Extech 445815 Humidity Alert II Hygro-Thermometer

Damage resulting from high humidity and poor ventilation in storage rooms, offices, and houses give rise not only to millions worth of costs but are also unhealthy and unsightly. Most people think that the dampness comes from outside, but that is often not true. In reality, moisture is caused inside the house by evaporation in the kitchen and bathroom. The use of highly insulating building materials greatly reduces ventilation which means that active ventilation is now a necessity. It is therefore important to check the indoor climate in order to ensure a healthy living environment. The Extech 445815 Humidity Alert II Hygro-Thermometer alarms you when the %RH exceeds a pre-set HI or LO limit. The remote probe conveniently mounts on the meter or extends for measurements in ducts or remote locations. It also features Humidity and Temperature adjustments. The unit can be wall-mounted or placed on a flat surface using the fold-out stand. This professional meter, with proper care, will provide years of safe reliable service.
