JPBJ-611Y portable optical dissolved oxygen Tester, the dissolved oxygen sensor supporting the instrument can be well adapted to the field application environment, its structure and use mode is close to the online sensor, with the advantages of solidity, sturdy, anti-falling off. The instrument can directly throw the dissolved oxygen electrode into the river for detection, which effectively avoids avoiding water quality changes in the process of sampling and sample delivery.
In addition, the instrument adopts the new fluorescence dissolved oxygen measurement technology, which does not require polarization, does not need to replace the diaphragm and electrolyte, reduces the maintenance workload, improves reliability, and is especially suitable for on-site detection in the field such as lakes, pollution sources, fish ponds, and marine testing.
● 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, the water sample needs to be brought to the laboratory for analysis and measurement, and the monitoring period is long, and the monitoring results have a lag, which cannot reflect the changes of water pollution in a timely and accurate manner.
● Using fluorescent dissolved oxygen measurement technology, there is no need to replace the diaphragm and electrolyte, it is not affected by flow rate, stirring environment, chemical substances and other factors, and has strong anti-interference ability, no polarization, stable measurement and easy to use.
● The instrument adopts the new microprocessor technology and uses a 3.5' TFT touch screen, which has high light transmittance, which is especially suitable for field use.
● Powered by lithium battery, it greatly prolongs the use time and experience of the instrument. Compared to instruments powered by alkaline batteries, the user experience is improved by eliminating the need to frequently disassemble the chassis and replace the battery.
● Allows measurement of dissolved oxygen concentration, dissolved oxygen saturation and temperature value;
● Support electrode correction function, users can correct zero oxygen and full degree.
● Support automatic compensation of atmospheric pressure.
● Support measurement section ID management, allowing users to create up to 30 measurement sections.
● Support GPS function, the measurement result contains the position information of the measured section.
● The instrument supports the storage of up to 1000 sets of measurement results, and each measurement result contains the following information: measurement section ID, measurement time, operator, GPS information, measurement results, electrode correction information.
● Support to check the storage results, support a variety of access conditions, according to the measurement section ID, according to the section name, storage number, storage time, operator ID, etc., the query results are displayed in the form of curves.
● The instrument supports firmware upgrade function, allowing the instrument function to be expanded and personalized requirements.
● The instrument has a power-off protection function and supports low-power management functions, including automatic backlight adjustment, automatic shutdown and other functions to save power consumption.
