Eliminating the need for multiple sensors to accommodate large variation in turbidity, Tu•Xchange™ automatically adjusts to the appropriate range while in operation. As a result, high accuracy is achieved over the entire 0-3000 NTU range. For long-term deployments in sediment rich areas, a wiper option is now available. Tu•Xchange™ has proven to perform well long term when protected from marine growth by UV biofouling control.
Tu•Xchange™ accuracy is quoted as a percentage of reading. A sensor measuring 900 NTU is accurate to +/-18 NTU, while measuring 500 NTU it is accurate to +/- 10 NTU, based on its +/- 2% specification. As the measurement nears 0 NTU the accuracy specification also includes a floor. For example, the same sensor measuring at or below 1 NTU would have an error of +/- 0.2 NTU.
