WTW Turb® 750 IR fulfills the demands of many lab and industrial applications for a AQA supported turbidity measurement up to 1100 FNU/NTU. With the Intelligent Reproducibility and Plausibility-Check (IRPC) reliable findings are proven.

Measurement conforming to standards in drinking water, lab and industrial applications.

WTW Turb® 750 IR measures nephelometrically according to DIN EN ISO 7027-1 up to 1100 NTU/FNU with AQA support and PC documentation:

• Well proven WTW® optics with fast data output
• Multiple measurement and data evaluation with Intelligent Reproducibility and Plausibility Check (IRPC)
• Bench-saving despite comprehensive functionality
• Invincible price-/performance ratio

Turbidity stands for an indicator parameter on quality in drinking water, waste water process and many industrial applications. The measurement is support by:

• Measurement procedure fulfilling DIN EN ISO 7027-1 *)
• Function keys
• Comfortable menu-guided 3-point standard calibration
• Flexible calibration with 2-5 user-defined calibration points
• QuickCAL: 1-point-calibration at 10 NTU
• AQA, calibration interval and records with PC-documentation

*) For drinking water measurement acc. to  US EPA 180.1 Turb® 750 T is the appropriate instrument.
