The OxyLite™ Pro takes our third-generation optical/fluorescence oxygen technology and packages it into a flexible form factor featuring a touch-screen display and either 2 or 4 channels. The range topping OxyLite Pro XL can simultaneously drive up to 4 oxygen or combined oxygen/temperature sensors for the simultaneous monitoring of oxygen from multiple tissue sites (e.g. comparison of pathological versus control tissue sites), or multiple in vitro samples.
