"The TB400 is ideal for on-site Turbidity readings due to its small and compact size"

  • Description

    Extech TB400 Portable Turbidity Meter

    Turbidity refers to the cloudiness or haziness of a fluid, caused by a large number of individual particles that are invisible to the naked eye. The measurement of turbidity is a key test of water quality.

    The Extech TB400 Portable Turbidity Meter comes complete with all of the accessories in order to conveniently test the turbidity of municipal water, consumable water and other aqueous solutions where fluid clarity is important. 

    Powered by six AAA batteries, the Extech TB400 turbidity meter is portable, allowing for instant measurement and analysis on-site, rather than collecting samples to be taken back to a laboratory. It also has Data Hold and Min/Max Calculations with Record/Recall functions built in.
