Drip-free and makes probe maint. easy

I wrapped electrical tape around my BRS research grade probe to ensure a snug and water-tight fit. I used to use a bored out PVC threaded plug which required me to caulk the probe in place. This Avast fiiting makes it easy to remove the probe from my CO2 reactor for cleaning and recalibration.

Awesome probe holder

Love this probe older used two to while making an inline co2 reactor for my planted tank. One was for my temperature probe and the other was for the pH probe. It was also the most affordable I could find!

Probe Holder

Purchased this probe holder to use on an older model GEO Calcium Reactor that did not have a PH port. I drilled a hole in the lid then used some of the left over acrylic glue from the MR10 reactor kit that I purchased previously. Absolutely no leaks and fits my Neptune Systems Lab Grade PH probe perfectly.
