Just the tip. If the end of the probe with the wire coming out gets wet, liquid will leach into the probe and ruin it, at least that’s what happened to mine.
Also the cheap paper Atlas Scientific sticker at the top of the probe will come off in your solution possibly contaminating it.
I have had nothing but problems with this probe. It provides Inaccurate readings. The pH probe cannot be submersed, only the tip can, otherwise you will ruin the probe. We purchased this in order to speedup development time, not donate beta testing time to Atlas Scientific. It nearly cost me a client. If you read through their documentation you will find glaring errors that indicate issues with their document review process.
We also had several of their temperature probes (ENV-TMP-D) shipped to us that read almost 3deg C high at room temperatures (factory calibration). When I called them on this, they confirmed they “had a bad batch” but didn’t offer to replace my bad sensors.
Save your money and time and look into another solution.
