MJ-WQA500 – Submersible Water Quality Analyzer

MJ-WQA500 is designed and developed by MJ Instruments to be a submersible water quality analyzer.

Due to its compact size, it can be deployed on a buoy in the reservoir or open sea.

A removable reagent compartment allows user to easily replace the reagent, reducing maintenance time and minimizing chances of cross-contamination.

With its IP68 housing, it is suitable for long-term deployment. Multiple parameters can be customized into a single MJ-WQA500.

Data stability and reliability are enhanced by quality components.
