## Description

HTC Instrument 103-CTH Digital Indoor Hygrometer Thermometer with Clock by Supreme Traders Supertronics1989 : desertcart.in: Garden & Outdoors

Review: No words to describe the desertcart online shopping app - Nice product as usual I have never find ever any mis product from desertcart desertcart is is best shopping app as always
Review: Useful for Baby's room - The display is good and easy to read from a distance. It shows temperature, humidity and time. The accuracy of temperature is ok but not very good. The temperature shown is about 1.5 C lower than the actual temperature (as measured by a mercury room thermometer and digitally by mi air purifier). Since the error is not random, once you know the difference you can always add eg. add 1.5 C to the displayed temperature in my case and the reading will be ok. For humidity the reading is within 5% of the humidity reading given by mi air purifier. (Mi air purifier has a built in temperature and humidity display).

### ⭐⭐⭐ Accurate temperature monitor, but why in F?
*by R***L on 16 January 2026*

Why, temperature is always sjown in F? It was too cumbersome to adjust it to C! It's made in China, but only for the US?, as only the selfish & self-centered Americans use F, lb & mile system as measurement! C should be It's default, if lousy Americans want the F, they jolly well could adjust it!!!
