ACCURACY HAS TOP PRIORITY
In any production, accuracy of measurement is a key requirement. Accurate control of parameters such as temperature and adhering to defined ambient conditions when handling and storing products can have a significant effect on the quality of the end product. Testo offers a wide range of measurement solutions designed for daily use in the field to help you meet this challenge. We closely follow the latest developments in food engineering and law, and maintain close contact with food inspectors, so you can depend on the validity of our instruments.
Regardless of whether you wish to measure temperatures, air humidity or analytical variables such as the pH value, Testo has the most up-to-date and easy-to-use measurement solutions designed for everyday use in the field. For example, our new pH probes function with a gel electrolyte as a reference medium and are therefore leak-proof, maintenance-free and not affected by dirt ingress unlike conventional sensors. And because we know how important temperature measurement is, we offer a wide range of temperature probes with different sensors and designs to facilitate temperature measurements in practically every application imaginable, even field use.
