E+H Memosens CPS91E Digital pH Sensor

The E+H Memosens CPS91E Digital pH Sensor features a gel-compact electrode with an open aperture and double reference system ideal for accurate monitoring of fibrous media or media with high content of suspended solids. The open aperture protects the CPS91E from pressure and temperature fluctuations by preventing build up of diffusion potential at the junction. An optional ion trap greatly decreases likelihood of electrode ion poisoning, increasing service life. Extended storage of calibration and process allows for more accurate trend identification and expanded predictive maintenance, with secure digital transfer of historical data via Memosens 2.0 technology. The non-contact, inductive signal transmission method of the CPS91E ensures maximum process safety.
