What is the primary benefit of a continuous-reading turbidimeter?

A continuous-reading turbidimeter provides real-time data on turbidity levels, enabling immediate process adjustments and consistent quality control without manual sampling.

How does the bubble removal system work and why is it important?

The system vents entrained air from the sample stream, which is crucial because air bubbles can scatter light and lead to artificially high turbidity readings, especially in low-turbidity applications.

Can this turbidimeter be integrated into existing control systems?

Units of this type, especially when paired with a compatible controller, commonly offer various output options (e.g., 4-20 mA, Modbus) for integration into plant SCADA or DCS systems.

What kind of maintenance does a Hach 1720E typically require?

Routine maintenance typically involves periodic calibration, cleaning of the sample cell, and checking for blockages in the sample lines. The frequency depends on the application and sample characteristics.

Is this unit suitable for high-solids applications?

The Hach 1720E is designed for low-range turbidity measurement. While it can handle some suspended solids, it is primarily optimised for applications requiring high clarity and precise low-level detection rather than high-solids processes.

Hache 1720E Turbidimeter

Name: Hache 1720E Turbidimeter
SKU: 3730

Price: Contact seller for price

Hache 1720E Turbidimeter, Hach 1720E Continuous-reading Nephelometric Low Range Process Turbidimeter, 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, 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.
