Thlevel2-Pack Mini Digital Thermometer Hygrometer Indoor Room LCD Reptile Monitor Humidity Meter Gauge for Humidifiers Dehumidifiers Greenhouse Basement Babyroom

I've been using the Thlevel 2-Pack Mini Digital Thermometer Hygrometer in my AMS system, and it’s been a solid, no-fuss solution for monitoring temperature and humidity. The LCD display is clear and easy to read, even at a quick glance, and the compact size makes it easy to fit into tight spaces without getting in the way.I appreciate how responsive and accurate the readings are—there’s little to no lag when conditions change, which is crucial for my setup. The battery life is impressive, and since it comes in a two-pack, I have an extra for another part of the system or as a backup.The only minor downside is that the display isn’t backlit, so it can be a little tricky to read in dim lighting. But for the price, it’s a reliable and affordable way to keep track of environmental conditions, making it perfect for my AMS system and similar applications. Definitely worth it!

Works great accurate n easy to read display

They’re off by a few degrees but, for the price, I can’t complain so I’m not docking stars. I mostly use them to ensure winter drafts from my old windows aren’t affecting a collection of tropical house plants as well as keeping an eye on ambient humidity and they work well enough for that.

Fair quality, work fine

This is a super-cheap item; not particularly accurate*, and doesn't stand or attach securely without more effort than it is worth.*I put the 2 items that came together within 6 inches of each other, on a shelf in a draft-free space, and observed that the readings varied between them by .4 degrees Farenheit...I guess you get what you pay for!

It should be simple enough to just display temperature and humidity, but in my case I’m using it inside a 3d printer to next to filament and diseccant boxes. So either it’s too dry, below the 20% limit, or the device just broke because only displays LL for the humidity. Overall it works as intended and I’m glad I got two because the other one displays humidity correctly.

I love using these for my Leopard geckos tank and for my jumping spiders tank. Shows the temperature as well as the humidity level.

Old ones batteries died. Was cheaper to order new ones than to replace batteries. Will be ordering again in abt 2 yrs.
