Indoor Good wireless thermo/hygrometers for the grow room?

[nomis]

I'm shopping around for a new wireless thermo/hygro meter for my grow room. The one I have now is just too slow to adjust to new temp's and humidity, for example it's taken almost 45 minutes to fully adjust from the 30c grow room to -4.5c sitting outside. As my closet can get hot quickly I need a meter that adjusts quickly.

Am curious what decent models you guys are using?

I use this one except mine is an older model. Had it about 4 years and have never even changed the batteries. Honestly, I don't know how quick it updates though. I have never paid that much attention to it. It just works every time I look at it.

hey man i use the same meters in my tent/grow room that i use for curing...Amazon.com - CALIBER IV DIGITAL HYGROMETER 4 CIGAR HUMIDOR

these seem to update right when the temp changes..if i turn off the window ac unit in my room the temps jump up on the meter immediately :smokebuds:
