First, the appearance of the low temperature thermostat instrument:
Second, the characteristics of the low temperature bath:
1. The low temperature thermostat is cooled by air-cooled fully enclosed compressor, which has the advantages of fast cooling speed and low noise.
2. The refrigeration system has overheating and overcurrent protection devices.
3. Temperature microcomputer intelligent control, simple operation, good temperature stability, upper and lower temperature over temperature alarm, PID automatic control.
4. Double window red and green colors are used, the upper window measurement value is red, the lower window setting value is green, and the LED is displayed.
5. The intelligent microcomputer can correct the deviation of the temperature measurement value and make the digital resolution reach 0.1 °C.
6. The special user PID can be self-tuned.
7. There are internal and external circulation. When the external circulation is used, the constant temperature liquid in the tank can be externally led to establish a second constant temperature field. It can also be used as a cold source (heat source) to lead the liquid in the tank, which can reduce (rise) the outside of the tank. The temperature of the experimental container is extended to the range of use.

Fourth, the low temperature thermostat operation steps:
1. The liquid medium is added to the tank, and the liquid medium level cannot be lower than 20 mm 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 selected from pure water.
C. When the working temperature is 80 ° C - 90 ° C, the liquid medium is generally selected from a water-oil mixture.
D. When the working temperature is between 90 ° C and 100 ° C, the liquid medium is generally selected from oil.
3. Circulating pump connection:
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 with the hose at the inlet of the outer container, and will enter
The liquid pipe is connected to the outlet of the container outside the tank.
4. Plug in the power, turn on the “Power†switch, and turn on the “Cycle†switch.
5. The instrument operates as follows:
A. Instrument button description:
Shift key Addition Subtraction SET Set function key
B. temperature setting:
If the working temperature is higher than the ambient temperature, press the set function key to enter the temperature set value setting state. The last value of the set value flashes. At this time, press the shift key and then press the add value to set the desired working temperature. Then press the set function key and save the set value. At this time, the measurement shows the current liquid in the tank. The temperature of the medium, after which the microcomputer enters the automatic control state.
C. If the working temperature is lower than the ambient temperature, turn on the “cooling†switch and press the set function key to enter the temperature set value setting state. The last value of the set value flashes. At this time, press the shift key and then press the subtraction number to set the desired working temperature. Then press the set function key and save the set value. At this time, the measurement shows the current liquid in the tank. The temperature of the medium, after which the microcomputer enters the automatic control state.
D, other parameters description:
a, SC indicates measurement correction T: indicates time proportional period P: indicates time proportional band
I: indicates the integral coefficient d: indicates the differential coefficient
b. Press the set function key to automatically enter other parameter set value state after 5 seconds. At this time, the measurement window displays “SCâ€, set the required parameters by adding or subtracting, and then press the function key to measure. The value window displays “Tâ€, press the plus or minus key to set the parameters you need, and so on to modify all the parameters, then press the set function key for 5 seconds to return to the normal control state, and save each setting. value.
Note: 1. Set the working temperature and other parameters you need to end, and press again within 15 seconds.
Set the function key to save the set value. If the set value exceeds 15 seconds, the original set value will be automatically restored.
2. Dear users, please do not modify the parameters by yourself. In addition to the measurement value correction, you can modify it.
6. When the measured value reaches the working temperature, compare the temperature difference between the measured value and the actual tank according to the thermometer required for the experiment in the tank. (The operation method is the same as (b) in Article 5D). Experiment or test.
Five, the use of low temperature thermostats:
1. Liquid medium should be added to the front tank.
2. Use the power supply 50Hz 220V, the power supply should be 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 ventilated and dry place with a distance of 300 mm from the obstacle on the back and sides.
4. After use, all switches are turned off and the power plug is unplugged.
