Use this single-channel oxygen meter with standard fiber optic microsensors for 0-100% O2 range and trace sensors for 0-10 % O2 range, e.g., for invasive physiology, micro profiling etc. The device is powered via USB and has a temperature channel for real-time compensation of oxygen values if connecting an optional Pt100 temperature sensor. Windows software is included, and several devices can be controlled simultaneously from a single PC.
