Turbidity meter series Turb PLUS 2000

Safe measurements by integrated bubble trap and ultrasonic cleaning
Easy calibration with standards that are traceable to Formazine
Standard-compliant measurement according to US EPA 180.1 and DIN EN ISO 7027, respectively
High accuracy, especially below 40 NTU

The nephelometric turbidity meters of series Turb PLUS 2000 can be used for nearly all applications thanks to its large measuring range. By using white or infrared light and the respective standards, the meters meet the requirements of the US EPA 180.1 as well as those of the DIN EN ISO 7027. Instrument with white as well as infrared light are equipped by default with an integrated bubble trap and ultrasonic cleaning, which saves time and effort. If needed, a set with additional external bubble trap is available.

Calibration solutions need to be ordered separately.
