Ultra-Low Freezer Temp Data Logger with Docking Station, NIST

The TREL30-16 Data Logger is designed for precise Ultra-Low-Temperature monitoring and recording, ideal for freezers storing blood plasma, vaccines, pharmaceuticals, and more. It operates within a range of -90°C to +40°C (-130°F to +104°F) using an external probe.

Perfect for tracking COVID-19 vaccines like Pfizer and BioNTech, which require storage and transport at -70°C (-94°F).

With a memory capacity of 15,900 temperature records, the TREL30-16 can log data for up to 66 days at 6-minute intervals. Its display provides an “At A Glance” view of temperature excursions for the current day and the prior 29 days. It also shows the current temperature, time, recording status, and battery level.

The alarm activates if temperatures exceed pre-set limits, changing the status indicator from ✔ to X. If configured, an audible alarm will sound, and a day marker will appear to highlight the excursion. While the alarm indicator and sound can be cleared, the day marker remains visible to ensure any excursions are recorded.

You can review excursion details for the past 30 days directly on the device or in greater depth by downloading data through the LogTag® Interface cradle using LogTag® Analyzer software. Simplified procedures for clearing alarms, stopping, and starting recordings are also available.

SPECIFICATIONS:

Product Model            TREL30-16 (Replaceable Battery).

External Sensor Measurement Range -90°C to +40°C (-130°F to +104°F).

Operating Temperature Range           -30°C to +60°C (-22°F to +140°F).

Storage Temperature Range   -10°C to +40°C (14°F to +104°F).

Rated Temperature Reading Accuracy            Better than ±0.5°C for -20°C to +10°C (-4°F to 50°F).

Better than ±0.7°C for -50°C to -20°C (-58°F to -4°F) and +10°C to +30°C (50°F to 86°F) .

Better than ±1°C for -80°C to -50°C (-112°F to -58°F ) and +30°C to +40°C (86°F to 104°F).

Actual performance is typically much better than the rated values.

Accuracy figures can be improved by recalibration.

Rated Temperature Reading Resolution         0.1°C (0.2°F) for measurements -80°C to 0°C (-112°F to 32°F).

0.2°C (0.4°F) for measurements 0°C to 18°C (32°F to 64.4°F).

0.3°C (0.5°F) for measurements 18°C to 30°C (64.4°F to 86°F).

0.5°C (0.9°F) for measurements 30°C to 40°C (86°F to 104°F).

LogTag Analyzer® currently displays to one decimal place of °C or °F.

The native resolution is what is stored in the LogTag®.

Recording Capacity   15,905 temperature readings. 66 days @ 6min logging. Day summary statistics memory (for display on LCD): up for 30 days of Max/Min/duration and alarm trigger statistics.

Sampling Interval        Configurable from 30 seconds to hourly.

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

Recording Indication   State indicator “REC”.

Download Time          Typically less than 10 seconds for full memory (15,905 readings), depending on computer or readout device used.

Environmental IP61 (when vertically mounted or hung).

Power Source  3V CR2032 (LiMnO2) coin cell battery, user replaceable.

Battery Life      1 year storage, followed by 1 year of operation with normal use

(6 minute logging, statistics reviewed on the display no more than once daily

for no longer than 30 seconds each time, download data monthly).

NOTE: Continual activation of the audible alarm will reduce the working life of the battery.

When an alarm is triggered, the alarm should be cleared and reset as soon as possible.

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).
