     The constant temperature metal bath is also known as a dry thermostat, which is a metal bath device controlled by a microcomputer to replace the traditional water bath device. It does not have the large temperature fluctuations of the traditional thermostat, which can avoid the traditional water bath. The problem of heating pollution, at the same time, the temperature control is more accurate, and the temperature control range is also larger. A good alternative to traditional water bath devices.

     The thermostatic metal bath is composed of a module and a host. Generally, it is divided into models according to the type, quantity and temperature control range of the modules. Generally, thermostats are divided into heating type and heating and cooling type. The constant temperature metal bath adopts advanced microcomputer control and electric heating film technology, and the product adopts unique temperature control technology; the temperature control is highly precise and stable. The configuration and selection of metal modules of different specifications are suitable for a variety of standard test tubes. The metal modules are easy to replace. Generally speaking, the modules of the same model of various manufacturers are not very different, the main difference is the dry thermostat host.

      First of all, make sure that the constant temperature is only one kind? The constant temperature metal bath is generally divided into heating type, heating and cooling type and heating and cooling oscillation type according to the host, which can be selected according to the purpose of the experiment; Dear.

      Secondly, according to the temperature control range of the dry thermostat host, the temperature control range is usually -10-100°C and -10-150°C. The former is more common, and the latter is rare. When purchasing It can be selected according to the specific application situation. The temperature control range of -10-150 °C is large and the price is more expensive. It is not necessary to choose this kind if it is not so high for general experiments.

       Finally, it is necessary to select the specifications of the module, the most common ones are 0.5ml, 1.5ml, 0.2ml, the processing volume should be selected according to the content and requirements of the test, and the temperature stability should be checked. When the module is heated, the temperature uniformity of each part is the maximum temperature difference of each part, which is generally between 0.1-0.5°C, the lower the better. If the temperature requirements of the experimental reactor are not too strict, you can choose 0.5. The lower the accuracy, the higher the price. The maximum temperature is the highest temperature that the instrument can reach, and it is related to the temperature control range, which is generally 5 to 10 °C higher than the temperature control range.
