Liquid analyzer pH /RedOx (ORP) /CL (ppm) eSELECT B2
--CL-(ppm)-eSELECT-B2.jpg)
eSELECT B2 is a high-precision liquid analyzer for measuring electrochemical parameters: pH, RedOx (ORP), free (total) organic or inorganic chlorine to choose from.
Liquid analyzers (controller) eSELECT B2 are equipped with a color LCD display with backlight and include a Russian menu, made in a plastic case for wall mounting.
The eSELECT B2 Liquid Analyzer contains galvanically isolated electronic components that provide a high level of immunity to electromagnetic interference.
