Customer Questions & Answers

is there an outside piece that picks up the temp and humidity and transmits it to the indoor thermometer?

trying to find a thermometer that also reads the in and out temps and humidity.
Asked by: kcorn
Yes, the satellite sensors (up to 3 of them) can be used outdoors. I purchased this same product over twenty years ago (from Radio Shack, sold with their name on it) and it is still working great! I have three sensors and the main unit (shown above) scans the three remotes every 30 seconds. I have one outside, one in our basement and one upstairs in my office.

Are other sensors avalable?

Are additional sensors available and if so, what are the part numbers and prices? Can they be ordered with the unit?

Is this a daily or weekly Min/Max memory.

Asked by: snp32
The time span of the Min/Max function depends on when you last reset the device (using the Mem/Clear button). You can clear it every day, every week, before you go to bed, whatever you want).

Wireless Digital Thermo-Hygrometer with 1 Remote Sensor and 90 ft. Range is rated 4.1 out of 5 by 7.
Rated 5 out of 5 by from Works as advertised. Works as advertised.

Rated 4 out of 5 by from Like the form and function of this hygrometer I have four different hygrometers and this one is my favorite because of it's simple to use features, look and the remote unit that tells the humidity/temp in another room. All the hygrometers read within +/-5% of each other, plus when I move them around the apartment they slowly change to reflect what the other hygrometer was reading +/-5%. Not too bad. The little "frown" face shows up when it's below 40% humidity which is a nice touch.

Rated 5 out of 5 by from Easy setup and convienent to monitor. I used this with 2 additional remote sensors. It performs great. It can receive the 3 sensors in the attic with the main unit on the 2nd, 1st or basement levels.

Rated 5 out of 5 by from Easy to install. Simple to install and monitor remotely. Wish it had a 24 hr display of hi/lo readings.

Rated 1 out of 5 by from Piece of Junk Easy to setup. Routinely reads no temp or hydro and when it does it is off by close to 10 degrees. Have a much more reliable oregon scientific that jibes with a la cross. I can't say enough about not wasting your money on this product.

Rated 4 out of 5 by from Overall a Great product! I have minor suggestions for improvement, but very happy overall. I am very satisfied with this product. Some things i would like to see done better is that it seems to get out of sync if the remote temp/humid. sensor power is removed. The fix is easy... just take the batteries out/put back into the receiver unit. Just seems a tad clunky of a fix, but not a big deal. I will admit i didn't read the manual, so maybe i'm doing something wrong. The other thing (which maybe i'm alone on this one) is that i would like to see the remote sensor unit have an optional power-pack input jack. Mine is being used to monitor humidity levels in my crawl space, and i really don't enjoy going down there any more than i have to, so i jerry-rigged my own power pack to keep it powered up all the time, but would have been nice to have this as an option without having to bust out the soldering iron. :) On the positive side, it maintains min/max for temperature and humidity both locally and on the transmitter unit on up to 3 different remote units. So far, i'm extremely happy with this product, and it is meeting my needs nicely.

Rated 5 out of 5 by from Perfect I use this system for my well pit to make sure my temperature does not drop below freezing during the winter. I am very pleased.
