Hach has a long history in leadership in turbidity measurement and has consistently provided reliable lasting laboratory turbidity meters. In the spirit of innovation and continuous improvement, Hach has discontinued its legacy 2100N, 2100AN, 2100N IS, and 2100AN IS series laboratory turbidimeters and refreshed its portfolio with two new laboratory turbidity meters.
The legacy lab turbidimeters have been replaced with the TU5200 and TL23 series turbidimeters.
The TU5200 laboratory turbidimeter employs a groundbreaking 360° x 90° Detection technology, developed specifically for the low turbidity drinking water applications. The TU5200 is also part of the TU5 Series, which combines a laboratory and online turbidimeters with identical technology that delivers matching turbidity results from both the online and laboratory readings. For more information on TU5200, please go to hach.com/p-tu5200-benchtoplaser-turbidimeter/LPV442.99.01012
The TL23 Series laboratory turbidimeters employ the same trusted optic block as the legacy 2100N/AN making it an ideal replacement for industrial and other high turbidity applications. The TL23 also has an updated and intuitive user interface similar to that of the rest of Hach’s laboratory instruments.
