First, the instrument appearance: Second, the characteristics: 1. The high-precision low-temperature constant temperature tank liner and the work table are made of stainless steel and the surface of the chassis is sprayed. 2. The high-precision cryostat refrigeration system adopts air-cooled fully enclosed compressor refrigeration, which has the advantages of fast cooling speed and low noise. 3. The refrigeration system has overheating and overcurrent protection devices. 4. The control system adopts the latest high-precision microcomputer technology, which has the advantages of simple operation, good stability and high precision. 5. The high-precision microcomputer has an over-temperature alarm function inside, and the upper and lower limits of the alarm can be set arbitrarily within 10oC. 6. The high-precision microcomputer can correct the deviation of the measured value, and the special user PID can be self-tuned. 7. The high-precision microcomputer adopts double window, the measured value is red, the set value is green and two colors, LED display. 8. The high-precision microcomputer has a software lock function, which can lock the parameter setting values ​​of the system, and the unrelated personnel cannot change the set parameters. Third, technical parameters: model temperature range (°C) Temperature uniformity (°C) Resolution (°C) Working tank volume (mm3) Work slot opening (mm2) Groove depth (m) Pump flow (L/min) Total power (KW) Voltage (V) GDH-0506 -5～100 ±0.005～0.02 0.01 250x200x150 180x140 150 6 0.8 220 Fourth, the operation steps: 1. Add liquid medium to the tank. The liquid medium level should not be lower than 20mm of the table. 2. Selection of liquid medium: A. When the working temperature is lower than 5 ° C, the liquid medium is generally selected from alcohol. B. When the working temperature is 5 °C~80 °C, the liquid medium is generally pure water. C. When the working temperature is 80 ° C ~ 90 ° C, the liquid medium is generally selected from water and oil mixture. D. When the working temperature is between 90 ° C and 100 ° C, the liquid medium is generally selected from oil. 3, the connection of the circulation pump: A. Connect the inner circulation pump and connect the outlet tube to the inlet tube with a hose (a hose is supplied) B. The external circulation pump is connected to the outer circulation, and the outlet pipe is connected to the inlet of the container outside the tank, and the inlet pipe is connected to the outlet of the container outside the tank. 4. Plug in the power and turn on the “Power†switch. 5. The instrument operation is as follows: A, the instrument button description: B, temperature setting: If the working temperature is higher than the ambient temperature, press the function key to enter the temperature setting value setting state, the setting value window flashes. At this time, press the shift key and then press the plus key to set the required working temperature, and then press the function. The key saves the set value. At this time, the measurement shows the temperature of the liquid medium in the current slot. After that, the high-precision microcomputer enters the automatic control state. C. If the working temperature is lower than the ambient temperature, press the function key to enter the temperature setting value setting state, and the setting value window flashes. At this time, press the shift key and then press the plus key to set the required working temperature. Press the function key and save the set value. At this time, the measurement shows the temperature of the liquid medium in the current slot. After that, the high-precision microcomputer enters the automatic control state. 6. Dear users, please do not modify the parameters under normal circumstances, except for measurement correction. (The internal "SC" of the meter represents the measurement correction). 7. After the measurement reaches the working temperature, check the temperature difference in the actual tank according to the thermometer required to insert into the tank. Stabilize for a period of time to enter the experiment and test. Five, the use of matters needing attention: 1. Add liquid medium to the front tank. 2. Use the working power supply 50HZ, 220V, the power supply is greater than or equal to the total power of the instrument, the power supply must have a good "grounding" device. 3. The instrument should be placed in a dry and ventilated place, and the back and sides should be separated from the obstacle by 300mm. 4. After use, all switches are turned off and the power plug is unplugged. Shanghai Yuming Instrument Co., Ltd.
