pH Probe

The new R1000-4 pH Probe from Ocean Optics is designed to work with non-intrusive reflective pH patches (PH-BCG-REFLECT) but can also be used with our RedEye oxygen sensor patches. 
 
This probe consists of four 100 um plastic fibers arranged in a 3-around-1 configuration. 
 
The three illumination fibers are angled at 25.5° to focus light to the center of the sensor patch. 
 
The R1000-4's design greatly increases back reflection -- improving the signal-to-noise ratio. This is critical for ambient light and color immunity that makes our sensors so unique and efficient.
