Product Description

Product Description

Digital Display Constant Temperature Water Bath

The digital display constant temperature water bath is a commonly used laboratory device designed for precise temperature control of liquid samples. It is widely applied in biochemical, medical, and chemical industries for processes such as constant-temperature heating, evaporation, and drying. Below is a detailed introduction to this equipment:  

Main Features  

 Digital Display & Control* 
- Equipped with a microprocessor control system and an LED/LCD screen to display real-time and target temperatures for intuitive operation.  
- High temperature adjustment accuracy (typically ±0.1°C to ±0.5°C) with a broad temperature range (ambient temperature to 100°C or higher, depending on the model).  

 Uniform Heating  
- Features a stainless steel chamber heated by electric heating tubes, with some models including a stirrer to ensure even water temperature distribution.  

Safety Protection Functions  
- Over-temperature alarm, dry-burn protection, and leakage protection to ensure stable operation during prolonged use.

FAQ

Digital Constant Temperature Water Bath

1. How much water should I add before turning on the water bath? 
   - Before powering on, fill the bath with water above the partition plate (at least covering the heating element). Never operate with the heating tube exposed, as this may cause overheating, tube rupture, solder melting, leakage, or electric shock.  

 2. Can I use this water bath for boiling at 100°C?  
   - Yes, but **do not overfill** the bath to avoid boiling overflow. For prolonged boiling, monitor the water level to prevent evaporation-related issues.  

3. What power supply does this device require?
   - The water bath operates on **220V AC** and must be connected to a grounded 3-pin safety socket for proper earthing and electrical safety.  

 4. What should I do if there's an electrical malfunction? 
  Do not attempt DIY repairs.** Only qualified technicians should handle wiring or internal component issues to prevent hazards.  

 5. How do I safely move the water bath or add liquids?  
   - Turn off and unplug** the device before moving it. When adding liquids (e.g., water or oil), do so carefully to avoid spills, burns, or electrical accidents.  

6. What is the temperature stability and accuracy?  
   - Temperature fluctuation: ≤±0.5°C  
   - Control accuracy:≤±0.5°C  
   - Resolution: 0.1°C

7. Can I use oil instead of water for higher temperatures?  
   - This depends on the model. Standard models (e.g., HH series) support **water bath only (up to 100°C). For higher temperatures, check if your model is compatible with oil baths (e.g., silicone oil).  

8. How do I clean and maintain the water bath?  
   - Regularly replace water to prevent scaling. Use distilled water or descaling agents (e.g., diluted acetic acid).  
   - Drain completely when not in use to avoid corrosion.  

9. Why is my water bath not heating properly? 
   - Check if the heating tube is fully submerged.  
   - Ensure the power supply is stable and the socket is grounded.  
   - If issues persist, contact technical support.  

**10. What safety features does it have?  
   - Over-temperature protection, anti-dry burn protection, and grounded power design.
