Analog pH monitor QuadroLine® pH 296

WTW analog pH monitor QuadroLine® pH 296

The analog pH monitor for control panel installation is convincing by flexibility, reliability and a user-friendly interface

  • Low and high ohm pH input to connect also external sensors
  • Reliable measurements by automatic temperature compensation with NTC, Pt100 or Pt1000
  • User-friendly operation by different calibration procedures

The large LCD display on the QuadroLine® pH 296 as well as its clearly structured keyboard, consisting of 2 operating and 4 functional keys, make up the control panel. In addition to a dual numerical measured value display (pH/ORP and temperature), the user will also be able to see additional important operating conditions and status messages. Furthermore, the alphanumerical display is used to guide the user during the configuration and parameterization of the meter.

The 2 optional relay outputs can be configured individually as alarm, limit values or regulating contact. Depending on the selected operating mode, you can make further entries in the submenu, such as the selection of the measuring parameter, the upper/lower limit value, the regulating algorithm and the regulating range to be set. As an IF proportional regulator, the monitor can be connected directly into the process regulating circuits.
