Easy and Fast Operation
With the fast OptoCap replacement and the Plug & Measure ability, the InPro6970i optical oxygen sensor can be calibrated away from the process, and then quickly swapped into the process environment without the need to recalibrate. No polarization is requi
High Process Safety
The materials of construction of the InPro6970i trace DO sensor are FDA compliant and the easy-to-clean high-polished surface (N5 grade) also satisfies increasing regulatory requirements.
Enhanced Process Control
The sensor's measurement performance helps to reduce out of spec production. ISM helps to make optical oxygen measurement simple and more reliable and significantly reduces the risk of sensor failure during production.
ISM Redefines Maintenance
The built-in digital ISM technology provides the user important information about the sensor wear. Maintenance planning becomes easy, as accurate diagnostics predict when sensor maintenance will be required.
