digital indoor - outdoor thermometer with alarm

This indoor outdoor thermometer is perfect for home/office and weather temperature measurement. The thermometer incorporates two temperature sensors, a small, water resistant, detachable remote probe with a three metre PVC lead for outside temperatures and an internal thermistor sensor to measure for indoor temperatures. The indoor outdoor thermometer also features a programmable high/low alarm to give you an audible warning if the temperature falls outside the ones you set (remote probe only). With a 5000 hour battery life the AAA batteries will only need changing every 6 months. The dual measurement thermometer features an easy-to-read dual LCD display and max/min function to view the highest and lowest temperatures. Indoor temperature is measured over the range of -19.9 to 69.9°C while outdoor is -49.9 to 69.9°C. Both have a resolution of 0.1 °C and an accuracy of ±1 °C.  The max/min thermometer is housed in an ABS case which incorporates a foldaway stand and a keyhole slot for hanging on the wall.
