See both the current temperature and historical min and max temperatures.
The LogTag is so simple to set up and use that you'll be an expert in no time. We have a full LogTag training program on our site.
The LogTag UTRED30-WiFi is a temperature data logger that wirelessly uploads real-time temperature readings directly to your LogTag Online cloud account using your existing Wi-Fi network.
It includes a large, easy-to-read display and retains the trusted features of the LogTag range, such as non-volatile memory capable of storing up to 16,129 temperature records. It also offers a 30-day statistical memory, recording daily maximum and minimum temperatures as well as alarm durations.
This model of LogTag is extremely versatile.
| Product Model | UTRED30-WiFi |
| External Sensor Measurement Range | -40°C to +99°C (-40°F to +210°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 (±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. |

If you need some form of certification about the accuracy of your logger, you have various options.
This is a free certificate that comes with every LogTag. You can access this certificate through the configuration page in LogTag Analyser.
This paid certificate is from a laboratory that uses testing instruments that have been calibrated using NATA-traceable instruments.
This paid certificate is from a laboratory that has full NATA certification.
Latency, when it comes to temperature logging, refers to the delay between a change in temperature and when that change is detected and recorded by the logger. This delay can be due to the sensor’s design, the materials it’s placed in, or the logging interval. While it might sound like a disadvantage, latency can actually serve a useful purpose in certain environments—particularly where short-term temperature spikes are common but not harmful.
For example, in a busy commercial fridge, the temperature may briefly rise every time the door is opened. A logger with high latency won’t immediately react to these short fluctuations, helping to avoid unnecessary alarms or false data indicating a problem when there isn’t one. In these cases, a slight delay in response acts like a filter, focusing attention on real issues—such as prolonged exposure to unsafe temperatures—while ignoring the everyday ups and downs that don’t affect product quality or safety.
Depending on the type of logger you have, connecting your logger to your PC means either:
First Generation LogTags use a separate Reader (sometimes called a dock) for configuration and for downloading recorded data.
The Second Generation loggers only require a USB port or cable. Apart from saving the cost of the Reader, this makes them much better suited for shipping, because the recipient doesn’t need a LogTag Reader to download a report about the shipment’s journey.
