DO Sensor InPro6860i/12/120/mA/HD
Anti-Bubble Dissolved Oxygen Sensor
The InPro 6860i/12/120/mA/HD is an optical dissoved oxygen sensor with a mechanically modified hydrophilic surface. Combined with its tilted design, it prevents bubble accumulation, creating a highly stable measurement signal.
Increased Yield and Product Quality
The angled tip and hydrophilic surface prevent bubble formation. This eliminates noise for improved production efficiency and process control.
For Digital & Analog Bioreactors
This anti-bubble DO sensor has digital (MODBUS, RS-485) and analog (mA) output signals for compatibility with benchtop bioreactors and transmitters.
Sterilizable and Autoclavable
The InPro6860i/12/120/mA/HD provides fast, precise oxygen measurement, even after repeated autoclaving and sterilization cycles up to 140° C.

Stable, Reproducible Yields
Achieving consistent batches and product quality requires reliable oxygen measurement. The hydrophilic surface finish and tilted tip of the oxygen sensor prevent measurement interference from bubble accumulation that can effect yield and product quality.
Hygienic and Durable Design
Avoiding biofouling and ensure a stable signal with the PTFE coating of the OptoCap™ oxygen-sensing element. This ensures that the InPro6860i/12/120/mA/HD has the durability to withstand multiple autoclaving and standard CIP / SIP cycles.
This optical DO sensor offers the benefits and predictive diagnostics of Intelligent Sensor Management. Achieve faster start up with Plug and Measure technology. Increased system availability is provided by maintaining a stock of pre-calibrated sensors.
The 120mm InPro6860i/12/120/mA/HD reduces both handling time and running costs due to lower calibration and maintenance needs. This performance is achieved by an electrolyte-free, one-piece replacement part that is monitored by predictive diagnostics.
