Constant Temperature Water Baths & Devices

A constant temperature water tank or constant temperature device is a device that creates a constant temperature regardless of the outside air temperature. A common method is to adjust the temperature of the liquid in the tank with an electric heater to keep the tank at a constant temperature. It is mainly used for experiments and tests, and is used for various purposes such as holding samples at high temperatures such as culturing microorganisms, durability tests for resins, paints, plywood, etc., measurement tests for viscosity and specific gravity, and inspections for thermometers and temperature sensors. will be Many of them are capable of high-precision temperature control of ±0.01°C to ±0.1°C, and some are even equipped with timers, dry heating prevention functions, and sterilization functions, allowing selection according to the application.
