System Components

HydroGuard has two primary units: the analyzing unit and the control unit. The analyzing unit performs the
actual measurements. It contains the following components:
Colorimetric Reading Cell - measures free (and optionally total) chlorine levels in the water using DPD
reagents and a closed-cell, digital photometer.
Flow Cell - contains the sensors, including the pH, Redox (ORP), and temperature sensors.
Reagent Bottles – contains the reagents used by the colorimeter to measure chlorine levels in the water.
Automatic Pumps and Solenoid Valve - accurately controls the flow of water and reagents into the
colorimeter, making every measurement as accurate as possible.
The control units include all electronics and software that control the measurements performed in the
analyzing unit and the chemical dosing by external dosing systems. It includes the following components:
Control Panel - calculates the measurement results and determines the required chemical dosing to
maintain an appropriate chemical balance, and provides data to external devices such as Expert Pool remote
system.
Colorimeter Module - controls the colorimeter and associated components, such as the reagent pumps and
solenoid valve. It calculates the accurate chlorine level.
Tube Sensor Module – receives the signal from the pH, Redox, and temperature probes.
Keyboard Panel - mounted on the cover of the control module, it functions as HydroGuard's user interface.
The control panel displays current measurements and indicates alarms. All settings and adjustments are
performed through the control panel.
I/O Module (Input/Output) – Power Supply to the controller and relays. Contains the relays that control
external dosing systems.
