GENERAL INFORMATION
Product Description
The MPA-48 Multi-Parameter Analyzer comes standard with 4 channels for the continuous
measurement of dissolved oxygen, suspended solids, pH and/or ORP in an aqueous solution. It can be
easily upgraded to handle up to 8 channels with the addition of daughter boards and sensors. The
microprocessor-based electronics of the MPA-48 analyzer provide a high degree of flexibility and ease of
use. The instrument is designed to operate with any combination of InsiteIG sensors in a variety of
applications. The DO sensor to be used with this analyzer is an optical type sensor that measures the
fluorescence and quenching reactions of a ruthenium complex that is immobilized in a sol-gel matrix.
The SS sensor operates on the principle of single gap light absorption as a means of detecting the
presence of suspended solids. The pH and ORP sensors are flat glass electrodes.
The Model 10 Dissolved Oxygen sensor is designed for the continuous monitoring of dissolved
oxygen in water and wastewater where parts per million accuracy is required. The unit will display
dissolved oxygen content in PPM, mg/l or %SAT. The resolution in PPM and mg/l mode is 0.01 over a
range of 0.00 to 3.99 and 0.1 over a range of 4.0 to 25.0. The resolution in %SAT mode is 0.1%SAT
over a range of 0.0 to 99.9%SAT and 1%SAT over a range of 100 to 400%SAT. Temperature is
displayed in 0.1 degree Celsius increments over a 0.0 to 50.0 degree Celsius range or 1 degree
Fahrenheit increments over a 32 to 122 degree Fahrenheit range. It incorporates self-cleaning optics via
air or water jet.
The Model 15 TSS sensor has been designed for medium ranges (0 to 30,000 mg/l) as commonly
found in aeration basins of wastewater treatment plants and comes in pipe insertion configurations. The
Model 15L sensor has been designed for low ranges (0 to 1500 mg/l) as commonly found in effluent
streams. Both sensors utilize an infrared emitter to minimize color effects and compensates for emitter
variations due to temperature by measuring source brightness. They incorporate self-cleaning optics via
air or water jet.
The Model M50 is a microprocessor based preamp interface for the M51 and M52, pH and ORP
electrodes (please specify pH or ORP when ordering the M50). The unit will display the pH value in 0.01
pH resolution over a range of zero to 14.00 pH. However, the pH electrode is only rated for a pH range
of 2 to 12. The unit will display the ORP value in 1 mV resolution over a range of -2000 to 2000 mV.
Water temperature may also be measured for automatic temperature compensation. The temperature
may be displayed in degrees Celsius or degrees Fahrenheit. Temperature is displayed in 0.1 degree
Celsius increments over a 0.0 to 50.0 degree Celsius range or 1 degree Fahrenheit increments over a 32
to 122 degree Fahrenheit range. They incorporate self-cleaning via air or water jet.
Packaging
The analyzer is housed in a NEMA 4X enclosure (see Drawing IIG07N111 for Outline and Mounting)
and is designed for outdoor mounting. For areas where the environmental temperature is expected to
drop below 14 degrees Fahrenheit (-10 degrees Celsius) for extended periods of time, the optional
automatic heater assembly is recommended.
