product details

Product model: T8000-ph




4-aminoantipyrine photoelectric colorimetric method.


Measurement Method


· 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;


System description


The T8000-ph online phenol analyzer in water is a fully automatic online monitoring instrument controlled by an embedded system, which can be applied to various water quality such as river water, surface water, and industrial wastewater. After the sample is filtered, it is pumped into the reactor. First, a masking agent is injected to eliminate the interfering substances. Then, the pH value of the solution is adjusted to make it have a suitable pH value. Then, a characteristic chromogenic agent is added to react with phenols in water, and the absorbance of the reactant is measured; Calculate the concentration of phenol in the sample through the absorbance value and the correction factor stored by the monitor.
