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 ### ⭐⭐⭐⭐⭐ Review *by J***N on April 8, 2026* ### ⭐⭐⭐⭐⭐ Review *by L***E on April 9, 2026* ### ⭐⭐⭐⭐⭐ Review *by K***H on October 20, 2025* ## Frequently Bought Together - Protmex PT6508 Temperature Humidity Meter, Digital Thermometer Hygrometer Monitor with Ambient, Dew Point, Wet Bulb for Indoor/Outdoor MIN, MAX, Data Hold, LCD Backlight - General Tools MMD4E Digital Moisture Meter, Water Leak Detector, Moisture Tester, Pin Type, Backlit LCD Display With Audible and Visual High-Medium-Low Moisture Content Alerts, Grays - Klein Tools ET140 Pinless Moisture Meter for Non-Destructive Moisture Detection in Drywall, Wood, and Masonry; Detects up to 3/4-Inch Below Surface --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/23678036-pt6508-temperature-humidity-meter-digital-thermometer-hygrometer-monitor-with-ambient](https://www.desertcart.vu/products/23678036-pt6508-temperature-humidity-meter-digital-thermometer-hygrometer-monitor-with-ambient) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
