Measurement
Measurement method
Combined multiple-beam alternating light technique with IR diode system and beam
focusing
Turbidity (TRB)
2-channel 90° scattered light measurement in accordance
with DIN/EN 27027/ISO7027, wavelength = 860 nm
additional measurement value verification through
eight-channel multiple-angle measurement
Solid matter (TS)
Modified absorption measurement:
Eight-channel multiple-angle measurement,
wavelength = 860 nm
Air-bubble compensation Software-based
Measurement value
