Logtag TRED30-7 External Probe Temperature Logger With Display

TRED30-7-withExtProbe-small

An economical option for monitoring refrigerators, incubators, cold rooms, etc where the sensor is located inside the chamber and the logger with display outside, LogTag TRED30-7 Temperature Recorder measures and stores up to 7770 temperature readings over the temperature range of -40°C to +99°C. The device features a large display that allows one to review if temperature violations have occurred in the last 24 hours and this can be done ‘at a glance’ for the previous 29 days also. The display shows the current temperature reading, the current time, recording status and battery status.

A special feature of this device is the ability to view at a glance, the day numbers when there was an alarm excursion. One can then, using the Review button, review the minimum and maximum values for the days in question or for all the last 30 days for which data has been recorded.

Two different battery options are available. TRED30-7R has a user replaceable battery with typical battery life of 1 year. TRED30-7F has a non user replaceable battery with typical battery life of 2-3 years.

  • Day alarms summary – Displays, in calendar-like format, alarm triggers for up to the last 30 days
  • Rapid Download! Takes only seconds to download recordings
  • Push Button Logging start with optional delayed start or specific Time & Date start
  • Pre-Start logging – Logtag can be configured to record even if it has not been started.
  • Thin flat case – Fits easily into packaging and thin enough to be easily mailed “letter rate basis”
  • Interchangeable Remote Probes – LogTag® remote temperature probes are interchangeable provided they are changed with LogTag® ST100 type remote temperature sensors.
  • 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 formats compatible with other applications such as Excel
  • Re-calibration to achieve higher accuracy possible
