUBSTANCE: thermotiming indicator has a backing and an indicator element made of polymeric film based on polyvinyl chloride. The thickness of this film makes up 50 to 200 μ. A transparent coating is applied over it. The indicator element backing is laminated, and one of the layers is made of the same material as the coating. The width of the backing of the indicator element and the width of its coating may exceed the width of the indicator element. EFFECT: simplified process of manufacture and enhanced reliability. 3 cl
