HBCr6+-1 online hexavalent chromium analyzer

HBCr⁶⁺-Type 1 online hexavalent chromium analyzer

HBCr⁶⁺-The Type 1 online hexavalent chromium analyzer automatically completes water sample collection through the control of an embedded industrial computer system. The water sample enters the reaction chamber, and under acidic conditions, hexavalent chromium reacts with diphenylcarbazide to produce a purple red compound, whose color is proportional to the content of hexavalent chromium. The mixed solution after reaction enters the colorimetric chamber, and the voltage related to chromaticity is detected using the photoelectric colorimetric method. After amplification by a signal amplifier, it is transmitted to an embedded industrial computer. After data processing, the embedded industrial computer displays the concentration value of hexavalent chromium and stores, processes, and transmits the data. This instrument is suitable for the determination of hexavalent chromium in surface water and industrial wastewater.

main features

◇ Large screen LCD display

The instrument adopts a large screen LCD display, which can intuitively display the measurement process, measurement results, reports, and measurement result curves.

◇ Storage function

Using a large capacity electronic hard drive, it can store 10 years of historical data (calculated based on 24 data records per day).

◇ Power off protection function

The instrument unexpectedly loses power during operation, but it can automatically restore its original operating state after being powered on again, and the instrument parameters will not be lost after power failure.

◇ Reagent alarm function

After setting the reagent remaining amount, the instrument stops running and alarms when the reagent remaining amount is below the lower limit.
