Special Parameter Online Monitoring Instrument
Formaldehyde Online Analyzer
product details

Product Model :HCHO-8000


Measurement principle


Optical colorimetric method,Real time measurement of formaldehyde content in water.


Systematic Review


HCHO-8000 Formaldehyde online analyzer is a fully automatic analyzer controlled by embedded system, which can be applied to real-time online monitoring of formaldehyde content in various water quality. After the sample is filtered, it is pumped into the reactor, the masking agent is injected first to eliminate the interfering substances, and then the acidity of the solution is adjusted to make the solution have a suitable pH, and then the characteristic color developer is added to react with formaldehyde in the water for color development, and the absorbance of the reactants is measured. The content of formaldehyde in the sample is calculated by the size of absorbance.
