Sensor for turbidity and solids content
Turbimax CUS51D is a sensor for all wastewater treatment applications.
• Turbidity measurement in the outlet
• Solids content in sludge activation and recirculation
• Solids content in sludge treatment
• Filterable matter in outlet of WWTPs
Your benefits
• All sensor principles (90°, 135° and 4-beam pulsed light) are contained in the sensor head and enable optimum adaptation to the measuring task.
• The sensor is calibrated in the factory (on the basis of formazine). All selectable applications (e.g. activated sludge) are pre-calibrated, thereby enabling quick and easy commissioning.
• Standardized communication (Memosens technology) enables "plug and play".
• Intelligent sensor - all characteristics and calibration values are stored in the sensor.
• Customer calibrations with 1 to 5 points (max.) - can be performed in the lab or at place of installation.
