Traditional sensors offer a standard mV output signal and a wire variety of electrical connectors to work with most transmitters and controllers.
Arc intelligent sensor technology securely stores your sensor data and outputs your measurement information directly to the control system.
Memosens technology allows upgrading an existing installation with proven Hamilton pH sensor technology.
Phermlyte electrolyte paired with the pre-pressurized reference and HP Coatramic diaphragm delivers constant electrolyte flow resulting in drift free measurement over the life of the sensor.
Glass Membrane Options
Only Hamilton has specialized membrane glass for biopharma applications. PHI glass offers high chemical robustness and very little shift after repeated autoclave and SIP sterilizations. HB glass is a good choice for fast recovery after CIP and SIP cycles.
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.

Traditional vs. Arc vs. 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.
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 DesignPre-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 ErrorpH 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.
