EasyFerm Plus ORP Sensors
EasyFerm ORP Traditional
EasyFerm Plus ORP sensors have the all the advantages of our pre-pressurized reference design combined with a large platinum electrode surface for easy cleaning in sanitary applications.
EasyFerm ORP Arc
Arc technology with a variety of sensor length options make this versatile sensor ideal for process control and monitoring in bioprocesses.
Phermlyte Electrolyte
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.
Large Platinum Electrode
Easy to clean with lots of surface area works well in applications where coating and build-up on the sensor is a concern.
Sensor Outputs
Traditional ORP 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.

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. -
What solution should I store my pH or ORP probe in?
Hamilton recommends storing pH and ORP probes wet in either Hamilton Storage Solution (Ref 238931) or in 3M KCl solution. Click to see the pH/ ORP Sensor Storage and Regeneration Knowledgebase for more information. -
How do I clean an ORP sensor?
The platinum band around the tip of the ORP sensor can oxidize over time. Light scrubbing with a mild abrasive such as toothpaste will remove the oxidization. Rinse with potable water and store in storage solution prior to usage
