The VisiFerm DO Arc is designed to meet the demanding needs of hygienic applications in the biotechnology, bio pharmaceutical, and food and beverage industry. The VisiFerm DO Arc optical dissolved oxygen sensor offers a simple way to upgrade from traditional polarographic sensors. The sensor measurement principle offers increased accuracy and reduced maintenance while the output provides both 4 - 20mA and Modbus digital outputs.
Introducing VisiFerm RS485
Hamilton's next generation VisiFerm drastically reduces calibration frequency and has a higher robustness. Learn more about the new sensors:
Compatible with existing bioreactors
Some new bioreactors are designed to directly receive the Arc 4-20 mA and Modbus signals. For older bioreactors that require a nanoAmp (nA) sensor output the VisiFerm DO Arc is capable of simulating this signal allowing for direct replacement of polarographic sensors with optical technology.
VisiFerm Sensor Caps
The standard H0 cap is the default option for most applications. The H2 cap has a convex design to minimize bubble accumulation and a PTFE membrane that increases the chemical resistance.
Connecting a VisiFerm
The VisiFerm requires more power than a traditional polarographic sensor. Some bioreactors provide this power and others require an external power source. Hamilton offers a variety of powered cables with various connectors to accommodate most installations. If your reactor uses a nonstandard connection contact Hamilton to find out about custom cabling options.

Why should I upgrade my optical DO sensor to VisiFerm RS485?
How do I communicate with an Arc sensor?Arc sensors have a built-in micro-transmitter within the sensor. ArcAir software is a powerful tool to access data, configure and calibrate the sensor. This can be done with Bluetooth wireless communication or with a wired connection directly to a PC.
Whats the difference between a VisiFerm sensor with ECS output and a sensor with Arc?The ECS interface mimics a traditional polarographic DO sensor output signal (nA). The Arc output provides both 4 - 20mA and Modbus digital outputs.
Which wireless adapter do I need for my sensor?Hamilton makes two Bluetooth wireless adapters - Wi 1G and Wi 2G. The Wi 1G is designed for VisiFerm sensors using the ECS (nA) signal. The Wi 2G is better choice with Arc sensors.
