Hi, ( Thank you ........Tyson and Morgan )
I have spent more $$ hygrometers than ANY other supply for my enclosures.
Shortly after the post regarding these , I purchased one........Ambient Weather Station Model WS-1175
It has been really terrific!
I am going to purchase additional thermometers, as I think it will receive up to four.
And it's wireless !!!!!!!! The thermometers can be easily moved around inside the enclosure.
Plus, I made the mistake of purchasing two receivers ( 2 sets) . Rather than sending one back, I have one running in the kitchen ( monitoring the enclosures in the basement !!!) There is little button on the front of this model that switches from one thermometer being received to another.

The button that switches from one therm. to another is in the lower R hand corner.
#1 is my red eye enclosure ( mist king just sprayed ) .
I still have to set the time, day and date.
