LogTag TREX-8

Multi-use Logger for any Industry

Multi-use Logger for any Industry


  • ‘OK’ & ‘ALERT’ Indicator with high and low customizable alarms.
  • 8,000 reading memory capacity with up to 3 year battery life
  • Industry best download time – less than 5 seconds for full memory.
  • Re-calibration to achieve higher accuracy possible
  • High quality gold plated remote sensor connector
  • Interchangeable Probes – LogTag® remote temperature probes are interchangeable.

Using the LogTag® Interface and the freely available companion software LogTag® Analyzer , the LogTag® is easily set-up for recording conditions including delayed start, sampling interval, number of readings, continuous or fixed number of readings and configuration of conditions to activate the ALERT indicator.

Readings are downloaded using LogTag® Analyzer which provides facilities for charting, zooming, listing data statistics and allows exporting the data to other applications such as Excel.

The LogTag® Remote Probe Temperature Recorder measures and stores up to 8000 temperature readings over -40 °C to +99 °C measurement range.

Please note: An interface is required for configuration and reporting

Product Model TREX-8
Recorder operating temperature range -40 °C to +85 °C (-40 °F to +185 °F)
Storage Temperature Range -10 °C to +55 °C (14 °F to +131 °F)
Rated Temperature reading accuracy Better than ±0.5 °C (±0.9 °F) for -10 °C to +40 °C (14 °F to +104 °F). Better than ±0.7 °C (±1.3 °F) for -30 °C to -10 °C (-22 °F to 14 °F) & +40 °C to +60 °C (104 °F to 14 0°F). Better than ±0.8 °C (±1.4 °F) for -40 °C to -30 °C (-40 °F to -22 °F) & +60 °C to +80 °C (140 °F to 176 °F). Better than ±1.0 °C (±1.8 °F) for +80 °C to +99 °C (176 °F to 210 °F). Actual performance is typically much better than the rated values. Accuracy figures can be improved by recalibration
Rated Temperature Reading Resolution Less than 0.1 °C (0.2 °F) for measurements -40 °C to +40 °C (-40 °F to +104 °F). Less than 0.2 °C (0.4 °F) for measurements +40 °C to +80 °C (+104 °F to +176 °F). Less than 0.6 °C (0.5 °F) for measurements +80 °C to +99 °C (+176 °F to +210 °F). LogTag Analyzer® currently displays to one decimal place of °C or °F
Sensor Reaction Time Typically less than 2 minutes (T90) in moving air (1m/s) for ST100T, ST100H & ST100S types
Recording Capacity 8031 temperature readings. 53 days @ 10min logging, 80 days @ 15min logging
Download Time Typically less than 5 seconds for full memory (8031 readings), depending on computer or readout device used
Environmental IP61
Power source CR2450 3V LiMnO2 Battery (Fixed)
Battery Life 1 year storage, followed by 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)
Size 86 mm(H) x 54.5 mm(W) x 8.6 mm(T)
Weight 36 g (without External Probe)
Sampling Interval Configurable from 30 seconds to 18 hours
Logging Start Options Push button start or specific date & time. Optional start delay of up to 72 hours
Recording Indication Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator
Case Material Polycarbonate
External Temperature Sensor Measurement Range -40 °C to +99 °C (-40 °F to +210 °F)
