Inexpensive, accurate hygrometer?

I hope this is the right forum for this thread. I want to get a hygrometer - I'm pretty sure I'm going to need two before long, actually - but I've been dropping a lot of coin on grow stuff lately and I need to try to save some $.

I was looking at a ThermoPro, but there were a lot of reviews saying that the accuracy of the humidity reading was off by 10%+. I guess the question that I should be asking is, how much do I need to spend to get a hygrometer that's "good enough?"

I'm looking for accurate jar hygrometers myself, I've tried a few but they were all totally inaccurate. I have a vivosun cheapy model for my room and it always exactly matches up with my dehumidifier, so I think that's a decent option in the $10 range.

Go on amazon, get like 3 ten packs of the cheapo's, then go through them all and pick the 10 that are most accurate and return the other 20. lol Thats what I did.

Genius lol

Keep in mind, some are very slow to respond, could lead to the impression of inaccuracy. I compare them to my Inkbird controller which has near instant response time.

I have two of these, slow but very accurate.

Bought a 5 pack of these. Can't recall about all 5, but the one I'm using atm is very accurate and fairly fast.

I think this one is off a bit but not bad. I have to find the instructions every time to change between degrees F or C.

I rely on HyLids and Caliber IV's. When used in conjunction, the curing jar, they always agree with each other.
