Portable Turbidity Meter, ISO 7027 Water Testing with 2000 NTU Auto Range

Description

LAQUA TB220 Portable Turbidity Meter is designed for routine water quality testing where reliable turbidity measurement and easy field handling are important. This waterproof portable meter uses ratiometric turbidity measurement with nephelometric light scatter and transmitted light signals, helping support dependable readings across a broad turbidity range. Its large backlit LCD, simple user interface, and smiley reading stability indicator make day-to-day operation more convenient, while the shock-resistant, scratch-resistant, and non-slip housing supports practical use in laboratory and field environments.

The meter offers a turbidity range of 0.00 to 2000 NTU and supports up to 4 selectable calibration points using Styrene Divinylbenzene, SDVB, polymer standards at 0.02, 20, 100, and 800 NTU. It is compliant with ISO 7027 and DIN EN 27027, making it suitable for professional water quality workflows. Built-in memory stores up to 2000 data with real-time clock and date and time stamp for better record management, while PC and printer compatibility support data collection and printout. The TB220-K kit is supplied in a durable carrying case complete with 0.02, 20, 100, and 800 NTU standards, 4 sample vials, silicone oil, cloth, instruction manual, and quick manual for ready-to-use routine turbidity testing.
