About these items Calibration solutions: These are turbidity calibration solutions available in different packs. A 4 - pack with concentrations of 20 NTU, 100 NTU, 400 NTU, and 800 NTU is compatible with either TN2000 or TN1000 digital water turbidity meters, and a single 0 NTU solution for zero - point calibration. Sealed and disposable design: The solutions come in sealed bottles (non - openable) for the 4 - pack, avoiding contamination and concentration drift for single - use calibration. The disposable 100ml solution also prevents contamination from reuse. Reliable quality: Being EPA - approved, these calibration solutions ensure authoritative and traceable calibration data, which is crucial for professional water quality analysis. Convenience: The 4 - pack and 0 NTU solutions require no preparation, allowing for quick calibration in seconds. The 100ml solution offers cost - effective multiple calibrations. Sa fe and stable: The solutions have a harmless, non - corrosive formula compliant with safety and laboratory security standards. High - molecular polymer technology ensures a stable and uniform formula with no precipitation or drift. Key Differences The 4 - pack calibration solutions (TN500 - 1 for TN2000 and TN200 - 1 for TN1000) have multiple non - zero calibration values (20, 100, 400, 800 NTU) in 20ml sealed bottles for single - use calibration. In contrast, the TN500 - 2 solution is a single 0 NTU calibration solution with a 100ml volume, used for zero - point calibration and multiple calibrations due to its larger volume.
