Overview
PHDC-1020 Low Temperature Circulating Bath adopts high-performance single-chip microcomputer control, self-tuning PID adjustment and imported temperature sensor, with high temperature control accuracy and low Fluctuation. Using a good refrigeration Compressor, high refrigeration efficiency and low noise; using a good fully sealed stirring motor, low noise and long life. This series is a high-performance High Accuracy model with temperature/time programmable function, accurate temperature control, complete functions, stable and reliable, easy and safe operation.
Features
1. Using high-performance single-chip microcomputer control, PID adjustment, self-tuning control technology, high temperature control accuracy and short Stabilization time.
2. It has a break-even protection function to prevent the instrument from losing control.
3, with liquid level protection device, can effectively prevent various faults caused by heating pipe air burning.
4, with upper limit over-temperature alarm function, can be set by yourself, beyond the range of immediate alarm.
5. The instrument works stably and reliably, making it very convenient to operate.
6, liner, table and all parts immersed in liquid are high-mass stainless steel, corrosion resistance, easy to clean.
7. PHDC series is a high-performance High Accuracy low temperature constant temperature bath, with temperature control accuracy of 0.01 ° C, Fluctuation of 0.01 ° C, Temperature range from -80 ° C to 100 ° C.
8. Adopt professional AI artificial intelligence PID adjustment method, with programmable function of temperature/time (up to 180 program segments).
9. It has the function of communicating with an external computer and enabling reverse control (RS485 interface).
10. The thermostatic test can be carried out directly in the water tank, or the external circulation function can be used to guide the thermostatic liquid in the tank to the Miscellaneous equipment.
Principle
The product is accurately measured and adjusted by a high-performance single-chip microcomputer Control system combined with a self-tuning PID algorithm and an imported temperature sensor. The system controls the refrigeration Compressor to work to achieve cooling, and unifies the liquid temperature in the tank through a fully sealed stirring motor. With internal/external circulation function, it can maintain a constant field source with High Accuracy and uniform temperature in the Tank or through external equipment.
Applications
Bioengineering, Food, Chemical, Metallurgy, Chemical Analysis, Petroleum, Research Institute, Colleges and Universities, Factory Laboratory, Quality control department
Steps
1. Install and place according to the equipment structure (e.g. Floor-Standing).
2. Add an appropriate amount of medium to the Tank.
3. Connect the power supply and turn on the device.
4. Set the required temperature and program through a large-screen backlit LCD screen (DC series) or a digital tube (HDC/PHDC series) (PHDC series can have up to 180 program segments).
5. Start operation, and the device will automatically perform temperature control and adjustment.
6. If external circulation is required, connect the hose to the Miscellaneous equipment and start the external circulation function.
7. After use, turn off the device according to the procedures.
Notice
• Please ensure that the liquid level is normal before use to prevent triggering low liquid level protection or heating tube air burning.
• Pay attention to the set temperature limit to avoid triggering an over-temperature alarm.
• Keep equipment and connecting parts clean, especially stainless steel liners and parts that come into contact with liquids.
• When performing external circulation operations, please ensure that the connecting pipeline is unobstructed and well sealed.
• Do not continue to operate under the alarm or abnormal state of the instrument.
• Follow equipment instructions and laboratory safety regulations when operating.
