APERA TN 500

APERA INSTRUMENT


DESCRIPTION :


Apera TN500 uses a tungsten filament lamp as the light source and 90° scattering method, which is compliant with the U.S EPA 180.1 method for the determination of turbidity in drinking, ground, surface, and saline waters, domestic and industrial wastes. The instrument is designed for water quality professionals, offering long-term reliability in high-accuracy turbidity measurement with an intuitive operation system, simple calibration, and GLP data management.

The meter is equipped with a large TFT color screen with plain language and graphic navigation, supporting English, Spanish, and Chinese. Intelligent functions such as automatic calibration, real-time clock display, calibration date check, auto. power off, and low battery reminder are built-in to ensure ease of use.

200 sets of data storage with USB data output to PC (Windows-based only)

The kit comes with AMCO® high-molecular polymer turbidity standard solutions (0, 20, 100, 400, 800 NTU), which are EPA approved primary standards that are safe, non-toxic and disposable, and have a guaranteed one-year shelf life. It is NIST traceable to particle size/distribution and optical density, and its inherent stability means it does not settle from suspension. Store the standards at room temperature.
