Manufacturer friendly reminder - When selecting a thermostatic bath, the following points should be considered:
1. Firstly, what is the range of temperature required for use? What medium is used as the temperature field carrier, and the medium used varies depending on the temperature range. The medium is generally selected according to the temperature range: ethylene glycol mixed with water (low temperature), alcohol (ultra-low temperature), pure water (5-95 ℃), imported dimethyl silicone oil (suitable for high and low temperatures), etc
2. Choose the appropriate capacity of the constant temperature bath based on your actual situation. The correct calculation method for effective working volume is: the opening size of the working bath plus the bath depth, in millimeters
3. It is a requirement for the temperature uniformity of the constant temperature bath temperature field. Our company divides it into two categories: 1. Ordinary type: ± 0.05 ℃. 2、 Ultra high precision type: ± 0.0020 ℃
4. What is the maximum head of the external circulation function based on the usage situation
