The Triton TR8 Analyzer is available with immersion fittings for service in the aeration basin or insertion fittings for the return and waste activated sludge lines. The product is used to measure suspended solids or turbidity at levels greater than 500 NTU, with output available in multiple units: 0 to 9,999 FNU, 0 to 9,999 ppm, 0 to 300 g/l and 0 to 200%. The unit features an error rate of less than 5% of reading with repeatability greater than 1% of reading. The system features a multi-beam optical assembly. The first light beam is a reference detector that compensates for changes in the LED light source caused by aging or other variables. The second light beam detects the short path length, which is best of high concentration measurement. The third light beam measures the longer path length, which is best suited for lower concentrations.
