Because this logger sits outside the super-cold environment, its battery life is the same as regular LogTags
If the temperature inside the package rises above the alert level, the red LED will flash, giving you a visual notification that there has been a problem.
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
Our probe-less Dry Ice LogTags are great for their convenience, but this probe model has its own advantages.
Importantly, you can get an instant gauge of the temperature inside the packaging – flashing red means there is a problem.
Also, battery life is better than the direct contact model.
| Product Model | TREL-8. |
| Sensor Measurement Range | -80°C to +40°C (-112°F to +104°F). |

| Storage Temperature Range | -10°C to +55°C (14°F to +131°F). |
| Rated Temperature Reading Accuracy | With the logger case sitting in an environmental temperature between 0°C and 50°C: Better than ±1°C for -30°C to +20°C. Better than ±1.2°C for -45°C to -30°C and +20°C to +40°C. Better than ±1.7°C for -80°C to -45°C. Actual performance is typically much better than the rated values. Please see the Rated Absolute Accuracy chart below. Accuracy figures can be improved by recalibration. |
| Rated Temperature Reading Resolution | Less than 0.1°C for -80°C to 0°C. Less than 0.2°C for 0°C to +20°C. Less than 0.5°C for +20°C to +40°C. Please see the Rated Native Resolution chart below. LogTag Analyzer® currently displays to one decimal place of °C or °F. The native resolution is what is stored in the LogTag®. |
| Sensor Reaction Time | Typically less than 2 minutes (T90) in moving air (1m/s) for ST10S type. |

| Sampling Interval | Configurable from 1 minute to several hours. |
| Logging Start Options | Push button start or specific date & time. |
| Recording Indication | Flashing ‘OK’ indicator / flashing ‘ALERT’ indicator. |
| Download Time | Typically less than 5 seconds for full memory (8000 readings), depending on computer or readout device used. |
| Environmental | IP61. |
| Power Source | 3V LiMg battery. |
| Battery Life | 2 to 3 years of normal use (based on 15 minute logging, download data monthly. |
| 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). |

To use this LogTag, you will need a USB interface and the LogTag Analyzer software installed on your PC.
This LogTag uses the same Reader as other LogTags, so if you already have one, it will work with these models.
If not, make sure you order one as well. As a bonus, we include the latest free LogTag Analyzer software on USB.
Type S (ST10S)
30mm tip length, ⌀5mm
Type M (ST10M)
65mm tip length, ⌀5mm
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.
Before you can start using a new logger, you will need to configure it with all the settings appropriate to what you are logging.
This is not difficult, and we have instructions on how to do it on this website, but if you would prefer us to do it for you, that service is available at a small cost.
We can pre-configure your LogTag with our recommended settings for:
This means, all you will need to do when you receive your LogTag, is press the Start button and place it in the environment to be monitored.
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.
