A tubular stainless steel heater is positioned horizontally within the constant-temperature water bath, and a perforated aluminum shelf is placed inside the tank.
The top cover is fitted with concentric rings of various diameters to accommodate flasks of different sizes. A drain pipe is located on the left side of the unit, while the electrical control box is situated on the right; the front panel of this box houses the temperature controller and the power switch. The control box contains the heating element and the temperature sensor. The temperature control system utilizes high-quality electronic components, ensuring sensitive temperature regulation, reliable performance, and ease of use.
Its operating principle is as follows: a Cu50 sensor converts the water temperature in the tank into a resistance value. After the signal is amplified and compared via an integrated amplifier, a control signal is output to effectively regulate the average heating power of the electric heating element, thereby maintaining a constant water temperature. Water bath heating is suitable when the object being heated requires uniform heating and a temperature not exceeding 100°C. These baths are typically constructed from copper or aluminum and feature a series of concentric rings to accommodate vessels of various sizes. Care should be taken to prevent the bath from boiling dry and to avoid using it as a sand bath.
