What to use to secure thermostat probe?

Hello,

I just read in my Herpstat manual:
”We do not recommend using aluminum tape to secure the probes. This can cause false readings and poor regulation.”



Welp, my probe has been secured with aluminum tape for the past couple weeks.
what do y’all recommend for securing sandwiched thermostat probes?


Thank You.

I use clear gorilla tape

I usually put tape across the cord close to the probe, and nothing on the probe itself.

I just tape the base of the probe cord to the bottom of the tub/tank about 2" away from the UTH using insulated duct tape (leaving approx. 6" of cord until the probe is where I want my UTH to rest). Then I place the UTH in position and use HVAC tape on the three sides that do not contain the wires. This seems to be a secure enough fit (almost pouch-like) that the probe is snug but still allows for a little air flow. I also am able to re-check the position of the probe when I remove/clean the hide by moving the substrate to see through the tub (though I have never had to re-adjust)!

I use aluminum tape to secure my probe because it's against the heat mat, but I tape the wire and not the probe itself. IMO it's best to not have any type of tape on the part of the probe that detects the temperature.

Another step I take for extra safety is to tape the probe to the heat mat, and then secure the heat mat to the bottom of the enclosure with the probe sandwiched in between. This ensures that if the heat mat adhesion gives away partially, the probe will be attached to the heat mat and won't overheat since it will always be in contact with the heat mat.
