TempPro claims ±2% RH accuracy from 20% RH on four models, 30% on six, through 80% RH. Refresh speed differs.
For faster readings with that wider band and a backlight, TP350 and TP358 refresh every 10 seconds; TP60B and TP260B take 30 seconds.

A faster display is a different question from remote updates
TempPro display or base refresh intervals run from 10 to 50 seconds. These values describe the main unit, so they cannot tell you how frequently a remote sensor transmits. Compare the chosen package’s sensor instructions separately.
The base-unit battery descriptions also exclude any extra batteries needed by remote sensors. Decide where you will read the screen and which rooms need sensing before treating a package as complete.
Read the humidity band attached to the accuracy claim
TempPro gives a humidity accuracy of ±2% RH from 30–80%, with ±3% RH otherwise, for some models; other entries extend the ±2% RH band to 20–80%. Keep those conditions attached to the maker’s tolerance. A tolerance is not a calibration measurement we performed.
Backlight descriptions conflict for some TempPro entries, leaving those values unknown. Selecting a backlight preference excludes them. Choose screen visibility and battery arrangements separately from the stated accuracy, and do not treat a humidity readout as proof that a room is free of moisture problems.
Before you buy
Does a humidity monitor lower the humidity?
No, it only reads it. To bring humidity down or up you'd need a dehumidifier or a humidifier; these TempPro units report the level so you know when to run one.
Do all ten read the same humidity range?
Every model here reads 10 to 99% RH by TempPro's figures, so range won't separate them; where the tighter accuracy band starts does. Below each tighter band, and above 80% RH, TempPro states ±3% RH. Within the shared 30% RH-to-upper-bound band, all ten make the same claim, so batteries and backlight can decide it.
Do the battery counts cover the remote sensor?
They're for the display or base unit only. Three run on a single AAA (TP150, TP50 and TP357) and seven on two, and the indoor-outdoor models' remote sensors take their own batteries and keep their own update interval. TP60B and TP260B are indoor-outdoor base stations.
Why is the backlight blank for two models?
The TP50 and TP62B pages contradict themselves about the backlight, so both stay blank, and choosing Yes or No for backlight means neither can count as a match. Five others have a backlight and three don't.
