TREX-8
Temperature data logger with external probe -40°C to +99°C
All standard temperature recording applications where an external probe is beneficial.
The LogTag® TREX-8 is a versatile, wide range, multitrip Temperature Logger with interchangeable External Probes, featuring high resolution temperature readings
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.
Applications
Cold Chain – Pharmaceuticals – Produce/Meat/Dairy – Agriculture & Floral – Office & Warehouse – Museums – Chemicals – Laboratories – Server room – Clinical trials

| External Sensor Measurement Range | -40°C to +99°C (-40°F to +210°F) |
| 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 for -10°C to +40°C. Better than ±0.7°C for -10°C to -30°C and +40°C to +60°C. Better than ±0.8°C for -30°C to -40°C and +60°C to +80°C. Better than ±1.0°C for +80°C to +99°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 0.6°C for +80°C to +99°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®. |

| Recording Capacity | 8031 temperature readings. 53 days @ 10min logging, 80 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 18 hours. |
| Recording Indication | Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator. |
| Download Time | Typically less than 5 seconds for full memory (8031 readings), depending on computer or readout device used. |
| Environmental | IP61. |
| 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). |
