LogTag® TREL-8 Ultra-Low temperature data logger with external probe

Applications

Monitoring of articles stored at very low temperatures such as in dry ice type environments, where a remote probe is beneficial.

Product Summary

The LogTag® Low Temperature Remote Probe Recorder measures and stores up to 8000 temperature readings over -80 °C to +40 °C measurement range from associated interchangeable LogTag® ST10 type remote probe temperature sensor (available in lengths up to 3 meters).

Intended for use in monitoring of articles stored at low temperatures such as in dry ice type environments.

Using the LogTag® Interface and LogTag’s freely available companion software LogTag® Analyzer, the LogTag® is easily configured for recording conditions including delayed start, sampling interval, 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.

Product Highlights

  • Alert indicator – indicates if readings are outside of preset limits
  • OK indicator indicates if still recording and if readings within configured limits
  • Inspection mark in log by push button
  • Push Button Logging start
  • Rapid Download! Takes only seconds to download recordings
  • 'Pre-Start' logging - Logtag® can be configured to record even if it has not been started.
  • High performance at low cost
  • Credit card sized case – thin enough to be easily mailed “letter rate”.
  • Real time clock records time & temperature simultaneously
  • 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
  • High quality gold plated remote sensor connector
  • Interchangeable Probes – LogTag® remote temperature probes are interchangeable.

Technical Specifications

Part Order Code TREL-8
Remote Probe Temperature Sensor measurement range (ST10 type only) -80 °C ~ +40 °C
Recorder operating temperature range -30 °C ~ +70 °C
Rated Temperature reading accuracy

Better than ±1 °C for -30 °C~ +20 °C

Opciones de Sonda Remota

LogTag® TREL está diseñado y calibrado para su uso con el sensor de temperatura remoto LogTag® ST10S. Sólo esta sonda es compatible con TREL y el uso de cualquier otro tipo de sonda puede causar un error en las lecturas.

Los sensores LogTag® ST10S están diseñados y calibrados para que puedan intercambiarse con los registradores TREL con la precisión nominal estándar del producto. Si una combinación de sondas TREL/ST10S se calibra con un mayor nivel de precisión (como es posible), se debe tener cuidado de utilizar siempre la misma combinación TREL/ST10S para las mediciones, ya que el sensor ST10S no es intercambiable con mayor precisión que el valor nominal de TREL/ST10S de la presente especificación.

Identificación de una sonda ST100

La sonda ST10S se distingue de otros tipos de sondas de temperatura remotas LogTag® por el color verde de la vaina en el conector del sensor.




ST10S-05 (0.5 m)
ST10S-30 (3 m)

Sonda de punta corta

La sonda con punta incorpora una sonda de 22 mm de longitud expuesta de 5 mm de diámetro exterior de acero inoxidable 316 sin mango pero con un pequeño sobremolde para mejorar la resistencia a la humedad y proporcionar alivio de la tensión del cable. Todos los materiales en el extremo de la sonda de cable son aptos para alimentos según la FDA, incluyendo el cable.

Suministrado estándar (parte# ST10S-05) con 0.5m o extendido (parte#ST10S-30) con 3m de cable terminado en el conector MCX para conectarlo a LogTag® TREL.


STX-50
STX-50 (5.0 m)

External sensor extension cable

The STX-50 is a 5 meter (~16’ 5”) extension cable for extending ST10 or ST100 external temperature sensors.

The socket end of the cable (which accepts the ST100 or ST10 sensor plug) is fitted with a flexible sleeve that when the ST sensor’s plug is in place will protect the mated connection to IP61.
