Product Description
Honeywell TM005X Wireless Thermo-hygrometer
Amazon.com Product Description
The Honeywell TM005X Wireless Thermo-Hygrometer is an easy-to-read and economical way to track temperature and humidity in your home or office. Featuring a jumbo display unit with one-inch tall digital numbers, this sleek silver and black unit can monitor up to three remote locations. The TM005X comes with one remote sensor, but two additional sensors can be purchased separately and added. With the main display unit measuring 4.33 x 4.86 x 1.08 inches (WxHxD), and a display that includes comfort and trend indicators, you can place the TM005X on your desktop or hang it from a wall. With the remote sensor, you can track the temperatures of pools, hot tubs, spas, ponds, soil, and much more. The remote sensor has a transmission range of up to 100 feet. With the sensor powered by two AA lithium batteries, the unit has an outdoor temperature range of minus 38 to 158 degrees Fahrenheit, and when the sensor is powered by two AA alkaline batteries, the range is minus 4 to 158 degrees Fahrenheit. (The two AA batteries required for the sensor, and the two AA batteries required for the main unit, are not included.)

 Accurate! May 29, 2008

I was most interested in the humidity measurement. I conducted a calibration****(See update at end of review) with a sling psychrometer. A sling psychrometer measures wet bulb/dry bulb temperature and is the least expensive (albeit a bit tedious to use) and most accurate way to determine relative humidity (RH).
I needed to know relative humidity for curiosity indoors and for a chamber in my basement used to dry cure sausage (I needed a 70%RH environment). The Honeywell unit was spot on with the sling psychrometer (and temp. was accurate as well).
The unit is new; I need to check it over time for accuracy. However, it's running very well so far and the price is right. I'll be buying more remote sensors [...] I found the remote sensor part no. is TS33C, can find them on Amazon with that search).
The majority of complaints say the humidity is "off." However, I didn't see a single valid calibration conducted.
Update 01-March-2009
I just took the main unit, the sensor and sling psychrometer. The conditions in my home at time of testing were 68F and 30% relative humidity.
Main unit read 68.4F/30% RH
The Sensor: 68.0F/30% RH
Sling Psychrometer: 68F/31% RH
The sling psychrometer consists of two sealed thermometers and will never need a calibration, it is an accurate standard. This Honeywell Unit is pretty darn good.
Update 13-Dec-2009
Someone contacted me and corrected a big point. I did not calibrate the unit by adjusting it to a known standard, I simply compared the values. My apologies for this rather serious error.
Excellent Product November 22, 2008

As an engineer, I am particular about accuracy. Some others have complained about differences between the temperatures and humidity reported by the base and remote when left adjacent to each other. I recognize that the base and remote can have different response time and under varying conditions could be expected to report different numbers even when next to each other. So I decided to perform an informal test. I placed the base and remote in a large picnic cooler with a gallon jug of water (for its thermal mass) and waited about 24 hours for everything to come to equilibrium. The temperatures were then identical between the base and remote and the humidity readings were an indicated 5% different. To take the readings I had to open the cooler. A better test would be done by cutting a window in the cooler and taking readings over time without disturbing the sealed environment surrounding the base and remote.
The temperature readings were accurate to about 0.5 degrees of a bulb thermometer that I trust to be accurate. The humidity readings made sense and a difference of only an indicated 5% I think is very good for an inexpensive instrument.
I like that the display can be set to alternate between the base and remote readings. I like the large numerals. I am able to leave the remote out on a screen porch and read the data upstairs. For home use, I don't think this product could get any better.

This thermometer/hygrometer has a large, easy to read display. I bought this primarily for the hygrometer and it's proven to be sensitive and accurate, both indoors and out. The product comes with a wireless outdoor (or other location) sensor that is easy to set up. You can add two additional sensors (not included). Although it's designed to sit on a table or shelf, it can also be hung on the wall. This might affect the hygrometer's sensitivity since the sensors are on the back. Haven't tried the wall mount.
Great thermo-Hygrometer at great price January 12, 2007

Works well except for slight differences in temperature and humidity between base and remote unit. Remote sender is being used for reporting conditions in my greenhouse. It serves that purpose very well.
It is a real bargain also.
simple but does the job March 15, 2007

I purchased this sytem to monitor the humidity in a basement from the main level. It works great and the base system allows several other remote stations to make keeping track of temperatures and humidity simple.
