Those digital thermometers are they a stick on or a actual digital w/ a probe-? I just saw a digital in a tank that was just that no probe-

If there is no remote (on a long wire) probe , I'd replace it with digital probe that has a remote probe , this will give you more options
ie
> dangle the probe in the air , will measure radiant heat from basking globe or CHE + air temperature ( natural convective heat transfer (in a proper enclosed tank (solid lid) or if the top is "open" warmed air before it escapes to warm up the boundary layer of air just below the room's ceiling
> place the probe so it near the warm zone wall or cool zone wall but not in contact with the wall surface , this will give an indication of a combination of circulating air temperature + radiant heat
> place the probe so it's directly under the basking globe but not in physical contact with the basking spot's surface , will give an indication of the direct radiant heat and the temperature of turbulent airflow rising from the warmed basking spot's surface + reflected radiant heat from the basking spot
> place the probe so it is in direct physical contact with the basking spot's surface and directly under the basking globe , will indicate the combined temperature from the warmed basking spot ( by conduction of heat from the surface to the probe ) + radiant heat from the basking spot , conductive heat transfer to the probe in this instance will be minimal ( inside the laminar convective boundary layer ).
> place the probe so it's under the basking spot but not in physical contact with the structure of the basking spot , this will give an indication of air temperature ( by convective heat transfer to the probe ) in the basking spot and will shield the probe from radiant heat transfer.
> place the probe under hide (not in physical contact with the hide or the substrate) , will indicate the air temperature under the hide by convective heat transfer to the probe.
> place the probe in the substrate (if you have non-solid substrate) , will give the substrate temperature by heat conduction to the probe.
Much more versatile than a digital thermometer with a builtin temperature sensor and more accurate and meaningful and useful temperatures are attainable.
Humidity : if it's under 70 % it's fine. Short excursions in RH to 80% or there abouts are also acceptable .
