Review: Testato, funziona benissimo, nella descrizione ci sono scritte le funzioni. Lo consiglio
Review: I recently received the PT6508, and I’m genuinely impressed by its accuracy and performance. Upon testing, I discovered that the temperature and humidity readings are powered by the SHT35 sensor from Sensirion, a top-quality chip known for its high precision. In fact, it’s more accurate than what’s listed on the box, which was a pleasant surprise! The device works perfectly for my needs and consistently delivers reliable readings. For anyone looking for a precise, no-nonsense temperature and humidity meter, the PT6508 is an excellent choice. It absolutely fulfills its purpose, and I couldn’t ask for more!

## Features

- PT6508 psychrometer HVAC is a new type of digital temperature and humidity meter, which is designed to combine the functions of a humidity meter, temperature meter, wet bulb temperature, and dew point temperature. And dew point is a measure of how much water vapor is actually in the air.
- Dual display humidity and temperature with accurate measuring: Humidity range: 0% - 100%RH. Temperature range: -20℃(-4℉) - 60℃(140℉). Dew point Temperature :-50℃(-58℉) - 60℃(140℉). Wet Bulb Temperature:-20℃(-4℉) - 60℃(140℉).
- Digital psychrometers are used for a high range of applications HVAC, including industry, agriculture, meteorology, medicine, daily life, building engineering, paranormal investigator, the wine cellar, machine room, and data storeroom.
- Multiple functions: With data retention, data storage, unit conversion, backlight, low battery indicator, automatic shutdown, and maximum and minimum functions.
- LCD display with backlight with high accuracy sensor, LCD brighter in the darker places. Auto shutdown without operation after 30 minutes.

## 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.

*by K***H on 20 October 2025*

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. I can honestly say it's the best hygrometer I've tried yet. It has regular dry bulb and relative humidity readings.. It also has dew point and wet bulb temperature readings. And many other features also. For the he price, this one is a winner
