1. Scope of application of water-proof constant temperature incubator:
This product is used by the medical and health, pharmaceutical industry, biochemistry, agricultural scientific research and industrial production departments for biological cultivation, storage strains, storage strains, fermentation and other constant temperature tests.
2. Technical index of water-proof constant temperature incubator:
Third, the structure overview of the water-proof constant temperature incubator:
The appearance of the water-proof electric heating constant temperature incubator is vertical. The box body is made of high-quality steel plate and the surface is sprayed with plastic or baked. The water jacket studio is made of stainless steel argon arc welding to make the durability durable. The water jacket structure has accurate and reliable temperature control, without the disadvantage of too thin temperature, the temperature is uniform and it can maintain a constant temperature for a long time after power off. The studio shelf can be easily moved and the shelf height can be changed. The semicircular four corners of the studio are easy to clean. The box door uses a large observation window. It is not necessary to open the door to retreat and clearly observe the culture items in the box. The studio and tempered glass are equipped with Silicone rubber seal can ensure the seal of the studio. The box and the working room are filled with ultra-fine glass wool for heat insulation.
The temperature controller, power switch, and indicator light are all set on the upper part of the incubator. The temperature controller has high temperature control accuracy, and has protection and tracking alarm functions. The water level of the water case has an independent stacking system. If the water level is too low, it will automatically send out an audible and visual alarm.
4. Use method of water-proof constant temperature incubator:
1. Before the incubator fails to power, water must be added at the "water inlet" first, and the water flow of the "water level limit" tube must be stopped. (Put the fittings and water level limit stop tube to prevent water from flowing into the tank)
2. Turn the power switch to "1". At this time, the power indicator light is on, and there is a digital display on the temperature controller that the "water level is normal" indicator is on.
3. Press the setting switch to set the required temperature. After the setting, the heating indicator lights up and starts to enter the heating and heating state. After a period of time, when the temperature is close to the set temperature, the heating indicator flashes and goes out repeatedly. Control to enter a constant temperature state. (Note: Please refer to "Operation Method" for the intelligent temperature controller
4. Open the outer door, put the articles to be cultured into the incubator, and close the door. If the door is opened for a long time, the temperature in the box will fluctuate. This is a normal phenomenon. During the cultivation of the articles, unless the items are placed or taken out It is best not to open the door for a long time to avoid affecting the temperature.
5. If there is too much water, pull out the water pipe under the incubator and let go of some water. If the incubator is not used for a long time, be sure to drain the water in the water jacket through the water pipe, and after each time, Keep the water plug tightly to prevent water leakage.
Fifth, the matters needing attention:
1. When the incubator is used for the first time, water must be added first, and water must be added with clean water. When the low water level is alarmed, water must also be added. There is absolutely no water jacket without water. To prevent the electric heating tube from burning out.
2. The shell of the incubator must be effectively grounded to ensure safe use.
3. The incubator should be placed in a room with good ventilation conditions, and flammable and explosive materials should not be placed around it.
4. The items in the box should not be over crowded, and space must be left.
5. The inside and outside of the box should be regularly serviced to keep clean. Not used for a long time. The water in the water jacket must be drained, covered with a plastic dust cover and placed in a dry room.
Setting function of water-proof constant temperature incubator:
a. Temperature setting: Press the function key, the upper window displays "SP", press the "â–²" "â–¼" key until the number in the lower window is set to the desired value.
b. Time setting: Press the function key, the upper window displays "St", and press the "â–²" "â–¼" key until the lower window number is set to the desired value. If you don't need to set the time, the lower window displays "0".
※ Self-tuning function:
After pressing the "â–¼" key for 20 seconds, the RUN indicator flashes and the meter starts auto-tuning. After the auto-tuning is finished, the RUN indicator turns off, and a group of PID parameters with rapid temperature rise is obtained. The meter is controlled according to the new PID parameters. The new PID parameters can be checked on the meter.
After pressing the "â–¼" key for 20 seconds, the RUN light flashes and the meter starts auto-tuning. After the auto-tuning is finished, the RUN light turns off, and a set of PID parameters that can overcome the overtemperature is obtained. The meter controls according to the new PID parameters. The new PID parameters can be checked on the meter.
During the auto-tuning process, press the "â–²" or "â–¼" key for 20 seconds, the RUN light will go out, the auto-tuning will stop, and the meter will be controlled according to the original PID parameters.
※ Control parameter function:
Press the function key for more than 4 seconds, then press the function key to find LK, press the "â–²" or "â–¼" key to make the lower row display as 18, then press the function key to find the prompt of the control parameter that needs to be adjusted, press " â–² "or" â–¼ "key to make the control parameter display the required value. For the prompts of several control parameters, press the "â–²" or "â–¼" key to make the control parameter display the desired value. Several control parameters can be adjusted at once, then press the function key for more than 4 seconds to return to the standard mode. (Automatically return to standard mode after 1 minute without key press)
Among the control parameters, CL and Ct are invalid parameters, and the adjustment does not change the control effect.
Note: This function has been debugged before the postal plant, generally do not modify it in use.
When using a water-proof constant temperature incubator, remind users: dry burning without water is strictly prohibited. Heating to avoid burning the heating tube; the instrument shell should be properly grounded to avoid accidents; do not turn the instrument upside down to avoid water overflow; in order to reduce scale To produce, it is best to use distilled water. Pay attention to these, the service life of the instrument can be extended.
