Description

When non-toxicity is mandatory.

Whether a retrofit or a new installation, EasyFerm Bio HB 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.

EasyFerm Bio HB pH sensors provide a reliable solution for installations into food processing, dairy, brewing, beverage, and other processes where biocompatibility and sanitary certification are required. The pre-pressurized reference design ensures accurate pH measurement while options such as the HB glass membrane provide minimal drift when frequent CIP cycles are encountered.

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.
