pH Probe

pH Probe

Buy new or used pH Probes. Find online auctions and classified ads for pH Probes on LabX.

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.
