Introduction: JPBJ-611Y Portable Optical Dissolved Oxygen Tester. The dissolved oxygen sensor of the instrument can be well adapted to the field application environment. Its structure and use method are close to the online sensor. It has the advantages of sturdiness, sturdiness, and anti-shedding. The instrument can directly throw the dissolved oxygen electrode into the river channel for detection, effectively avoiding water quality changes during sampling and sample delivery. In addition, the instrument uses a new fluorescence method of dissolved oxygen measurement technology, no polarization, no need to replace the diaphragm and electrolyte, reduce maintenance workload, improve reliability, especially suitable for lakes, pollution sources, farming ponds, Field testing in the wild, such as marine testing. Features: 1. The instrument allows on-site measurement, adapts to the requirements of modern surface water, especially urban river water quality protection, and the measurement data is real-time, timely and accurate. It is not necessary to follow the traditional method. It is necessary to take the water sample to the laboratory for analysis and measurement. The monitoring period is long, and the monitoring results are lagging, which cannot reflect the changes in water quality in a timely and accurate manner. 2. Adopt fluorescence method dissolved oxygen measurement technology, no need to change the diaphragm and electrolyte, not affected by factors such as flow rate, stirring environment, chemical substances, etc. It has strong anti-interference ability, no polarization, stable measurement and easy to use. 3. The instrument adopts a new microprocessor technology and uses a 3.5’TFT touch screen, which has a high light transmittance and is particularly suitable for field use. 4. The use of lithium battery power supply greatly prolongs the use time and experience of the instrument. Compared with instruments powered by alkaline batteries, you can avoid frequent disassembly of the case and battery replacement, which improves the user experience. 5. Allow measurement of dissolved oxygen concentration, dissolved oxygen saturation, temperature values; 6. Support electrode calibration function, users can calibrate zero oxygen and full scale. 7. Support automatic compensation of atmospheric pressure. 8. Support measurement section ID management, allowing users to create up to 30 measurement sections. 9. Support GPS function, the measurement result contains the position information of the measurement section. 10. The instrument supports storing up to 1000 sets of measurement results, each measurement result contains the following information: measurement section ID, measurement time, operator, GPS information, measurement results, electrode correction information. 11. Support to check the storage results, support a variety of search conditions, can be checked according to the measurement section ID, according to the section name, storage number, storage time, operator ID, etc. The search results are displayed in a curve. 12. The instrument supports firmware upgrade function, allowing instrument function expansion and personalized requirements. 13. The instrument has a power-off protection function, supports low power consumption management functions, including automatic backlight adjustment, automatic shutdown and other functions to save power consumption.
