Digital & Wireless Thermometers & Barometers

Digital thermometers offer easy-to-read displays and affordable pricing. Often including indoor/outdoor temperature, min/max memory and barometric pressure measurements.

Digital thermometers have the advantage of being able to send and record data automatically and many are able to accept the inputs from multiple temperature sensors. This feature allows for the addition of specialized thermometers, such as those with temperature probes allowing you to monitor a pool or hot tub. A remote indoor thermometer can also be used to monitor wine cellar temperature or the temperature in another location in your house.
