General Description

The electric thermostatic water bath is a commonly used laboratory device for sample pre-treatment. It is widely applied in medical, chemical, biological fields, as well as in research institutions and laboratories.

The unit consists of an outer housing, a water tank, an electric heating system, and a temperature control system.

Working Principle

The temperature sensor converts the water temperature into a resistance value. After amplification and comparison through an integrated circuit, a control signal is generated to regulate the heating power effectively. This ensures that the water temperature remains constant with high accuracy.

Advantages

• Stainless steel tubular heating elements positioned horizontally.
• Perforated aluminum shelves for stable placement of laboratory containers.
• Top cover with interchangeable concentric rings suitable for different flask diameters.
• Side drain outlet for easy water discharge.
• High-quality temperature control system ensuring precision, reliability, and ease of use.
