Temp Readings

[hun73r]

I have three thermometers in my large enclosure measuring the basking spot and I get three different readings.

Does anyone have any knowledge of the difference in actual temperature to the digital readout on the Exo Terra combination temp/humidity? It has a remote probe that is placed in the enclosure but it reads 6 degrees higher than the other two in the exact same spot. Two probes read within degree of each other at around 86 and the other reads 91.5 degrees. When the basking light is off they all read about the same (within a degree and a half).

I think it is because two of the probes are white and the Exo Terra probe is black, but I want to use it due to the ability to read humidity as well.

Should I just use one white and one black or just do the math and know the actual temp is about 5 degrees cooler than on the readout?

Depends on the species. I would err on the side of cooler rather than warmer. You're probably correct about the color of the probes though, color makes a big difference in heat attracted...just ask your chameleon.

I was wondering if that was the case. I'm also using the exo terro temp/humid. The basking spot reads 90 but yet apolo sits on basking all blacked out trying to absorb heat like he's too cold.

Sorry to thread jack but you think I should set temp reading around 95 to compensate?

I have decieded to use the zootherm (white probe) as the basking spot thermometer and the black probe as an ambient/humidity gauge. I am also ordering an infrared temp gun in the very near future.

again with the different temp readings

there was a recent thread that was almost identical to this one, so rather than repost everything, here it is https://www.chameleonforums.com/different-temperature-readings-39330/bear in mind that tempguns do not read air temp
