As China continues to strengthen environmental protection efforts, the importance of rapid environmental testing has become increasingly prominent. This project addresses issues in traditional environmental testing such as difficulties with on-site sample handling, complex testing procedures, and inconvenience for non-professionals by designing and developing a complete set of rapid environmental testing technologies and portable instruments. These include an internationally unique vector chromaticity meter, a cleverly designed multifunctional sample processing instrument, a unique capsule-packed testing reagent kit, and a lightweight remote control sampling boat. These innovations enable the rapid collection, preprocessing, and quantitative testing of environmental samples in both on-site and field settings.
