Description
The low range turbidimeter
Compliant with EPA Method 180.1, the 1720E Low Range Turbidimeter is a trusted, continuous-reading nephelometric turbidimeter designed for low-range turbidity monitoring. A built-in bubble removal system allows the 1720E to be sensitive to fine changes in low level turbidity. When connected to a Hach SC controller, the instrument can store up to 6 months of measurement logs, verification data, and other instrument information for complete data reporting. Verification is made easy with the optional ICE-PIC module that allows for verification of the turbidimeter in less than one minute.
The 1720E is passing the torch to the TU5300 sc. The last day to order the 1720E is July 27, 2018. See the recommended products section of this page or visit HachTU5.com to learn more.
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.
Fast Calibration and Verification
Calibration and verification can be performed without loss of sample flow using the ICE-PIC™ Calibration/Verification Module. One-point calibration with prepared Stablcal™ Stabilized Formazin Solution eliminates the errors of user-prepared formazin suspension dilution. Features of the ICE-PIC Module include:
• Less than one minute to calibrate or verify the performance of each sensor
• Factory calibrated and provided with a certificate of accuracy
• Cost effective, one-time investment. No consumables are needed
• Small, lightweight design can be used for spot verification in the facility
• Available in 20 and 1.0 NTU
