Cr Online Analyzer/ Cr Online Meter, Water Analyzer, Sewage Water Treatment, Waste Water Treatment
This analyzer can automatic continuous work for long-term in an unattended manner. And it is widely used in industrial pollution discharge wastewater, industrial process wastewater, industrial wastewater treatment plants, municipal wastewater treatment plants and so on. Depending on the complexity at the scene, for ensure reliable and accurate testing, can choose different pre-treatment system.
This product uses DPCI (diphenylcarbazide) spectrophotometry colorimetric method. After mixing the water and the regulator, oxidize the Cr3+ to the Cr6+, the Cr6+ and the indicator react to a colored complex, in the acidic environment and the presence of the indicator. The analyzer detects the change of color, converts and outputs the Total Cr value. The amount of the generated colored complex is equivalent to the amount of the Total Cr.
This method is suitable for the waste water, containing of Total Cr within 0~500mg/L.
Suitable for the waste water, containing of Total Cr within 0~500mg/L.
