Description
This paramagnetic oxygen sensor module is designed for incorporation in your analyzer systems or for the solution of oxygen measuring problems using a microprocessor or a PLC-based system.
The sensor module is maintenance-free, have a long lifetime, give a rapid and accurate signal response and is virtually insensitive to other gases. It has a compact design which meets high quality standards and easy implementation.
