Mini Hygrometer Thermometer 2PCS Mini Digital Humidity Gauge, AikTryee Hygrometer Indoor Humidity Monitor, Temperature Humidity Gauge Meter for Humidors, Greenhouse, Garden, Cellar, Closet, Etc

Got these for my incubators. They seem pretty accurate. Theyre small, but easy to read.

Purchased a set of two, used a Boveda One-step calibration kit over 24 hours to establish a baseline for both hygrometer readings: (1) Temp read 4 degrees low (displayed 69* to actual 73*); humidity read 3% high (displayed 78% to actual 75%) (2) Temp read 3 degrees low (displayed 70* to actual 73*); humidity read 4% high (displayed 79% to actual 75%) According to the product documentation Temperature measurement accuracy: ±2℉; Humidity measurement accuracy: ±5%RH. These systems were out of spec for temp and within spec for humidity. Im using these in clear plastic containers to store cigars while I reseason my humidors. As a rough guide they work fine, the display is clear and easily readable through the container wall. DONT rely on these as precision instruments though, pickup a more precise hygrometer for a long-term solution. (Xikar makes a nice one that can be calibrated)

These read differently from each other when side by side. Do not rely on readings!

Even came with batteries! And more batteries for later. Very nice units.

I bought the two pack and they are cheap hygrometers but good value. They are not 100% accurate as both are in same humidor and have different readings. About a 2-4% difference.

Both worked fine and accurate

I bought this so time ago and it still works! I can read it perfectly and i believe it gives me a better accuracy than other that i have bought! Will update if anything changes.

Ok - I received the 4 pieces I ordered. Fast. See my photos - pretty damn accurate. SO NOW - I see two batteries included for EACH UNIT, even though they have good batteries already included. ALSO - Velcro strips (stick on) for each unit included. BREAKDOWN: I paid $8 for 4 Hygrometers. Shipped! Plus I got: • FREE Batteries. (4) 2-packs would cost at dollar store = $4 • FREE Velcro tape. Would cost at dollar store = $1. • Shipping = Free (How much would that cost?) *Note: Let them sit for a while before saying they arent accurate. They respond slow, but steady. For the $$? No-brainer. I mean, chances are youre checking these periodically. Not every minute. Right?

These work well, are small and unobtrusive, and come with batteries.

These temp/humidity gauges are perfect for what I need them for, my praying mantis enclosure. So beautifully simple & cheap, but not poor quality! These are very sturdy & very easy to place due to being small. But not so small that you cant read the screen. They are perfect.
