TGH-SCr Hexavalent chromium/chromium total water quality on-line automatic monitor


Instrument is introduced
TGH - SCr hexavalent chromium/chromium total water quality on-line automatic monitor using diphenyl 2 hydrazine spectral colorimetric method to determine carbonyl, according to the scene setting unattended automatic continuous work for a long time, depending on the complexity of the working condition of field test, optional corresponding pretreatment system, to ensure that the test results are accurate and reliable process, fully meet the requirements of different occasions.
This method is suitable for the hexavalent chromium in waste water within the scope of 0 ~ 30 mg/L, after preprocessing and adjust the measurement process Settings can also be very low and very high levels of total chromium, suitable for rapid analysis of rivers and lakes water, tap water, waste water, high concentration of sewage, and various of hexavalent chromium/total chromium content in the solution.
The performance characteristics of
Principle of mixer instrument detection using national standard method, test process completely in line with industry standards
Mixer simple maintenance, low operating cost
Convenient maintenance, low failure rate and long life
Mixer automatic calibration and cleaning
Pieces of data stored records will never be lost
Components and energy saving, no secondary pollution
Mixer automatic alarm, automatic diagnosis and automatic eliminate residual reactants and automatically return to work
