Loggers from vaccines to dry ice
The USB models create a PDF report without software, and models with a display show any deviations directly on the screen.
Products
LogTag loggers are designed in New Zealand. According to the manufacturer, they are used by organisations including the World Health Organization (WHO), UNICEF and Médecins Sans Frontières. The range includes single-use and reusable loggers and external probes from −90 °C to +99 °C.
The loggers are used in vaccine and medicine refrigerators, cold chain transport and dry ice shipments. UTRID-16 is WHO PQS prequalified. We supply LogTag loggers for all of these applications in Finland. If you are interested, request a quote.

Frequently asked questions
If you cannot find an answer, call +358 10 841 1600 or email asiakaspalvelu@diagnostica.fi.
Is software needed to read the logger?
Not for the USB models (UTRED-16F, UTRID-16 and UTRIX-16): they create a PDF report themselves when connected to a computer. TRED30-16U and TREL30-16U create PDF and CSV reports via a USB-C port, and SRIL-16U and TRIL-16U via a USB-A connector. The WiFi models send measurements to LogTag Online and also create a PDF report via micro-USB. The other models are read with the LTI-HID cradle and the free LogTag Analyzer software.
What are the CP and U models?
The CP models (TRED30-16CP and TREL30-16CP) take a Smart Probe, which is calibrated separately, so the logger itself can stay in place. The U models (TRED30-16U and TREL30-16U) have a USB-C connector, memory for 17.526 readings and a 60-day summary on the display, and they also work with a Smart Probe.
What does WHO PQS mean?
WHO PQS is the World Health Organization prequalification for vaccine cold chain equipment. UTRID-16 is prequalified under E006/076 and also complies with EN 12830.
Can the battery be replaced?
All models in the TRED30-16 and TREL30-16 series and UTRID-16R have a user-replaceable CR2032 battery. The WiFi models run on a mains adapter, with two replaceable AAA batteries as backup. The other USB models and the dry ice loggers have a built-in battery with a service life of 1–3 years depending on the model.
Which probe do I need?
ST100 probes measure −40…+99 °C and fit the TRED30-16 series, UTRED30-WiFi and UTRED-16F. ST10 probes measure −90…+40 °C and fit the TREL30-16 series, UTREL30-WiFi and TREL-8. Cable lengths are 0.5–3 metres. Smart Probes: CP110K for TRED30-16CP, CP100K for TRED30-16U, CP11S for TREL30-16CP and CP10S for TREL30-16U.
Is a calibration certificate available for the logger?
The TRED30-16R and TREL30-16 vaccine kits include a NIST-traceable calibration certificate. Ask us about certificates for other models.
