Applications
- Medicine storage rooms: under Rules No. 260n humidity must not exceed 65 % unless the manufacturer states otherwise — Smartag RHT records both temperature and humidity.
- Temperature and humidity mapping when the protocol sets humidity criteria.
- Pharmacies and storerooms instead of a separate thermometer and hygrometer.
- Transport of humidity-sensitive cargo.

How to use
- Set up
Connect the device to a computer and set the logging interval, thresholds and delayed start in the software.
- Start
Press Start or wait for the delayed start — the LEDs confirm that logging is on.
- Logging
The device records values at the set interval; the LEDs show whether a threshold was exceeded.
- Report
Connect to USB and save the report and data; record the serial number in the log.
- Next cycle
Clear the memory and start again — the device is reusable. Keep track of the verification date.
Modifications with humidity have a 1-year verification interval (Smartag T has 2 years). Plan verification in advance so the device does not drop out of a mapping study.
Frequently asked questions
Is Smartag RHT reusable?
Yes. After a cycle the data is saved, the memory is cleared and the device is started again.
What is the humidity accuracy?
±5 % in the 5–95 % range. Temperature: ±0.5 °C from −30 to +40 °C.
How often is Smartag RHT verified?
Every year, like all Smartag modifications that measure humidity.
