LogTag® TRID30-7 :
Temperature Recorder with 30day summary display

The LogTag® TRID30-7 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 TRID30-7 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.

If a reading outside the pre-set “Alarm” limits is recorded at any time, a “day alarm indicator” appears on the display. A visual alarm trigger is displayed if one or more of the configured alarm trigger conditions have been met. An alarm trigger condition can be a single reading above the upper or below the lower threshold values, a set of consecutive violating readings or an accumulation of violation readings encountered.

Details of any violations can be checked directly by inspecting the statistics history on the recorder’s display or in more detail by downloading the logged data. Logged data can be downloaded via a standard LogTag Interface to the free companion software LogTag 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.

Two different battery options are available:-
Part# TRID30-7R : Equipped with user replaceable battery (CR2032) with typical battery life of 1 year.
Part# TRID30-7F : Fixed cell (non user replaceable) with typical battery life of 2-3 years.

Data Logging – Records time and temperature data for later download
Day alarm summary - Displays in calendar-like format alarm triggers for up to the last 30days
Current time & temperature - Shows the current time and temperature when not in review mode
Push Button Logging start with optional delayed start or specific Time & Date start
Rapid Download! Takes only seconds to download recordings
‘Pre-Start’ logging - Logtag can be configured to record even if it has not been started.
High performance at low cost
Thin flat case – Fits easily into packaging and thin enough to be easily mailed “letter rate”.
Real time clock records time & temperature simultaneously
Easy to use LogTag Analyzer software that runs on any PC configures LogTag for recording then downloads resulting data for analysis. Data can also be exported to fomats compatible with other applications such as Excel
Re-calibration to achieve higher accuracy possible
