Reliable Temperature Data Logging

LogTag Temperature Data Logger

Versatile wide range data logger

The LogTag Temperature Data Logger is a versatile wide range logger providing users with a tool to record and download data points over an extended period. Minimum, maximum points and logging intervals can be setup with ease using the LogTag software. Delayed starts cab also be set with the user only needing to press ‘START’ button on the front of the unit to trigger logging to commence. An ‘ALERT’ LED light is located on the front of the logger, which is triggered if any measurement taken is outside the acceptable limits. Significant events, such as the door of a refrigerator being opened for an extended period can also be ‘Marked’ by pressing the ‘MARK’ button on the unit.

Readings are downloaded using the LogTag Analyser Software, which provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as Excel. For further information regarding the software click here.

The LogTag Temperature Data Logger complies with the relevant international standard for temperature monitoring devices such as FCC, CE, C-Tick and RoHS.

Product Model  TRIX-16
Sensor Measurement Range             -40°C to +85°C
Operating Temperature Range -40°C to +85°C
Storage Temperature Range -30°C to +55°C
Rated Temperature Reading Accuracy                                                                                  

 Better than ±0.5°C for -20°C to +40°C. Better than ±0.7°C for -30°C to -20°C and +40°C to +60°C. Better than ±0.8°C for +60°C to +85°C. Better than ±0.9°C for -40°C to -30°C. Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below. Accuracy figures can be improved by recalibration.

Rated Temperature Reading Resolution

 Less than 0.1°C for -40°C to +40°C. Less than 0.2°C for +40°C to +80°C. Less than 0.4°C for +80°C to +85°C. Please see the Rated Native Resolution chart below. LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®.

Sensor Reaction Time

 Typically, less than 5 minutes (T90) in moving air (1m/s).

Recording Capacity

 16,159 temperature readings. 112 days @ 10min logging, 168 days @ 15min logging.

Sampling Interval

 Configurable from 30 seconds to several hours.

Logging Start Options

 Push button start or specific date & time. Optional start delay of up to 18hours.

Recording Indication

 Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator.

Download Time

 Typically, less than 10 seconds for full memory (16,159 readings), depending on computer or readout device used.


 IP65 (roughly equivalent to NEMA 4)

Power Source

 3V Li-Mg Battery

Battery Life

 2 – 3 years of normal use (based on 15-minute logging, download data monthly)

Real Time Clock

 Built-in real time clock. Rated accuracy ±25ppm @ 25°C (equivalent to 2.5 seconds/day). Rated temperature coefficient is -0.034 ±0.006ppm/°C (I.e typically +/- 0.00294 seconds/day/°C).


 86mm(H) x 54.5mm(W) x 8.6mm(T)
