The LogTag UTRED30-WiFi dual probe temperature recorder kit comes complete with the UTRED30-WiFi data logger, two ST100 probes and glycol bottles, including a NIST traceable calibration. The logger automatically uploads real-time temperature data from its connected external probes to your LogTag Online cloud account via your existing wireless network. It can also store up to 16,000 real-time temperature readings per channel, features a large easy-to-read display and is designed to show ‘at a glance' if temperature excursions have occurred during the current day and up to the previous 29 days. If temperature readings are outside pre-set alarm limits, it is indicated by a large X on the display and a blinking red alert LED. Alerts will be sent from LogTag Online to registered users. A built-in buzzer will optionally sound an audible alarm. The logger can also be used with just a single probe.
