Description

Accuracy and longevity at your fingertips.

Whether a retrofit or a new installation, EasyFerm Plus PHI pH sensors come with industry standard electrical connector options and temperature compensation. If connecting to a controller, a wide variety of adapter cables are available to mate with any device.

Only Hamilton Company has specialised membrane glass for biopharma applications. PHI glass offers high chemical robustness and very little shift aftere repeated autoclave and SIP sterilisations. The Phermlyte electrolyte paired with a pre-pressurised reference and the HP Coatramic diaphragm delivers constant electrolyte flow, resulting in drift free measurement for hte life of the sensor.

Traditional sensors offer a standard mV signal that works with existing bioreactors and transmitters. Arc sensors can be connected directly to the control system through 4-20mA or digital signals. Memosens sensors are fully compatible with all existing Memosens transmitters on the market.
