Ambient Temperature and Relative Humidity Ref Review: 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. Review: 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 ## 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.

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 calibraciΓ³n?** 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Handy little tool! *by S***. on 21 May 2025* This is a brilliant little tool for identifying relative humidity within the property and calculating the dew point.
