El instrumento HMA-TMN utiliza detección colorimétrica espectrofotométrica. Primero se añade el reactivo de digestión a la muestra, que después se bombea a la unidad de digestión a alta temperatura. El manganeso total de la muestra se digiere hasta iones de manganeso divalente. En solución ligeramente alcalina, los iones de manganeso divalente reaccionan con la formaldehído-oxima formando un complejo coloreado de color pardo; la medición espectrofotométrica se realiza a 470 nm y el grado de cambio de color respecto al color inicial de la muestra permite determinar la concentración.

Typical Applications:

Surface water, industrial wastewater (such as electrolytic manganese wastewater), online monitoring of total manganese at the inlet and outlet of wastewater treatment plants

Instrument Features:

● Low waste liquid. Waste liquid volume is only 1.8L/month

● Auto range, auto dilution. Both low range and high range modes available

● Automatic backwash sample filter, automatic cleaning before and after each measurement

● Automatic calibration

● 5.7” color LCD touchscreen

● Chinese menu
