LIGHT-COLOUR REGULATION: hth Professional
CUTTING-EDGE TECHNOLOGY
-
hth Professional uses colorimetric-type technology (DPD chemical reagents), the safest and most effective way of checking the water's free chlorine and total chlorine content. This system is recommended and used by France's Health and Social Services Departments.
-
ASC (advanced self-cleaning) combined with an ARM (active reagent mixer) systematically guarantees a clean sample, ensuring that measurements remain accurate and reliable.
-
hth Professional is a regulation system that is constantly evolving. It is capable of analysing the most advanced parameters (turbidity, TDS, etc.) as well as the common but essential parameters (free chlorine, total chlorine, pH, temperature, flow rate). It adopts the latest advances in technology (data record and traceability on SD card, output 0-4/20 mA, etc.) and also comes with a USB RS232/RS485 module (optional).
IMPROVE SAFETY
-
Front face read out for direct reading.
-
Two clear intuitive menus in French or another language (drop-down menu) have been developed for ease of handling and use.
-
Each menu is protected by an individual password.
-
The main parameters (chlorine, pH and redox) are monitored closely: a low-level alert, high-level alert and dosage duration control alert immediately shut down the injectors.
-
If the photometer is turned off (cell cleaning, reagent supply interrupted, etc.) the hth Professional can switch to Redox mode.
IMPROVED ACCURACY AND RELIABILITY
-
hth Professional's advanced electronic technology ensures accurate monitoring of chlorine, pH and redox.
-
Thanks to photo-colorimetric technology, systematic recalibration of regulation becomes a thing of the past (1 or 2 calibrations a year are sufficient).
AMPEROMETRIC REGULATION: hth CYCL'EAU
Regulating
-
hth Cycl'eau is a quality regulator that analyzes and regulates swimming pool water chlorine content and pH.
-
For chlorine analysis, hth Cycl'eau uses a membrane probe capable of analyzing stabilized and unstabilized chlorine.
-
For chlorine and pH regulation, hth Cycl'eau uses proportional-type regulation. This process allows smoother regulation either side of the chlorine and pH thresholds.
Analysing
-
The water from the pool passes into the filter and then enters the analysis chamber containing the flow-rate detector, pH electrode, chlorine probe and temperature electrode.
-
The pH electrode, chlorine probe and temperature electrode transmit a value which is displayed on the main screen.
Informing
-
To inform the user quickly about the injection sequences or other regulation operating states, 4 indicator lights are located on the left-hand side of the unit.
-
For adjusting and viewing the settings there is an intuitive 7-key keyboard on the right-hand side of the unit.
