Refrigerated And Heated Circulator Bath,1

1. Intelligent PID Control Unit: The PID temperature control system can be automatically searched or manually adjusted, featuring stronger temperature stability. The temperature correction function can reach 0.01 ℃.
2. PT100 Temperature Sensor: The heating tube is fabricated from SUS304 stainless steel, and the PT100 three-wire system ensures more accurate temperature measurement.
3. Copper Core Motor Circulation Pump: The pure copper core motor, with rotor processed by CNC gear grinding, enables rapid circulation, is stable and low-noise, effectively guaranteeing temperature uniformity.
4. Internal Circulation Mode: Connecting the water inlet and outlet of the thermostatic bath with a single hose is termed as internal circulation.
5. External Circulation Mode: External circulation can extract the constant-temperature liquid within the bath to the exterior to establish a second constant-temperature field. It can also serve as a cold source to guide the refrigerated liquid inside the bath to the external experimental container for easier cooling.

Working Environment Conditions:
1. Adequate Ventilation: Ensure a free flow of air around the equipment to avoid heat accumulation.
2. Absence of Corrosive Gases: Avoid usage in environments containing corrosive gases such as acids and alkalis to prevent equipment damage.
3. Free from Strong Electromagnetic Interference: Stay away from strong electromagnetic fields to evade influencing the electrical system of the equipment.
4. Flat and Stable Ground: The ground where the equipment is placed should be level and stable to prevent the equipment from tilting or swaying.
5. Stable Power Supply: Provide a stable power supply that complies with the equipment's requirements to avoid voltage fluctuations.
9. No Direct Sunlight Exposure: Prevent direct sunlight from shining on the equipment to avoid excessive surface temperature.

Precautions:
1. Equipment Inspection: Before usage, check whether all components are intact, and verify that the liquid level and air pressure are normal.
2. Grounding Safety: Ensure reliable grounding of the power supply. Do not operate when hands are moist.
3. Stable Placement: After adding liquid, avoid transporting or tilting the equipment. When discharging liquid, it should be conducted at room temperature.
4. Medium Selection: Utilize a heat transfer medium that is non-corrosive, non-flammable, non-explosive, and non-volatile.
5. Protecting the Circulation Pump: Do not activate the circulation pump when there is no heat transfer medium.
6. Hose Inspection: Ensure that externally connected hoses are firmly attached and avoid sharp bends.
7. Fault Handling: In the event of equipment damage or leakage, disconnect the power supply prior to undertaking repairs.
8. Avoid Shaking: During usage, prevent the equipment from shaking or undergoing elevation and descent.
