The LogTag® UTREL30-16 Dual-Channel Low Temperature Recorder measures and stores up to a total 32,000 temperature readings.
It 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.
The alarm is triggered if temperature readings are outside pre-set alarm limits which is indicated by a large X on the display and, if configured, the audible alarm will sound.
(Silica sand recommended for temperatures below -40ºC for Buffer Assembly)
