Memosens CPS71E

E+H CPS71E Water Quality Analysis PH Electrode

Memosens 2.0 pH electrode, suitable for chemical process and toxic medium measurement

Replacing CPS71D, but now CPS71E is mainly used in the chemical industry, with all models featuring ion trap design for rapid response.

The overall price is more advantageous than the CPS11D-7BTxx series, and the sanitary model is now replaced by CPS61E.
CPS71E-AA7BTB2 replaces CPS71D-7TB21, with a range of 0-14 and 0-140 ℃, equipped with one ceramic membrane and an ion trap.
CPS71E-AA7BTC2 replaces CPS71D-7TC21, with a range of 0-14 and 0-140 ℃, equipped with 3 ceramic membranes and an ion trap.
CPS71E-AA7HTP2 replaces CPS71D-7TP21, with a range of 0-12, pressure type, 0-140 ℃, equipped with one ceramic membrane and an ion trap.
CPS71E-AA7BTU2 replaces CPS71D-7TU21, with a range of 0-14 and 0-140 ℃. It comes with one ceramic membrane and an ion trap, and can be installed upside down with E+H.

Memosens CPS71E electrode is particularly suitable for harsh operating conditions. The built-in anti pollution reference system adopts a moisture-proof and waterproof design, which can reliably measure corrosive media such as heavily polluted media, strong acids, and strong alkalis. The CPS71E electrode adopts Memosens 2.0 digital technology, which supports extended data storage, saving calibration parameters and process parameters, and is the basis for implementing pre maintenance. Allow laboratory pre calibration of sensors, rapid on-site replacement of sensors, and minimize production downtime as much as possible.

advantage
The electrode specific ion capture trap effectively prevents toxic diffusion of the lead and reference system, and can measure strong acids and bases. The electrode has a long service life.
Optional pressurized reference system for reliable measurement of easily clogged media, such as dispersions.
Allow electrode inversion and flexible installation
Inductive cable connections and non-contact signal transmission avoid the influence of humid and corrosive conditions on measurements, improving process integrity.
Quickly replace electrodes on site, shorten production downtime, and reduce operating costs.
Memosens 2.0 digital technology supports extended data storage, saving calibration parameters and process parameters, and supporting trend recognition and pre maintenance. It is also the foundation for promoting IIoT technology.
