PH /RedOx /Chlorine controller CL eSELECT B4
The eSELECT B4 controller is a new model in the generation of high-precision liquid controllers for measuring electro-chemical parameters: pH, RedOx (ORP), free and total organic or inorganic chlorine.
The eSELECT B4 controller is available in two main modifications: for 3 or 4 measured parameters, including temperature measurement (for automatic temperature compensation of the pH level), namely:
- eSELECT B4 (3) for 3 measured parameters: pH, RedOx (ORP), CL FREE (free chlorine).
- eSELECT B4 (4) for 4 measured parameters: pH, RedOx (ORP), CL FREE (free chlorine), CL TOTAL (total chlorine).
The eSELECT B4 fluid controller is based on microelectronic technology and has the function of collecting all measurement data based on user settings. The eSELECT B4 fluid controller can be connected to the Internet for monitoring the set parameters and for storing data in the cloud storage.
Thanks to the 7 "color touch screen in the liquid analyzer, the setup and programming process becomes simpler and more understandable, and all measured values can be presented in the form of graphs on the screen.
