Turbidimeter Probe Model TURBImat-LC


The turbidimeter probe model TURBImat-LC measures the NIR- absorption caused by turbidity in liquids.
Measurements from medium-low up to medium trubidity ranges.

Configurable to measure:

ppm, mg/l, EBC, FTU, g/l, %, AU, Ext, OD, ….

Measuring principle Turbidimeter Probe


The probe uses the principle of NIR- absorption to detect turbidity in liquids. An LED light source with emission in the near-infrared range and a high-precision receiver diode are installed in the sensor’s optics.
The measurement in the infrared spectrum ensures precise measurement results, unaffected by fluctuations in product color.

Calibration / maintenance interval typically 12 months (depending on application):
– Less maintenance and longer service life.
– Service life of the LED light sources, typically 5 years.
– Alternative full spectrum Vis- Lamp, service life typically 1 year.
– Inbuild cleaning jets for sight glass cleaning without mechanicle wipers.
Turbidimeter Probe material typically stainless steel 1.4404 (optional titanium, Hastelloy, …):
