ECD Triton TR82 turbidity sensor

Click2Contact

The Triton TR82 from Electrochemical Devices is a nephelometric turbidity sensor designed for use in water and wastewater. The Triton TR82 uses an optical method for determining the turbidity, in which a light beam is directed into the sample where it is scattered by suspended particles in the water. The amount of scattering depends on the amount of material in the water, the wavelength of light, and the size and composition of the suspended particles.

The Triton TR82 uses a near infrared LED light source and the 90° scattered light method in accordance with ISO 7027/EN 27027 to assure accurate turbidity values under standardised and comparable conditions.

The TR82 response depends on the size, shape and composition of the suspended particles. For this reason, mg/L, ppm and % solids measurements must be calibrated with suspended solids from the waters to be monitored. Turbidity measurements (NTU, FNU) can be calibrated with calibration standards such as Formazin, StablCal or SDVB beads.

The Triton TR82 sensors are designed to work with the T80 transmitter. The T80 is a single or dual channel transmitter with one or two 4–20 mA outputs with Modbus RTU and three optional alarm relays or HART 7 communication.

Designed for use in environmental water, the Triton TR82 is suitable for most aqueous applications. It is not suitable for use in organic solvents or in solutions with an extreme pH value, but between 2 and 12 pH.
