A simplified two-module design includes the sensor and the controller interface. The controller accepts two turbidity sensors€”adding a second 1720E sensor makes a system with two complete turbidimeters. Connections are simple plug & play.
The 1720E Turbidimeter uses the sc200 Controller to receive data from up to two sensors. A built-in data logger collects turbidity measurement at user selectable intervals （1-15 minutes）, along with calibration and verification points, alarm history, and instrument setup changes for 6 months. Communications using MODBUS®/RS485, MODBUS®/RS232, LonWorks® protocols or the wireless IR port are available. The sc200 Controller is also compatible with AquaTrend® Networks. Local display, recall, graphing, and trending in CSV format make chart recorders redundant.
Meets and exceeds USEPA Method 180.1 for measuring turbidity for drinking water compliance. One controller accepts up to two plug and play sensors giving you two complete turbidimeters. Sensitive to fine changes in low level turbidity with a built-in bubble removal system. Built-in datalogger stores up to 6 months of data. Versatile digital output-MODBUS protocol, LonWorks or wireless IR port. Two year warranty.
The 1720E Turbidimeter reflects 45 years of Hach leadership in turbidity measurement science. Hach has the largest turbidimeter installation base in the world. And, Hach offers a two-year warranty on the 1720E.
