TempMinder 4-Zone Temperature and Humidity Station - MRI-333MX

Average Customer Rating:  4.5 out of 5 stars   (2 Customer Reviews)

- MRI-333MX

We purchased a new travel trailer and as "newbees" we learned dampness due to humidity was not good so I picked out this unit from etrailer.com, I strategically placed 3 sensors [including the monitor] inside the trailer and one in the lower storage bay out front. So with my monitoring system in place along with my bucket of damp rid, I'm good to go. 906175

After going on line to see why the receiver was not working, I found that the low cost batters I had put in the receiver would not work. This was something that was not in the instructions. Other than that it seems to be working. 784529
