The display is designed to show ‘at a glance’ if temperature excursions have occurred during the current day and up to the previous 30 days. The display also shows the current temperature reading, the current time, recording status and battery status.
The alarm is triggered if temperature readings are outside pre-set alarm limits. The status indicator changes from a ✔ to a X,the red LED is flashing and, if configured, the audible alarm will sound. The day marker will also appear if not already present. The alarm status indicator and audible alarm can be easily cleared, but the day marker remains to ensure a visible record of excursions is shown on the display. A simplified alarm clearance, stop & start procedure is available as an option.
Details of any excursion in the preceding 30 days can be checked directly by inspecting the statistics history on the recorder’s display or in more detail by downloading the logged data via a micro-USB cable to LogTag® Analyzer operating software.

Rated Temperature Reading Resolution |
Better than 0.1 °C (0.2 °F) for -30 °C to +60 °C (-22 °F to +140 °F). Better than 0.2 °C (0.4 °F) for -40 °C to -30 °C (-40 °F to -22 °F). Better than 0.5 °C (0.9 °F) for +60 °C to +99 °C (+140 °F to +210 °F). LogTag Analyzer currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag |

Temperature measurement where access requires a remote probe and data needs to be accessed without a PC. The LogTag UTRED30-16 DUAL provides the facility to create a detailed PDF report without need for extra accessories and proprietary software and features a display, allowing immediate viewing of current and past temperatures. It also has a display so that current and historical temperatures, as well as alarm statistics for the last 30 days, can be viewed instantly without a PC.
