SKZ is honored to be a trusted partner of The Coca‑Cola Company – a Fortune 500 leader for whom water quality is foundational to every product. From the water used in syrup dilution to the final beverage and the wastewater discharged from plants, turbidity measurement is a critical parameter that affects taste, safety, and environmental compliance. That is why Coca‑Cola has integrated the SKZ TU200 turbidity meter into their quality assurance protocols across multiple facilities worldwide. This portable, high‑performance instrument delivers laboratory‑grade accuracy across a wide range of turbidity levels, backed by SKZ’s unwavering commitment to precision, durability, and responsive service. Our latest shipments reached Coca‑Cola sites in mid‑2026, and order volumes continue to rise as more plants adopt this reliable solution – ensuring that every drop meets the company’s exacting clarity standards.
The TU200 features two intelligent measuring ranges: a low range of 0‑20 NTU for high‑clarity samples such as treated water and final beverage blends, and a high range of 20‑200 NTU for influent, wastewater, or process intermediates. This dual‑range design ensures that each sample is measured at the optimum sensitivity, avoiding the compromise of a single‑range instrument. For Coca‑Cola, this means accurate readings whether testing the near‑distilled water used in mixing or the more turbid backwash water from filtration systems – all with a single, versatile meter.
The TU200 employs the infrared transmission method in full compliance with ISO 7027 – the international standard for turbidity measurement. The 860 nm infrared light source effectively eliminates colour interference, which is particularly valuable for Coca‑Cola’s applications where samples may be coloured (e.g., caramel‑coloured syrup or fruit‑flavoured beverages). Unlike visible‑light meters that overestimate turbidity in coloured solutions, the TU200 delivers stable, true‑to‑value readings regardless of sample hue – ensuring consistent quality assessment across the entire product palette.
The TU200 supports three industry‑standard turbidity units: NTU (Nephelometric Turbidity Units) for general water testing, FNU (Formazin Nephelometric Units) for ISO‑compliant measurements, and EBC (European Brewery Convention) for malt, beer, and soft drink applications. The ability to switch between units with a single button makes the TU200 adaptable to Coca‑Cola’s global operations, where different regions or internal protocols may demand specific unit conventions. This flexibility eliminates the need for separate instruments and simplifies data harmonisation across international teams.
The TU200 features adaptive resolution that automatically adjusts the displayed decimal places based on the measurement range: 0.01 NTU in the low range (0‑20), 0.1 NTU in the mid‑range, and 1 NTU in the high range (20‑200). This auto‑switching ensures that operators capture even the most subtle turbidity variations – critical when monitoring the effectiveness of membrane filtration or detecting early signs of microbial growth that can increase turbidity. For Coca‑Cola’s quality teams, this resolution adaptability means greater sensitivity without sacrificing practicality.
With an accuracy of ±2% of the reading plus 0.02 NTU, the TU200 delivers reliable data even for ultra‑low turbidity samples (e.g., 0.5 NTU). This level of precision is essential for Coca‑Cola, where the water used in final product mixing must often meet turbidity specifications below 1 NTU to ensure taste consistency and visual appeal. The TU200’s accuracy gives operators confidence that every batch is within tolerance, reducing the risk of off‑spec production.
Repeatability of ≤1.0% ensures that repeated measurements of the same sample yield virtually identical results – a key requirement for Coca‑Cola’s high‑throughput quality laboratories where multiple operators may test the same batch. This low deviation reduces measurement uncertainty, streamlines validation, and supports robust statistical process control. With the TU200, Coca‑Cola’s teams can trust that variability comes from the sample itself, not from the instrument.
The TU200 exhibits drift of less than ±1.0% of full scale per 30 minutes, meaning the zero point and sensitivity remain remarkably stable over extended measurement sessions. This stability is invaluable for Coca‑Cola’s production lines, where continuous monitoring of multiple samples during shift operations is routine. Operators can run batch after batch without frequent recalibration, improving efficiency and reducing downtime.
The TU200 supports a comprehensive 3‑point calibration using standard solutions of 2 NTU, 20 NTU, and 200 NTU. This full‑range calibration ensures that the meter performs accurately across its entire measuring spectrum – from the cleanest finished water to the most turbid process streams. Coca‑Cola’s quality managers appreciate this rigorous calibration approach because it provides traceable, defensible data for internal audits and regulatory reporting. The calibration process is straightforward, allowing site technicians to maintain the instrument with minimal training.
Coca‑Cola’s continued trust in SKZ is a testament to our unwavering dedication to quality and innovation. Our latest shipments of TU200 turbidity meters have been deployed across multiple Coca‑Cola bottling plants, and demand is steadily rising as more facilities adopt our water quality solutions. At SKZ, our promise remains unchanged: laboratory‑grade precision, robust reliability, and service that goes beyond the sale. Together with The Coca‑Cola Company, we ensure that every drop of water – whether in the bottle or returning to the environment – meets the highest clarity standards – one measurement at a time.
