Accuracy

Continuously flowing sample flows through the patented* bubble removal system, which vents entrained air from the sample stream and eliminates the most significant interference in low level turbidity measurement. The 1720E Turbidimeter is not affected by variations in flow and pressure.

Simplicity

A simplified two-module design includes the sensor and the controller interface. The controller accepts two turbidity sensors and adding a second 1720E sensor makes a system with two complete turbidimeters. Connections are simple plug & play.

Data Collection and Display

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, HART, or Profibus DP.

USEPA Reporting

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.

Experience

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.
