Protmex PT6508 Temperature Humidity Meter, Digital Thermometer Hygrometer Monitor with Ambient, Dew Point, Wet Bulb for Indoor/Outdoor MIN, MAX, Data Hold, LCD Backlight

Q: Can the relative humidity be calibrated by the user?

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?

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?

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?

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.

Handy little tool!

This is a brilliant little tool for identifying relative humidity within the property and calculating the dew point. It’s an added bonus that it provides the wet bulb reading! I have purchased a few of these and this one was the cheapest and works the best! It’s also a sturdy little device.

Great value for the price paid

Great value for the price paid and does what it needs to do with readings similar to a more expensive 'branded' tool
