Historical information

A floating dairy thermometer is a typically mercury-free device designed to float vertically in liquids, allowing for continuous hands-free temperature monitoring in tasks like cheesemaking, yogurt production, and pasteurizing milk. It provides at-a-glance, precise 1°C accuracy measurements, often featuring a weighted bottom and a large, easy-to-read scale.
