Wincom Company manufactures a reliable, industry-standard lineup of turbidimeters widely used for water testing, environmental monitoring, and food safety testing. They offer both compact portable models and high-precision benchtop units.

Their core catalog relies on the standard 90° scattered light principle (Nephelometry), satisfying ISO 7027 requirements.

1. Top Benchtop Choice: Wincom TBD-T200

This is their premium standard benchtop unit, highly favored for complex water analysis because it combines turbidity reading with a Total Suspended Solids (TSS) measurement mode.

• Measurement Method: ISO 7027 nephelometric method (90°)

• Turbidity Range: 0 to 2000 NTU/FNU, 0 to 500 EBC, 0 to 9999 ASBC

• Resolution: 0.01 (0 to 100 NTU), 0.1 (100 to 999 NTU), 1 (999 to 2000 NTU)

• Accuracy: $\pm 2\%$ (0 to 500 NTU), $\pm 3\%$ (501 to 2000 NTU)

• Key Feature: TSS calculation depends on a customizable conversion factor, making it highly versatile for sewage or industrial run-off profiling.

2. Utility Series: SGZ & TBD Economic Series

If you need straightforward, cost-effective models for quick laboratory or field measurements, Wincom splits their classic lineup into portable and table/benchtop variants across multiple range capacities:

Common Configurations

Note on Naming Conventions: Models ending in “B” typically represent the ergonomic, lightweight Portable configurations (fitted with battery/adapter options), while models ending in “A” designate the dedicated static Table/Benchtop versions.

Key Operational Capabilities

• Stability: Across all standard series, indication stability holds steady at $\pm 1.5\%$ (F.S 30min) with a repeatability profile of le 2

• Optical Calibration: Units utilize standard Formazin turbidity solutions for routine multipoint calibration, ensuring stable baseline tracking.

• Build Quality: Usually housed in rugged, chemical-resistant casings tailored for demanding lab spaces or field environments, shipping with standard hard-carton or optional wooden casing protection.
