A constant temperature low-temperature water bath, also known as a constant temperature low-temperature bath, is a constant temperature source that integrates cooling and heating functions, providing a uniform and constant temperature test environment. Its precise temperature control technology and efficient refrigeration and heating system ensure that the set temperature remains stable within a temperature fluctuation range of 0.2 ℃. Easy to operate, using LCD display and touch sensitive buttons, and equipped with multiple safety protection devices to ensure the safety of the experimental process.
