ECD Triton TR6 turbidity sensor

Click2Contact

With advanced optical infrared (IR) sensing and intelligent electronics, the Triton TR6 turbidity sensor from Electro-Chemical Devices (ECD) measures turbidity or suspended solids and can be combined with ECD’s 2-channel C22 analyser to monitor pH, ORP, DO, conductivity, pIon and more.

The sensor measures turbidity or suspended solids in four selectable dual ranges, featuring preset low and high ranges from 0 to 4000 NTU. Its 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. It provides turbidity measurement in mg/L, 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.

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

Featuring a choice of either side- or axially front-mounted optics, the sensor addresses the fact that external reflective surfaces in the emitted light’s range can distort readings.
