SS400G MLSS Converter
Brand: Yokogawa Electric Corporation
The Model SS400 MLSS Analyzer is a measuring system best suited to continuously and consistently measure the concentration of mixed liquor suspended solids (MLSS) in an activated-sludge treatment process found in sewage or industrial wastewater treatment facilities.
The analyzer consists of an MLSS sensor comprising light emitting and photodetector units, an MLSS converter with a digital display for instant recognition of readings, and one of several types of holders.
Designed to be more lightweight and compact for easier handling when compared with conventional equipment, the analyzer also has a construction that allows easy system maintenance.
The SS400G MLSS converter has a measuring range as wide as 500 to 20,000 mg/L (ppm).
Microprocessor based, it has a wealth of self-diagnostic functions and alarm contact outputs like other converters in the EXA series, as well as excellent operability.
A self-cleaning floating holder is available in addition to free-standing and immersion models, offering a wide range of choices according to the application needs.
