turbidity sensor

Electro Chemical Devices has announced the Triton TR6 Turbidity Sensor, which measures turbidity or suspended solids and can be combined with ECD’s two-channel C22 Analyser to monitor pH, ORP, DO, conductivity, plon and more.

The sensor measures turbidity or suspended solids in four selectable dual ranges featuring pre-set low and high ranges from 0 to 4000 NTU. Its optical IR sensor emits a beam of 850nm (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 sensor provides turbidity measurement in milligrams per litre (mg/L), parts per million (ppm) and per cent 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.

Designed for demanding environments, the sensor is temperature compensated to achieve accuracy of up to 2 per cent of reading or 5NTU (whichever is larger), features a drift rate of less than 1 per cent per month and operates at pressures up to 50psi. The sensor body is constructed with wetted stainless steel (AISI 316 Ti) and rugged epoxy. The process connection is a 1-inch NPT Nylon fitting and features an optional waterproof cable. It can be installed in either an inline flow cell or submersible configuration up to 500 metres in depth.
