eslog sensors
Choose the measurement accuracy and range that fit the product you transport or store.
Compare sensors
eslog sensors record conditions while a product is transported and stored.
Depending on the version, you can monitor temperature or temperature and humidity, then analyse the measurement history in the eslog system.
Instead of relying on a single reading taken in a warehouse or vehicle, you receive a data history connected to a specific sensor and process.
Select a sensor based on accuracy, temperature range and whether humidity data is also required.

−40 to +85 °C
Temperature range

When higher accuracy and a wider range matter.
−40 to +125 °C
Temperature range

When humidity matters alongside temperature.

Hold your phone to the sensor and the data appears in the app straight away. No computer, no USB cable, no printer.
The sensor records conditions throughout transport and storage, so you see the product's complete history rather than one moment in time.
Once read, the data goes to the eslog_ panel. There you get a chart of conditions for each batch, a view of the route, alerts, and a report you can generate on demand.
eslog_ fits in the palm of your hand and measures temperature to within ±0.2 °C across a range from −40 to +125 °C. The Humidity version also records humidity to within ±1.8 %rH. Each sensor holds up to 1,760 readings.
eslog holds an EU Declaration of Conformity and carries the CE mark, confirming it meets EU requirements for radio equipment. The NFC module complies with EN 300 330, and the device as a whole meets requirements for electromagnetic compatibility, safety and restricted hazardous substances. You can deploy it anywhere in the EU.

We develop and manufacture the sensor, the app and the panel in Poland. You deal directly with the people who know the device inside out, and you can adapt it to your process: add a probe, change the housing, or extend the panel with features built around your data.

eslog custom
We can adapt eslog to your product and process.
If a standard sensor does not fully meet your needs, we can extend both the hardware and software. This may mean an additional measuring element, a change to the device construction, or a panel feature created specifically to analyse data from your process.
We can extend the eslog hardware with elements needed for a specific application, such as an additional probe or another measuring element.
+ additional measuring probe
We can extend the eslog panel with functions tailored to a specific process, including dedicated data analysis, presentation and business logic.
Do not adapt the process to the tool. Let us adapt eslog to the process.

The pilot is free, and the devices stay with you. You test; we help you understand the data.
