Questions buyers ask
Can I get a PDF temperature report without a computer?
Yes. Download the stored measurements using the DSHT mobile app, then generate a PDF report on your phone.

DSHT records locally and uses a nearby Bluetooth connection for retrieval. It is not a cellular or Wi-Fi cloud gateway.
Can I use it for refrigerated transport and retail freezers?
These are target applications. Share your temperature range, journey duration, accuracy needs and qualification criteria so we can check the suitable configuration.
Can the app and reports carry our own brand?
Yes. OEM projects can include device branding, app customization and branded PDF reports. Send your brand assets, required languages and report fields to discuss scope.
