Special Parameter Online Monitoring Instrument
Sulfate Online Analyzer
product details

Product model: SO4900




The SO4900 sulfate online analyzer adjusts the acidity and alkalinity of the water sample and adds a characteristic chromogenic agent for colorimetric determination, which can accurately measure the total amount of sulfate in surface water, groundwater, and industrial wastewater.


Measurement Mode


· The content of perchlorate (perchlorate) in surface water and industrial wastewater was measured by color development after enrichment.

· can achieve a variety of choices, timing measurement can be realized every day in any user want to monitor the time to start the instrument for measurement;

· Isochronous measurement can automatically start the instrument for measurement every few hours at a fixed time interval every day;

· Continuous measurement can realize automatic sample measurement one by one, which can be used for product acceptance and related technical certification;

· Manual measurement can realize the user to start the measurement at any time, and can be used for field experiment comparison and equipment installation and debugging;

Measuring Time Can Be Arbitrarily Set

It can ensure that any water sample can react completely, and the setting of measurement time ensures that any water sample can accurately obtain detection results through the instrument.


Flexible Calibration of Standard Solutions

Automatic timing calibration or manual calibration, where the calibration standard solution can be configured and set according to the actual bromate content range of the user’s water sample according to the principle of proximity, because the water sample that the user wants to monitor is generally limited to a certain range. The instrument can adjust the accuracy of the measurement by preparing a standard solution that is close to the actual bromate content of the user’s water sample according to the principle of proximity.


Fuel Injection Pump Long Service Life

The syringe only needs to be replaced once a year.
