How trustworthy are the thermostat temps?

[bamf64]

I have a johnsons controls thermostat hooked up to both my snake tubs. I have it set for 93*. I have the probe taped to the flexwatt outside the tub. I have been measuring temps all day and I keep getting crazy readings. I have used my thermometer with a probe inside the tub and it reads 85*. I use my temp gun (I am thinking its not very reliable :/) and it says 100* and the thermostat says 93*.

WHAT IS RIGHT??

yea with my thermostat its at like 104* and the thermometer in her hide says 91. i guess there not that accurate.

My Ranco probe taped with aluminum tape to the flexwatt Reads 98-102 (I switch it around because the A/C runs colder at nite)

The accurite probe reads 91-94 under the warm hide. The thing is though, without the hide the probe will reach 88 at the most.

I though I was the only one with this problem because I am new at this. Hell I just assembled my Ranco about a week ago lol.

Oh and yeah I dont own a temp gun yet, I am gonna try to buy one this weekend.
