Hache 1720E Turbidimeter

• Monitoring water quality in beverage production, including breweries and soft drink manufacturers.
• Ensuring clarity and quality control in dairy processing, such as milk and yogurt production.
• Measuring turbidity in fruit juice and other liquid food processing streams.
• Quality assurance for processed water used in various food manufacturing processes.
• Environmental monitoring of wastewater discharge from food processing facilities.

Measurement Principle

Nephelometric, typically using a 90-degree scattered light method.

Turbidity Range

Low range, commonly 0 to 100 NTU (Nephelometric Turbidity Units) or similar, for high-purity applications.

Sample Flow Rate

Typically requires a continuous sample flow, often in the range of 200-500 ml/min.

Power Supply

Commonly 100-240 VAC, 50/60 Hz, single phase.

Controller Compatibility

Designed to integrate with a dedicated controller, such as the Hach sc200, for data processing and output.

Data Logging

Units of this type typically feature integrated data logging capabilities, storing measurements and event history for several months.

Bubble Removal System

Incorporates a patented bubble removal system to minimise interference in low-level turbidity measurements.

• 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?

• Can this turbidimeter be integrated into existing control systems?

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

• Is this unit suitable for high-solids applications?

Particle counters and analysis systems are regarded as essential tools for quality assurance and contamination control across pharmaceutical, biotech and food processing sectors. When purchasing used units, buyers should verify calibration history and optical component condition, as these directly affect measurement accuracy. Industry users value their reliability and precision for meeting regulatory compliance standards. Key strengths include consistent performance across batch testing and minimal maintenance requirements when properly maintained.
