Atlas Scientific Dissolved Oxygen Probes come with a replaceable HDPE sensing membrane and a refillable electrolyte chamber, located inside the probe. Although it is not necessary to replace the sensing membrane or electrolyte solution during normal operation; the membrane can be damaged if it is hit with fast moving debris in the water.

If your Dissolved Oxygen Probe has not been in use for more than one year, the HDPE sensing membrane can dry out and the internal electrolyte solution could leach out of the probe. This kit will get your Dissolved Oxygen Probe back in working order quickly.
