The sensor can be combined with the company's two-channel C22 Analyzer to monitor pH, ORP, DO, conductivity, pIon and more. It measures from 0 to 4000 NTU using an IR sensor that emits a beam of 850 nm into a water sample where it is scattered by particles suspended in the water. The amount of light reflected by the particles is correlated to the turbidity or suspended solids, which can be in mg/L, ppm and percent solids to volume. Turbidity measurements (NTU, FNU) are calibrated to the specific user application environment with standards such as Formazin, StablCal or SDVB beads. Accuracy is up to 2 percent of reading or 5 NTU (whichever is larger), with a drift rate of less than 1% per month. The sensor body is constructed with wetted stainless steel and epoxy and operates at pressures up to 50 psi. 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 meters in depth.
