The two-channel instrument is designed to measure the turbidity of water and
aqueous solutions. The method of measurement is nephelometric.
The dual channel analyzer is a measurement tool
consisting of one or two optical sensors and the measuring instrument (MI) panel or wall mounting.
The analyzer provides a digital and graphical indication of
measured parameters, with alarms when the measured parameter outside specified values, and to
converting the measured value into a unified output DC signal and communication with the computer
via digital interface RS-485 (Modbus Modbus RTU communication protocol), and archiving measured values.
The device has channels for measuring the temperature of the sensor and the flow rate of the analyzed liquid.
Optical turbidity sensors TU 8355, TU 8555, TU 8325, TU 8355 are connecting to the controller
Immersible sensors TU8355, TU8325 have a nozzle cup for cleaning optical lenses with compressed air.
Flow sensors TU 8555, TU 8525 are installed in the measuring cell TU 910 or in the tee.
The analyzer has a user-friendly menu and is equipped with an archive with a 1-year archiving time.
The measuring instrument of the analyzer is made of high-impact polystyrene in the housing and is placed on
the hydropanel HP-TU.01 of stainless steel.
Scope of application: water treatment, water cleaning, food, brewering, pulp and paper industry.
