Intro to MEJ-DO7011 Membrane dissolved oxygen sensor
The MEJ-DO7011 membrane dissolved oxygen sensor performs well in measurement accuracy, stability, and other aspects. The following elaborates on its advantages from different dimensions:
High precision measurement:
By using the principle of polarographic measurement, it is possible to accurately determine the dissolved oxygen content of 0-20mg/L (or 0-20ppm) in aqueous solutions, with a resolution of ± 3% of the measured value, providing reliable data for water quality analysis.
Wide range and strong environmental adaptability:
The measurement range of dissolved oxygen is wide, and it can adapt to water temperature environments of 0-45 ℃. It can work normally under various water conditions and is suitable for monitoring complex natural water bodies or industrial environments.
Stable and reliable:
The sensor design and working principle enable it to have good stability, resist interference from some impurities in water, continuously output stable dissolved oxygen data, and reduce measurement fluctuations and errors.
Standard signal output:
Adopting a 4-20mA standard current signal output, it is easy to directly connect with various display instruments, control systems, or data acquisition devices, with strong compatibility, and is conducive to building a complete monitoring system.
Temperature compensation function:
Built in temperature detection components (optional NTC 10k or PT1000) can monitor water temperature in real time and compensate for measurement errors caused by temperature changes, further improving measurement accuracy.
Widely applicable scenarios:
Suitable for multiple fields such as water quality monitoring, aquaculture, and industrial process water monitoring. In aquaculture, real-time monitoring of dissolved oxygen in aquaculture ponds can assist farmers in scientific management; In industry, it can be used for dissolved oxygen detection in sewage treatment plants, boiler water and other scenarios.
Easy maintenance:
Reasonable structural design facilitates daily maintenance and calibration, reduces long-term usage costs, and ensures the continuous and stable operation of sensors.
