This alerts users to adverse conditions, which can help users avoid mold caused by high humidity, as well as static electricity caused by low humidity. Comes with one-year limited warranty. Unlike other humidity indicators, this meter calculates and displays the Dew Point reading, which is a calculation of temperature and humidity and used to determine when condensation will occur. The 445814 has a built-in sensor and measures humidity from 10 to 99 percent RH and temperature from 14 to 140 degrees F (-10 to 60 degrees C) with an accuracy of 4 percent RH; 1.8 degrees F.</p></div> <h5><div id="header2">What's in the Box</div></h5> <div id="text2" class="a-spacing-small"><p>Extech 445814 Hygro-Thermometer Humidity Meter with built-in stand, wall mount bracket, two AAA batteries, and user manual.</p></div> <div class="break"></div> <br> <div class="sixth-col"> <div class="centerImage"> <div id="image1"><img src="http://ecx.images-amazon.com/images/I/11H4iRjp+BL.jpg" alt="" ><div class="imageCaption">445815 <br>View larger</div></div> </div> </div> <div class="third-col"> <h5><div id="header3">Hygro-Thermometer Humidity Meter</div></h5> <div id="text3" class="a-spacing-small"><p>The 445815 has a remote probe that can either clip onto the meter or extend on an 18-inch cable, enabling you to take measurements behind walls, in ducts, or other areas that are difficult to access.
