A temperature calibration bath is a calibrator having a uniform fluid enclosure that can be adjusted to specific temperatures for test points. They offer large volumes and flexibility for calibrating temperature sensors that are different shapes and sizes. These units utilize a liquid as the calibration medium as they perform sensor and precise thermometer testing. The liquid is cooled or heated to reach and maintain a certain temperature. Our products include lab-grade and deep-well baths, as well as compact and micro baths. Deep well baths can calibrate long PRTs and SPRTs. They also serve as liquid-in-glass thermometer baths. A water bath is laboratory equipment made from a container filled with heated water. It is used to incubate samples in water at a constant temperature over a long period of time. Most water baths have a digital or an analog interface to allow users to set a desired temperature, but some water baths have their temperature controlled by a current passing through a reader. Utilization includes warming of reagents, melting of substrates or incubation of cell cultures. It is also used to enable certain chemical reactions to occur at high temperatures.
