Production of digital water bath

The super constant temperature water bath is made of stainless steel plate and precision machining technology, which has the characteristics of high temperature resistance and corrosion resistance. The temperature control device adopts high stability operational amplifier and double integration high-precision A/D conversion technology: designed with far-infrared heating technology, combined with magnetic stirring, the product has short thermal equilibrium time, low temperature fluctuation, good uniformity, LED display, and intuitive. This product is widely used for distillation, drying, concentration, and temperature preservation of chemical or biological products.

The correct operating procedure during use. Add liquid medium into the tank, and the liquid level of the liquid medium should not be lower than 20mm below the worktable. Selection of liquid medium: When the working temperature is below 8 ℃, alcohol is generally used as the liquid medium. When the working temperature is between 8 and 80 degrees, pure water is generally used as the liquid medium. When the working temperature is between 80 and 90 degrees, a mixture of water and oil is generally used as the liquid medium. When the working temperature is above 90 degrees, oil is generally used as the liquid medium. Plug in the power, turn on the "main power" switch, and then turn on the power button and cycle button.

If the working temperature is higher than the ambient temperature, press the setting function key to enter the temperature setting value setting state. The last digit of the set value flashes. At this time, press the shift button first and then press the add button to set the desired working temperature. Then press the set function button and save the set value. At this time, the measured display shows the temperature of the liquid medium in the current tank. After that, the microcomputer enters automatic control mode. Press the setting function key for about 5 seconds, and the word PASS will be displayed on the upper window. At this time, press the plus key to enter the password, and press the setting function key again to enter the actual correction state. At this time, the word SC will be displayed on the upper window. If the temperature is too high, press the plus key, and if it is too low, press the minus key. After the correction is complete, press the setting function key for about 5 seconds to exit. When the measured value reaches the working temperature and stabilizes for a period of time, experiments or tests can be carried out.

How to choose a suitable super constant temperature water bath

1. First, choose the size of the tank that meets your own usage requirements.

2. The temperature range of the super constant temperature water bath also needs to be determined according to the specific requirements of the user.

3. Refrigerant type: Please choose environmentally friendly refrigerants that do not contain fluorine.

4. The parameters of temperature stability and uniformity shall be determined according to the requirements of daily use.

5. Attention should be paid to the selection of cooling bath oil, the appropriate temperature range for use, and the viscosity should not be too high at low temperatures.

6. Safety precautions at low temperatures: Choose a super constant temperature water bath with functions such as ultra-low temperature alarm and low liquid level warning.

7. When the compressor is cooling, it will make noise. When purchasing, it is important to pay attention to the overall noise level of the machine and not affect laboratory use.

8. If connecting other devices from the external circulation, it is necessary to determine the pump pressure and pump power during the external circulation to ensure smooth circulation.

9. When choosing the size of the whole machine, try to choose a smaller model based on power, which can effectively save space. Choose a desktop or a model that can be placed under the experimental table.

10. Checking the cooling power at different temperature points, due to the characteristics of the compressor, it is impossible to always maintain the same cooling power during cooling. The lower the temperature, the lower the cooling power. So when purchasing, pay attention to the temperature point of normal use and see if the cooling power at that temperature point is sufficient for you to use.
