Description

The ALTA Digital Temperature Sensor assesses the temperature of whatever environment the probe is in. At the push of a button, temperature readings are displayed on the device's digital display and sent to iMonnit software through a Monnit gateway(purchased separately), creating an easy-to-read log of current and past readings.
