Checking temperature probes

Control of a heat treatment process involves having to control the main parameters that guarantee treatment efficacy, i.e. temperature. Generally speaking, this means making sure that the temperatures recorded during a batch treatment are conform with the initial set temperature and, therefore, that the temperature measurement chain is providing reliable data. Use of this method forms part of the mandatory quality assurance process for plants certified to ISO 9002. This means of guaranteeing product quality is both faster and more cost-effective than the analytical control.
