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

Description

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
