EasyFerm Bio MS2 Details

EasyFerm Bio MS2 pH sensors with Memosens provide digital sensor technology combined with Hamilton pre-pressurized reference technology. The sensor design is targeted at applications in food, brewing, beverage, and other sanitary applications that require biocompatibility and certification. The HB membrane glass is preferred for frequent CIP applications and quick recovery after cleaning.

These sensors are fully compatible with all Memosens input transmitters on the market. Alternately, the Hamilton H220X transmitter provides a Memosens digital sensor input with local display and hazardous area approval.

Glass Type Options

PHI
Best lifespan in frequent SIP and autoclavation applications with very low drift. The PHI glass is our recommended membrane glass for bioreactor installations found in R&D, upstream, and downstream pharmaceutical applications.

HB 
Best lifespan in frequent CIP and autoclavation applications. Fastest response time. The HB Glass is our recommended membrane glass for food, beverage, and brewing applications.

Common applications Pharma & Biopharma, Agri-Food and Beverage, Bioprocess Downstream, Bioprocess Upstream, Water, Energy, & Environment

FAQ

What is the difference between traditional, Arc and Memosens sensors?

Traditional sensors provide standard mV output and rely on a separate transmitter or controller to amplify the signal and convert to an actual reading. Arc sensors provide a built-in microtransmitter that can output either 4 - 20mA or Modbus RTU digital communication. Finally Memosens sensors offer a digital signal that works with all Memosens transmitters and analyzers currently on the market.

FAQ

What is the expected lifetime of my pH sensor?

Expected pH sensor lifetime is dependent on the application. Exposure to strong chemicals, elevated temperature, fluctuating pressure, and solid build-up can all impact the sensor life. As the sensor ages, a sluggish response may become more apparent, and will require more frequent calibrations to compensate for this change. The overall health of the Arc pH sensors can be seen using the quality indicator in ArcAir software.

FAQ

What is a pre-pressurized sensor and why would I choose it?

The electrolyte within the sensor is pressurized at the factory. This feature helps prevent against clogging and poisoning of the sensor due to the process liquid. The design is hygienic and well suited for fermentation applications found in biopharma, food, and beverage markets.
