1. The constant temperature water bath should be placed on the fixed platform. The power supply voltage must match the voltage required by the box. The power socket should use a three-hole safety socket. The ground wire must be connected before use.
2. Before the experiment, according to the experimental requirements, add an appropriate amount of water or purified water to the water tank to the partition or higher. The test vessel is then placed on the shelf and the hole cover is covered.
3. Turn on the power, set the power switch to the "ON" end, turn the temperature "set-measure" switch to the "measurement" end, the green light is on, the power supply is normally heated, and then the temperature setting knob is turned according to the desired temperature to perform the temperature. The setting, at this time "LED" shows the set temperature value, when the set temperature is higher than the water temperature of the sink, the instrument starts to heat up. When the green light is on, the heater starts to heat up. When the red light is on, the heater stops heating. The traffic lights alternately jump to indicate that the temperature is constant. If you need to change the temperature, turn the setting knob at any time. When using, the temperature displayed by “LED†is the actual required temperature.
4. Turn the temperature “set-measure†switch to the “measurement†end. The system automatically measures the temperature of the reagent in the water tank. At this time, the temperature displayed by “LED†is the actual required temperature.
Constant temperature water bath maintenance:
1. Clean the instrument immediately after each use.
2. After each use, the water in the constant temperature water bath is cleaned, and the coarse impurities in the constant temperature water bath are lightly brushed off with a brush, and the pot is removed. Wipe the inner and outer surfaces of the constant temperature water bath with a soft cloth, and then dry with a cleaning cloth.
3. Effect evaluation: The inner surface of the device should be free of water, and the outer surface of the device should be bright and tidy, without smudging.
4. When the constant temperature water bath is used, it must be grounded reliably, and the water should not overflow into the control box.
5. Do not use water or water level below the electric heating tube in the constant temperature water bath to prevent the electric heating tube from being damaged.
6. Perform maintenance inspection of the instrument once a month and fill in the maintenance record in time.
Working principle of constant temperature water bath, operation and maintenance and application field
The working principle of constant temperature water bath:
A stainless steel tubular heater is placed horizontally in a constant temperature water bath, and an aluminum shelf with a hole is placed inside the sink. The upper cover is equipped with a combination of different calibers to accommodate flasks of different calibers. There is a water discharge pipe on the left side of the constant temperature water bath. The right side of the constant temperature water bath is an electric box. The front panel of the electric box is equipped with a temperature control meter and a power switch. There are electric heating pipes and sensors in the electrical box. The temperature control system uses high-quality electronic components, sensitive temperature control, reliable performance and easy to use. The working principle: The Cu50 sensor converts the temperature of the water in the water tank into a resistance value. After amplification and comparison by the integrated amplifier, the control signal is output, and the average heating power of the electric heating tube is effectively controlled, so that the water in the water tank is kept at a constant temperature.
Constant temperature water bath operation :
Constant temperature water bath application areas:
The constant temperature and constant temperature water bath is widely used in drying, concentrating, distilling, impregnating chemical reagents, impregnating drugs and biological products, and can also be used for constant temperature heating and other temperature tests in water baths. It is a biological, genetic, viral, aquatic, environmental, medical, health, and biochemical experiment. Room, an essential tool for education and research
Stainless steel constant temperature water bath is an indispensable tool for the chemical industry, colleges and universities, scientific research and environmental protection, petrochemical, printing and dyeing, mining and other industries to carry out distillation, drying, concentration and constant temperature heating of chemicals and biological drugs.
