Unique injection method. Using a unique pressure-jet injection device, the droplet injection speed is fast, and the instrument response signal and sensitivity are higher. This method avoids the replacement of traditional injection pump injection consumables and the blockage of the metering unit by particles in the water sample.

Reliable pollution resistance. The system has its own pressure flushing function, which can meet the pressure flushing of multiple pipelines, avoiding system pollution or test abnormalities caused by dirty water samples adhering to and blocking the pipelines, greatly reducing the failure rate and instrument maintenance frequency, and meeting the long-term, reliable, and online monitoring needs of complex sewage/wastewater samples.

Integrated structure design. The design of the multifunctional integrated pool can meet the needs of multiple testing functions such as sampling, dilution, aeration, injection sampling, etc., which greatly simplifies the internal structure and testing process of the instrument.

Conventional and gas-saving mode operation. It provides intelligent operation in both conventional and gas-saving measurement modes, saving carrier gas consumption and reducing operation and maintenance costs and labor costs.

Intelligent feedback and judgment. The whole operation process is monitored, and the working mode, the status information of key instrument components, and the information of auxiliary equipment are monitored in real time. It greatly improves the unmanned and off-site operation of the equipment and obtains excellent stability and reliability.
