The traceable long-stem thermometer from this company can be used to fit into flasks, cuvets, test tubes and beakers. It reads temperatures in solids, gases, semi-solids and liquids. The stainless-steel probe is resistant to acids, bases, solvents and most HVAC chemicals. The long stem allows users to make measurements while stirring solutions in deep vessels. It also displays temperatures from minus 58ºF to 482ºF. The company says that no glass or mercury is used in the product, and its plastic and stainless steel construction makes it almost unbreakable.
