Review: Pro quality hygrometer - Took a chance on this not well-known brand. I've been using this in my HVAC career. It is accurate and very easy to use.

## Questions & Answers

**Q: Can the relative humidity be calibrated by the user?**
A: Neither relative humidity nor temperature can be calibrated by the user. User's manual does not mention this possibility.

**Q: Can this item be sent in for re-calibration periodically, and updated certificate?**
A: All the items have been calibrated before sending out, and if you need to calibate again, then you can send it to us for re-calibration, but it will cost a lot of time and shipping fee

**Q: ?Viene con el certificado de calibración?**
A: Thank you for your question. If you need it you can contact our customer service and we will send you a calibration operation manual, which is recommended to be used under professional personnel and operating equipment.

**Q: Has anyone who bought this unit tested it for accuracy?**
A: That I do not know. what I can say is that the temperature it shows is close to what the weather people say the temp.s are. I bought it because the local weather people have decided to no longer give the dew points in the forecast. I do know that the higher the dew point reading the device shows the more humid it feels. I also had issue with deciding to just give a date on the map as to when the "Monsoon season" starts and stops. The method of a dew point higher than 55degrees 3 days in a row for the start and below 55 degrees 3 days in a row for the end makes more sense.

### ⭐⭐⭐⭐⭐ Good quality, easy to use.
*by K***M on January 2, 2026*

Great hygrometer. Good quality, use for work and think it will last for awhile, with proper care. Easy to use, and easy to read. Can't speak on battery life yet. I didn't have anything to calibrate and/or compare to, so don't know how "precise" it is either, but provided data within a range that "seemed" correct, even if off a percent or so.
