Suggestions for temp/humidity gauges?

[MyKuLoO]

Hello,

I'm keeping a jungle carpet python and would like to suggestions on good temperature and humidity gauges. I am currently using Acurite temp/humidity gauges from Walmart.

Purchase the AcuRite Digital Humidity and Temperature Monitor for less at Walmart.com. Save money. Live better.

I have 1 on each side of the tank. However, they don't seem to be super accurate. Sometimes I see the humidity go as low as 16% which I know is not true based on other hydrometers I got in the tank.

Please make suggestions with links or places to purchase them.

Thanks!
