Hydraulic panels was designed for preliminary preparation of the analyzed liquid: filtering and setting of a rated value and stabilization of the flow in the measuring cell, in which a combination pH or ORP-electrode and temperature sensor are located, measurements antijamming security provision, as well as the pH-meter adjustment according to buffer solutions.

   Hydraulic panel is mounted near the controlled facility or in the places of the analyzed liquid supply from the controlled facility.

   The pH-meter shall be installed on the hydraulicpanel. HP-4122 can be equipped with an electronic liquid flow meter (option).

   Hydropanel HP-4122 has three versions:

• without calibration;
• with manual calibration without unmounting;
• with automatic calibration without unmounting.
