Review: Only in "Chinese" Not really useful. - Instructions for the product are not available in English nor in French. Only in "Chinese" Not really useful.
Review: The best you'll find. - This is a very good instrument displaying exactly what is relevant: Relative humidity, temperature and dewpoint. The dewpoint calculated from the other two is very useful to know but most other instruments show the time instead and who wants that on an instrument like this? The alarm functions and the max high and low recordings are useful as well. Designed by a respected instrument manufacturer by engineers with a vision. I lost my old one and had to find an exact match since nothing else could serve my needs any better.

### ⭐⭐⭐⭐⭐ Dew point display is helpful
*by J***S on 13 July 2008*

Dew point display was the feature that made me buy this product. It has worked well, has a long battery life, and is accurate. The dew point shows how much humidity I can safely add in the winter without condensation forming on the windows. It also indicates the efficiency of the air conditioner in the summer. "Delta T" (the change in temperature, the temperature of the intake air minus the temperature of the chilled air) shows how much heat the air conditioner is removing. Since the a/c also removes moisture, the dew point tends to be the same as the evaporator plates, which is the temperature of the chilled air. (Unless you live in a dry climate.) So, just noting the difference between the ambient air and dew point indicates the efficiency. It is amazing how much more efficient the a/c is in the morning, when the outside temperature is in the 70s versus how little chilling happens in the afternoon in the 90s. I quit running the a/c in the mid afternoon, and save a few buck on the electricity. It is a fine product. Spread the word about the dew point!
