Description
The E+H Memosens CPF81E Digital pH Sensor is a durable, digital solution for accurate pH monitoring in harsh application environments and media, with a gel-compact electrode and double chamber reference system. An integrated assembly design reduces installation space required, and is easy to operate with Memosens 2.0 technology. The CPF81E monitors flotation, leaching, neutralization and inlet/outlet. Extended storage of calibration and process allows for more accurate trend identification and expanded predictive maintenance, with secure digital transfer of historical data. The double junction feature better protects against electrode poisoning ions such as S2- or CN-, and a robust polymer housing reduces risk of mechanical damage. These features combined with the non-contact, inductive signal transmission method of the CPF81E ensures maximum process safety.
