The DTS-12 is a turbidity and temperature sensor designed specifically to deliver high accuracy results from a sensor that can be easily field-deployed and requires very little maintenance.

The sensor features a 12-month recalibration interval and a built-in silicon wiper blade which helps minimize biofouling, helping to ensure accurate sampling from 0 to 1,600 NTU. The DTS-12 meets the quality standards of the USGS and has received their approval for in-situ turbidity monitoring.

Advanced Sensor Technology

In order to provide quality turbidity data, the DTS-12 takes 100 readings over five seconds, then computes and outputs the mean, variance, median, min, and max values. This statistical analysis compensates for entrained debris spikes and “cleans” the data, providing a precise measurement of bulk turbidity.

The DTS-12 uses Nephelometric geometry calculations to improve the signal-to-noise ratio by measuring the forward and back scattered light at a 90° angle to the light beam. Because of Nephelometry’s sensitivity, precision and applicability over a wide particle size and turbidity range, it’s the preferred method for measuring turbidity by the EPA.

The DTS-12 is simple to configure and use, offering a standard SDI-12 output for communication with data loggers or telemetry devices.
