Software-less temperature measurement with built in USB-C connection an 60 day display.
Elevate your vaccine storage practices with the LogTag TRED30-16U! This enhanced, software-less data logger builds on the success of the best-selling TRED30-16, now with the new, built-in USB-C connection to complement the existing 3-pin cradle connection.
Designed for ease of use, the TRED30‑16U boasts a new, simplified LCD that displays minimum and maximum temperature values and offers a quick overview of temperature excursions over the past 60 days. This allows you to ensure the integr i ty of your vaccines with confidence.
The LogTag TRED30-16U Temperature Logger measures and stores up to 17,526 temperature readings over a -40 °C to +99 °C (-40 °F to +210 °F) measurement range
It complies with the guidelines of vaccine storage and handling from CDC, FDA, VFC, NIH, PHAC, AAP and more.

| Product Model | TRED30-16U (Replaceable Battery) |
|---|---|
| External Temperature Sensor Measurement Range | -40 °C to +99 °C (-40 °F to +210 °F) |
| Recorder 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 (±0.9 °F) for -20 °C to +40 °C (-4 °F to +104 °F), typically ±0.3 °C (0.6 °F). Better than ±0.8 °C (±1.4 °F) for -40 °C to -20 °C (-40 °F to -4 °F), typically ±0.5°C (0.9°F). Better than ±0.8°C (±1.4 °F) for +40 °C to +70 °C (+104 °F to +158 °F), typically ±0.7 °C (1.3 °F); Better than ±1.2 °C (±2.2 °F) for +70 °C to +99 °C (+158 °F to +210 °F), typically ±1 °C (1.8 °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 -40 °C to +50 °C (-40 °F to +122 °F); 0.2 °C (0.4 °F) for measurements +50 °C to +70 °C (+122 °F to +158 °F); 0.3 °C (0.5 °F) for measurements +70 °C to +80 °C (+158 °F to +176 °F); 0.4 °C-0.6 °C (0.7 °F to 1 °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. The native resolution is what is stored in the LogTag |
| Recording Capacity | 17,526 temperature readings. 60 days @ 5min 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 18 hours |
| Logging Start Options | Push button start or specific date & time. Optional start delay of up to 18hours |
| Recording Indication | State indicator “REC” |
| Download Time | Typically less than 10 seconds for full memory (17,526 readings), using USB connection, depending on your computer |
| 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) |
| Size | 93 mm(H) x 54.5 mm(W) x 8.6 mm(T) |
| Weight | 43 g |
| Case Material | Polycarbonate |
| Standard External Probe Cable Lengths | Standard: 1.5m (4’11”). Extended: 3 m (9’10”) (recommended maximum) |
