Turbidity Analyzer and Control System

The EMEC Turbidity Analyzer and Control System, offers ease of use, accuracy and reliability for the monitoring and control of Water Turbidity. Using the EMEC LDSTORB2 PLUS Turbidity analyzer and controller, with the ETORB2 Series of sensors, NTU ranges from 0-40, and up to 4000 NTU are accurately measured. These systems are cost effective, and ease to operate, with NTU readings being continuous and updated every second. Built-in temperature compensation with a spray wash lens cleaner are standard.

The system below consists of the controller, and sensor and mounting options:
