EasyFerm Bio pH Sensors
EasyFerm Bio pH - Traditional
Traditional sensors offer a standard mV output signal and a wire variety of electrical connectors to work with most transmitters and controllers.
EasyFerm Bio pH - Arc
Arc intelligent sensor technology securely stores your sensor data and outputs your measurement information directly to the control system.
EasyFerm Bio pH - Memosens
Memosens technology allow upgrading an existing installation with proven Hamilton pH sensor technology.
Foodlyte Electrolyte
This specialized electrolyte has been certified for full bio-compatibility making it ideal for use in the food and beverage industry as well as other bioprocesses where risk of cytotoxicity is a concern.
Glass Membrane Options
HB glass is a good choice for fast recovery after CIP and SIP cycles found in food and beverage applications. PHI glass offers high chemical robustness and very little shift after repeated autoclave and SIP sterilizations.
Specific Applications
-
App Note - Arc sensors in oncologic and biosimilar applications

Choosing between EasyFerm Plus and EasyFerm Bio products?
EasyFerm Plus sensors are designed to withstand repeated SIP and autoclavation sterilization cycles found in the biopharmaceutical industry. EasyFerm Bio sensors have a unique biocompatible electrolyte for applications in the food and beverage industry where CIP cleaning is commonplace. -
What is the Everef F Reference System?
The Everef-F reference system uses a silver ion barrier to separate the reference element from the electrolyte. This design prevent Ag+ precipitation from occurring and clogging the diaphragm. It is a perfect design for applications with proteins or sulfides in the process liquid. -
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. Click to learn more about sensor lifespan and expiration in the Knowledgebase article.

pH and ORP Sensor Reference Design
Pre-Pressurized vs. refillable vs. polymer vs. viscous electrolyte? This article discusses basic pH reference design benefits for each product family. -
What is a Liquid Earth (LEVP) for a pH sensor?
Some Hamilton process pH sensors have the option for a liquid earth (LEVP) connection; however many end-users are unfamiliar with its benefits. -
Sources of pH Measurement Error
pH Sensors are electrochemical devices with limited lifespans. Changing process conditions directly impact each component within the combination electrode thus can be sources of error leading to inaccuracy and eventual death of the sensor.
