The Pinnacle oxygen sensor is a 180 micron diameter disk electrode.  Standard sensors are manufactured with an integrated Ag/AgCl reference electrode.  Pinnacle's 7001 sensor series offers an option for applications where a guide cannula is unnecessary.

Note: Please allow 7 business days between ordering and shipment of sensors. The 21-day warranty only applies to glucose, glutamate, lactate sensors and carbon fiber electrodes. The sensor is warranted for 21 days, or until initial precalibration, whichever is first. Longer lead times may also apply for custom sensor types. We will only ship sensors via FedEx 2-Day or Overnight.
