Digital camera reviews of Honeywell TM005X Wireless Indoor/Outdoor Thermo-Hygrometer
Digital camera Review: Accurate
Summary: 4 Stars
I tested the main unit's accuracy using the Boveda One-Step Calibration and am pleased to say that it's spot-on accurate. The only drawback is the remote's temp and humidity reading differs slightly from the main unit. A difference of as much as +/-2.Digital camera Review: Accurate Little Bugger
Summary: 5 Stars
After a month of use and calibration, I can honestly say this is one of the finest hygrometer/thermometer units I've ever used. The range on the supplied remote unit is also superb (it's actually sitting in my basement while the main unit resides on the uppermost floor two storeys up), although it's accuracy appears to be slightly less than the main unit, as one would expect.
If you're looking for a good quality and yet inexpensive digital hygrometer, look no further!
Digital camera Review: Accurate and a great value!
Summary: 5 Stars
Both the base station and remote unit were reasonable accurate (tested against calibrated hygrometer). For < $25 you're getting two thermometer/hygrometers - so it's a great value. It would be nice if you could view more than one reading at a time, but as is the unit is easy to use and read.Digital camera Review: Accurate and easy to use!

I bought this product to use in my Baby's room to have an accurate reading of the temperature and humidity in it. I have been using it for a bit over a month now and have no complaints. It is VERY easy to set up and use and battery life seems to be excellent. It also has a remote sensor that you can place in any other part of the house or the exterior to monitor that area's temperature and humidity, also; although you don't HAVE to use it, only if you want to, as the main unit will work by itself.
Numbers are fairly big and easy to read from a distance. It will give you a nice smiley face whenever conditions on the monitored area are ideal. It has come very handy since my central air conditioner's thermostat is located on the main room of the house so the temperature reading will be that of this particular room, making it difficult to know what is the exact temperature on my baby's room; so with this Hygrometer now I know for sure the exact temperature on my baby's room and any parent out there know that this is a must for safety! From my personal experience with it, I would recommend this item hands down.
Digital camera Review: Accurate!
Summary: 5 Stars
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.
