The Apera Instruments TN400 Portable Turbidity Meter ensures you an accurate, quick, and reliable turbidity test. It is equipped with a large clear TFT color screen (blue for measurement, green for calibration), supporting display of intuitive graphic/text operation guides and a progress bar showing measurement progress. Provided with 4 kinds of Reagecon high-molecular polymer turbidity standard solutions (0.02 NTU, 20.0 NTU, 100 NTU, 800 NTU), which are U.S. EPA certified, non-toxic, accurate, and easy to use, having evident advantages compared with traditional Formazin standard solution (highly toxic and inaccurate). The meter is CE certified and comes with a 2-year warranty (6 months for the electrode). The company designs and manufactures scientific analytical instruments like meters and sensors for pH, conductivity, turbidity, and dissolved oxygen for over 25 years, and meets ISO 9001:2008 Standards.

Nephelometric or transmittance measuring-the nephelometric measurement at 90° scattered light is advantageous for lower turbidity, whereas the transmission measurement at 180° is beneficial for medium to high turbidity values: With increasing turbidity, restray and scattering effects between particles are growing bigger. The reduction of light intensity in this case leads to a more accurate result than a 90° nephelometric measurement. Therefore, lab meters for high values are equipped with several measuring options: ratio modes calculate the final result from different measured angles. For ratiometric measurements, there is no specific standard method to be followed; rather, procedures are established by the application or industry. White light has a higher sensitivity for small particles, however, the inherent coloration of the solution has a stronger disturbing effect in this case. The IR measurement is required by DIN ISO, the white light measuring by US EPA.
