Low Temperature Cooling Liquid Circulator 6L
DC series low temperature constant temperature tank is controlled by single chip microprocessor, self-tuning PID adjustment, imported temperature sensor temperature measurement, high temperature control accuracy, low volatility; high quality famous brand compressor (some models are all imported compressors or compressors), high refrigeration efficiency, fast cooling and low noise. The instrument is stable and reliable, and the operation is convenient and safe.
It is widely used in the fields of biological engineering, medicine, food, chemical industry, metallurgy, chemical analysis, oil and the like, and provides a constant field source with high precision, controlled and uniform temperature for users, and is an ideal constant temperature device for research institutes, colleges and universities, factory laboratories and quality inspection departments.
1. The machine adopts microcomputer based temperature control. High accuracy of temperature control.
2. Intelligent digital system can correct the deviation of the temperature measurement, which make the digital resolution 0.1℃.
3. The refrigeration system has over-heating and over-current multiple protective function.
4. The machine has intelligent instrument control, which easy to operate and of high temperature stability. It is also has alarm function when the temperature reach the upper and lower limitation.
5. Equipped with fully efficient anti-interference compressor.
6. Cooling rate is faster than similar products, lower noise, lower vibration.
1．Remove the package, do a good job of cleaning, put on the solid worktable.
2．A sufficient amount of liquid medium is added to the tank so that the distance between the liquid level of the medium and the working table is less than 3 cm. If the amount of liquid poured into the tank is too small, the low liquid level prompt flashes when turned on, accompanied by alarm sound.
3．Connecting the circulating pump to the water outlet pipe.
(1) When the circulating pump does not need external circulation, just use the hose to connect the inlet and outlet.
(2)When the circulating pump needs constant temperature liquid external circulation, two hoses are used to connect the "outlet" tube with the inlet of the external experimental container, and the "inlet" tube and the outlet pipe of the external experimental container can be connected. Note: be sure to connect the inlet pipe with the outlet pipe before turning on the power supply.
4. Turn on the power supply and turn on the power switch of the rear cover.
At this time, the liquid crystal display screen will display all the symbols to enter the self-test, and the temperature input range will be displayed after 3 seconds (upper row: PV is displayed as the upper limit value of the input temperature, lower row: SV is displayed as the lower limit value of the input temperature), and after the self-test passes, the PV will be displayed as the actual temperature of the liquid in the slot, and the SV will be displayed as the temperature set last time.
5. Set temperature.
It is suggested that the refrigeration opening logic should be satisfied: both PV and SVvalues are less than 41 ℃ and the refrigeration function is turned on more than 5 minutes before the compressor is shut down last time, on the contrary, the refrigeration output is turned off.
2. No vibration and no harmful gas.
3. Ambient temperature should be less than 30°C and relatively stable, cannot be high and low, affect the temperature control accuracy.
4. The ambient humidity should be less than 80% and the humidity is too high. When the constant temperature tank is working at low temperature, the compressor may dewing.
2. The selection of liquid media in the tank shall conform to the following principles:
⑴When the working temperature is lower than 5 ℃, absolute ethyl alcohol or ethylene glycol is used for the liquid medium.
⑵When the working temperature is 5 ℃ ~95 ℃, water is generally used in liquid medium.
⑶When the working temperature is between 95 and 100 ℃ , a 15% aqueous glycerol solution can be used for the liquid medium.
Note: The operating temperature here is the temperature to which the liquid medium in the tank is to be reached;
3. Power supply:110V, the power of the power supply shall be greater than the total power of the instrument, and the power supply must have good "ground" device；
4. Because the refrigeration compressor works continuously (refrigerator, air conditioning is intermittent), it needs to be shut down for a day after a long period of continuous work (such as about 5 days).
5. The instrument should be placed in a dry and ventilated place, and there are no obstacles in the 300mm around the instrument.
6. When the working temperature of the thermostatic bath is lower or higher, care should be taken not to open the upper cover, and do not enter the tank to prevent frostbite or scald.
7. After the use, all the switches are put in the closed state and the power is cut off.
8. The instrument should do a good job of regular cleaning and keep the working table and operation panel clean and tidy.
9. Pay attention to the level of the liquid level in the observation tank. When the liquid level is too low, the liquid medium shall be added in time.
