The KeyTag KTL-108-D temperature recorder features a display together with a data logging function storing up to 7770 temperature readings. Statistical temperature and duration readings for up to 30 days can be reviewed on the display. The visual display of current temperature and previous alarms is an important feature in “static” applications such as cool rooms and refrigerators. The KTL-108-D can also be used in transit applications where a direct readout of the statistical data is required without use of a computer or readout device. The display arrangement is designed to show ‘at a glance’ if temperature violations have occurred during the current day and up to the previous 29 days. The display also shows the current temperature reading, the current time, recording status and battery status. Details of any violations excursions can be checked directly by inspecting the statistics history on the recorder’s display or in more detail by downloading the logged data. If a reading outside the pre-set “Alarm” limits is recorded at any time, a “day alarm indicator” appears on the display. Logged data can be downloaded via a standard KeyTag Interface to the free companion software Keyag Analyzer which provides facilities for displaying data in chart, table or statistical formats and allows electronic archiving, export or transmission of the data in support of sophisticated data management systems. The recorder incorporates an external temperature sensor uniquely arranged in a recess in the case.
This arrangement protects the sensor from physical damage while retaining the faster response time normally associated with remote sensors. The recorder can be configured to suspend processing of readings for alarms and max/min statistics for a period of time after button press activity. This allows the user to review the current statistics or clear an alarm without causing a false alarm or statistic while handling the recorder.
