Ultra-Low Freezer Temp Data Logger with Interface Cradle, NIST

The TREL30-16 Data Logger is the ultimate solution for precise ultra-low-temperature monitoring, perfect for freezers storing blood plasma, vaccines, pharmaceuticals, and more. It operates within a temperature range of -90°C to +40°C (-130°F to +104°F) using an external probe, making it ideal for tracking vaccines like Pfizer and BioNTech, which require storage at -70°C (-94°F).

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

The built-in alarm system triggers if temperatures exceed pre-set limits, switching the status indicator from ✔ to X. An optional audible alarm and a day marker highlight any temperature excursions. While the alarm sound and indicator can be reset, the day marker remains to ensure excursions are recorded.

Users can review detailed excursion data from the last 30 days directly on the device or download comprehensive data using the LogTag® Interface cradle and LogTag® Analyzer software. Simplified functions for clearing alarms, as well as stopping and starting recordings, make the TREL30-16 easy to use and highly reliable.FEATURES:

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).
