Description
The Signet 4150 Turbidimeter provides accurate and reliable water quality monitoring for municipal and industrial applications.
The 4150 uses the Nephelometric method to calculate the turbidity of a sample as it À ows through a viewing chamber. Models are
available that use white light technology as required by the U.S. EPA 180.1 standard, or select the models that use infrared technology
as required by ISO 7027.
Periodic calibration is mandatory with most turbidity systems, and the 4150 makes it fast and easy with sealed, reusable primary
calibration standards.
Two dry contact relays serve as high or low alarms, with programmable setpoints and time-based delays to prevent false alarms.
Additional features include a bright backlight for the display and a convenient holder for the cuvette during calibration.
An ultrasonic automatic cuvette cleaning system is standard for 0 - 100 NTU/FNU systems and optional for 0 - 1000 NTU/FNU systems.
