PH Sensor

These Sensors are great for  laboratory  testing or long term field use. Their Rugged Epoxy design makes them virtually unbreakable. This Sensor comes with a soaker bottle so the bulb does not dry out. The wire length is 30" (76cm) and has a BNC connector. 

This pH Sensor can be fully submerged indefinitely.
