Are my fish swimming in ammonia? How basic are the ashes from the recent wildfire making the stream that I’m interested in? Is my bog full of carnivorous plants ok?* All of these questions can be answered by measuring pH, a measure of how acidic or basic an aqueous solution is. You can use this to track pH in your environment wherever there’s a liquid to immerse the pH probe in.

The pH module board connects with a pH probe by way of a SMC connector. This pH probe is rated for full immersion up to the end of the cable, and can operate over a broad range of temperatures. pH calibration standard solutions not included.


  • pH

*Bogs are healthiest when they’re relatively acidic, which allows many carnivorous plants, like Venus Fly Traps, Honeydews, and others to live there.
