The aerator automatic controller recommended to all breeding friends today is based on many years of inspection of similar products and a lot of practical applications and comparisons. And a large amount of first-line data is obtained for everyone's reference.
The main functions of the 325 type aerator controller are as follows
1. Measurement and display function
Measure the dissolved oxygen and water temperature of the pond continuously for 24 hours, and display all the parameters at the same time. Measured dissolved oxygen, water temperature values, and set oxygen limit values; there are also 6 working status indicators.
2; Automatic control function: When the dissolved oxygen in the monitored breeding water is lower than the self-set lower limit, the aerator will automatically start, and when it is higher than the set upper limit, it will automatically stop. When the dissolved oxygen is greater than the high limit, it automatically replenishes oxygen for the lower water body.
3 Manual control functions
Manually start/stop the aerator; according to the local breeding water environment, it can conveniently and flexibly control the start and stop of the aerator,
4 System self-diagnosis machine alarm function:
The instrument self-diagnoses the operating status of the system. Once a fault or power outage, undervoltage, lack of oxygen, etc. is found, the alarm will be immediately displayed, the fault code will be displayed and oxygenation will be forced to start. machine.
Compared with other similar products, the advantages of 325 controller
1. Long service life. The lifespan of pure gold and silver oxygen electrodes can reach 10 years, and the core components have obtained national patents! More than 5 times that of other products.
2. Good stability and performance. It does not exceed the tolerance after 60 days of continuous use, which is more than 20 times that of other products.
3. The measurement distance is long. The longest reach is 300 meters to the center of the pond, the optimal measurement point, which is more than 5 times that of other products. The application effects of 325 aerator automatic controller
1. Save manpower. It eliminates the pain of staying up late on duty, reduces labor intensity, and does not affect normal work during the day.
Second, save electricity bills. Only turn on the oxygenator when necessary, which is scientific and intuitive, eliminating blind oxygenation, using the least amount of electricity to maintain appropriate dissolved oxygen, and avoiding waste of electricity.
Third, ensure safety. The reliability and accuracy of this instrument are much higher than manual control based on experience and feeling. Even if the instrument fails, it can alarm in time and force it to start, which will greatly reduce the possibility and risk of pond flooding!
Fourth, reduce the feed coefficient and increase unit output. The instrument adds oxygen in advance in time, so that fish and shrimps no longer lack oxygen and float, avoiding the phenomenon of "temporary lack of oxygen and floating heads, and only eating for three days will not last long", keeping the fish vigorous, reducing the bait coefficient, the bait utilization rate is high, and the growth rate is improved. This ensures that yields are increased and favorable conditions are created for high-density farming.
Fifth, improve pond water quality and reduce the occurrence of fish diseases. Dissolved oxygen can maintain a reasonable state for a long time. Not only does fish no longer float, but plankton can also survive normally. It can accelerate the decomposition of organic matter, the oxidation of inorganic matter, and inhibit the production, transformation and reduction of ammonia nitrogen, nitrite and hydrogen sulfide. Its content effectively improves pond water quality and greatly reduces the occurrence of fish diseases.
Sixth, significant economic benefits. According to comparative test statistics, compared with the artificial oxygenation method of turning on the aerator after floating the head until dawn, it can save about 30% of electricity and reduce the feed coefficient by about 5-10%. The cost can be recovered in the same year and can create long-term significant benefits. benefit.
