ultratherm heat mats, proportional heating + herpstats

just curious on the herpstat intro+:

i have ultratherm heat mats from Reptile Basics and with my Jump Start thermostats i'm having a hard time having steady regulation. i know there's a 2° delta but the actual temp isn't +-2°, almost like +-3 or +-4. it's not terrible but it is worrisome.
i bought the herpstat intro+ (not here yet) to try and rectify this so i'm looking for any insight into ultratherm mats or the herpstat intro+ on their own. i have a glass tank and a T8 so they handle heat a bit differently: on the glass tank i used to have a Zoomed adhesive UTH but i wasn't a fan. any insight into the Ultratherm or Herpstat intro+ would be much appreciated.

I have the intro+, what is your exact question?

i guess the term "proportional heating" is something i'm not familiar with. i think on their website it says something like 0.9° accuracy... i guess i'm wondering how you like yours. sorry for the ramble up there!

On/Off-----What you have will have a swing from the set temperature. If its +/-2 degrees this means it should function between 87 to 92 degrees is set for 90 degrees.

Proportional and Dimming will adjust the power output to keep the heat output at or close to your set temperature.

Pulse will either rapidly or slowly pulse the power to get your temperature to the setting.

Probe placement is the key to getting a good set-up and its different per environment as none of our houses are identical.

thank you!

does anyone make a UTH with a proportional thermostat with probe built in/all in one?

not to the best of my knowledge.

i will say: i hooked my Intro+ up to my T8 today and oh my goodness i can't believe i've survived with on/off 'stats for over 2 years. herpstats are superb! i'm so glad i spent the money.
however, maybe someone can help with setting my other one up to my glass tank. obvi the T8 has a place for the probe, but idk where to put the probe for my glass tank. yes between the UTH and glass, but i feel the space the probe leaves interferes with an accurate temp reading. the jump start 'stat was tough to dial in with the probe between the glass and mat, but still had a wider range than i was comfy with, so i had to change it. currently with my Jump Start 'stat: the probe is aluminum taped to the underside of the UTH, with the UTH flat against the glass. i've monitored it and it regulates okay (checked with temp gun), but the Intro+ instructions state to not tape the probe. any suggestions? sorry for the wall of text!

thanks to the folks here on this forum I've never paid so much attention to how a UTH works and it's pit falls. that said, even with all the useful work arounds presented on this site, I have to say that so far it seems like there is a desperate need in the industry for someone to produce a better overall solution to the issue of heat and temperature control for BP's and presumably all reptiles. the heating unit, the heat balast (the mass that is heated) and the proportional thermostat need to be all in one and moveable/removable and easily cleaned. Heat lamps are crazy wasteful and cause a major headache, they may work great for desert creatures but pose a real hassle when trying to nail particular humidity and temperature gradients. it's kind of amazing that there is not a simple solution that can be easily purchased in chain pet stores. it pains me to think what most reptiles that are sold to first time buyers are being subjected to.

Chain Box stores DONT specialize they generalize.
Its not that hard to do. The problem is that people dont research until after the fact and then over complicate it after researching.
