LogTag USRIC-4

Single-use USB Temperature Logger

Single-use USB Temperature Logger


  • Integral USB connector - no separate Interface Cradle required.
  • Up to 4,000 real time temperature recordings.
  • Automatically generate a PDF report using the USRIC-4 PDF generator.
  • A real time clock provides date/time stamps for each temperature reading.
  • Customize start options, logging interval, alert parameters and many more.

The LogTag® USRIC-4 combines all the features of an advanced temperature recorder with 4000 log memory and a 6-month operating life in a robust and inexpensive package.

Readings are downloaded using 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.

Desinged as a Single-use, cost effective & reliable temperature recorder, the LogTag® USRIC-4 measures and stores real time temperature readings over a measurement range of -30 °C to +60 °C.

The USRIC-4 plugs directly into the computer USB for easy configuration by the user for a wide range of recording and alert conditions.

A red Alert indicator provides an immediate indication - without access to a PC - if any readings are outside the limits specified at the time the unit was configured. A green OK indicator provides immediate visual confirmation that the unit is operating.
