Turbidity Analyzer Versatile Optical IR Sensor with Modular Multi-Parameter Measurement
With its optical infrared (IR) sensor and intelligent transmitter, the two channel Triton Turbidity Analyzer from Electro-Chemical Devices (ECD) combines precision turbidity analysis with the flexibility to add a second measurement, including dissolved oxygen (DO), pH, oxygen reduction potential (ORP), conductivity or various pION parameters.
Accurate measurement of turbidity (suspended solids) is important in a wide range of water and wastewater treatment applications: Turbidity is the cloudiness or haziness of a water sample, which is caused by suspended particles in the water that are typically clay and silt. Viruses and bacteria can attach themselves to the particles making turbidity a critical indicator of overall water quality.
ECD’s Turbidity Analyzer is designed with the advanced Triton TR86 Turbidity Sensor and the sophisticated T80 Universal Transmitter. The result is accurate, reliable turbidity measurement with the capability to add one additional measurement parameter, providing plant technicians with the flexibility to add any of ECD’s intelligent S80 plug-n-play sensors to the process control loop.
The TR86 sensor measures suspended solids continuously in a choice of three separate ranges from 0 to 4000 NTU. With its optical IR sensing technology, the TR86 sensor emits an 850 nm beam of near infrared light into the sample where it is scattered by the particles suspended in the water. The amount of back scattered light returning to the sensor is then measured and correlated to the amount of suspended solid particulates in the water.
The measurement response of the TR86 sensor depends on the size, shape and composition of the suspended particles. For this reason, mg/L, ppm and % suspended solids must be calibrated with the monitored water sample. Turbidity measurements (NTU, FNU) can be calibrated with calibration standards such as Formazin, StablCal or SDVD beads.
