Main Featured: Flow rate measurements on channels with constrictions or weirs. Preset calculation exponents or freely programmable by user. Possibility of calibration with table of up to 20 points, for nonlinear functions. Dual data logger for instantaneous measurements and totalized volumes. Graphic display with indication of real-time values and stored values in graphical or tabular mode. MODBUS RTU communication protocol.

The electronic controller displays the measured substance in mg/L and provides whether or not to activate the dosing components designed to control or correct it. The operating and maintenance costs are very low and, above all, the system calibration is performed automatically at each measuring cycle.

The analytical procedure is used for spring waters, groundwater, water from rivers and lakes and water destined for human consumption after an appropriate treatment. The method can be applied to samples with the base color similar to that of the platinum - cobalt reference solution (yellow - brown). The color of a water is generally given by organic substances, such as humic and fulvic acids (to which a yellow - brown coloring may be assigned) or by salts of some metals such as iron, copper and magnese. Observing the light transmitted through a thickness of a few meters, the color of water is of course variable in blue shades. The presence of colored foreign substances causes a variation of color in infinite shades. The apparent color, due to substances dissolved and suspended into the water, must be distinguished from the real one, only due to dissolved substances.

Compact size. No reagent (except for NaOH for Ammonia). Built-in automatic washing system. Extremely fast response time. The running costs are very low as the UV spectrophotometric measurement principle does not require the use of analysis reagents. Extremely simple hydraulic system with pipes with large diameter. The automatic cleaning system keeps the measuring cell clean for long periods with no need for intervention. The tank only needs to be filled with cleaning solution (5% sulphuric acid) once a month uilt-in peristaltic pump for sampling.

Complete and flexible system for a wide range of applications in water treatment with easy to use software and automatic recognition of sensors: available in two configurations, with up to two (2) and up to four (4) simultaneous measurements, freely selectable. Equipped with two RS485 serial ports: one (1) for sensors with RS485 digital interface and MODBUS RTU protocol and one (1) opto-isolated for the connection with the communication devices (Setup Computer, Remote Control Terminals etc.) of the local networks. Incorporates a Real Time Clock (clock with date) which allows the software to archive the data chronologically to the flash memories also used for storing LOG files of the events.

Developed by Chemitec for industrial applications, it is equipped with an output for proportional control, control functions of the probe conditions and other various outputs. The user has full control of the programming.

The 70 has been developed by Chemitec for industrial applications and is especially suited to the drinking water and swimming pool water treatment sectors. It is equipped with all the analogic and digital outputs to be able to control the pump and valve actuators also in a proportional mode (PID and PWM mode). The intuitive 70 series is equipped with a user-friendly interface and touch screen for quick and simple control. Up to eight parameters can be measured, displayed on the main screen and stored in the internal data logger, which can be consulted on the screen via graphic mode or downloaded via internal Wi-Fi mode.
