Versatile Turbidity Sensor

May 22, 2012

With advanced optical infrared (IR) sensing and intelligent electronics, the versatile Triton® TR6 Turbidity Sensor from Electro Chemical Devices, Inc., measures turbidity or suspended solids and can be combined with ECD’s two-channel C22 Analyzer to monitor pH, ORP, DO, conductivity, pIon and more. The new Triton TR6 Sensor measures turbidity or suspended solids in four selectable dual ranges featuring pre-set low and high ranges from 0 to 4000 NTU. Its sophisticated optical IR sensor emits a beam of 850 nm (near infrared light) into a water sample where it is scattered by particles suspended in the water. The amount of light reflected back to the sensor by the particles is correlated to the turbidity or suspended solids present in the water. The flexible Triton TR6 Sensor provides turbidity measurement in milligrams per liter (mg/L), parts per million (ppm) and percent solids to volume depending on the size, shape and composition of the suspended solids in the water. Turbidity measurements (NTU, FNU) are calibrated to the specific user application environment with standards such as Formazin, StablCal or SDVB beads.
