FAQ
Can it measure two temperatures at once?
Yes. It reads the built-in sensor and the external probe at the same time, so you can check, for example, the room and the inside of a cooler together.
How do I get reports?
Connect it to a computer by USB to get PDF and CSV reports, or view the data in the Bluetooth app.
Is it waterproof?
No. It's rated IP20 for indoor use. Keep the logger body dry and place only the probe in wet or cold areas.
