Product Description:

Apera TN480 uses an infrared light source and 90° scattering method, which is compliant with the ISO 7027 method. The instrument is designed for water quality professionals, offering long-term reliability in high-accuracy turbidity measurement with an intuitive operating system, simple calibration, and GLP data management.

  • The infrared light source is especially ideal for testing solutions with color.

  • TruRead measurement mode automatically takes multiple consecutive readings, and calculate their average, minimum and maximum value, as well as displaying each set of data in a brief test report. TruRead is a much better way to determine the true turbidity of your samples, rather than relying on just one reading. It's especially suitable for sample solutions with rapid settling and continuous measurement changes.

  • 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. They must not be frozen.

  • Zero turbidity error reminder: the instrument has zero-point calibration and zero-point error reminder to ensure high accuracy for low-turbidity solutions.

  • Large TFT color screen with simple operation guide, supporting English, Spanish, and Chinese.

  • 200 sets of data storage with USB data output to PC (Windows-based), real-time clock display, calibration date check, automatic power off, and low battery reminder.

  • Everything comes in a rugged carrying case, including AMCO calibration solutions (0, 20, 100, 400, 800 NTU), 6 pieces of sample vials, USB cable, silicone oil, a microfiber wipe, PC-Link software flash drive, and user manual.
