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! 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. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B017NF1POE | | Battery Description | 4 x 1.5 V AAA | | Battery description | 4 x 1.5 V AAA | | Brand | Protmex | | Brand Name | Protmex | | Color | Orange | | Colour | Orange | | Customer Reviews | 4.6 out of 5 stars 888 Reviews | | Global Trade Identification Number | 06051651879433 | | Included Components | 4 x AAA Batteries, 1 x Packing Bag, 1 x Use Manual | | Item Dimensions W x H | 6W x 18.4H centimeters | | Item Length | 7.2 Inches | | Item Weight | 190 Grams | | Item weight | 190 Grams | | Manufacturer | PROTMEX | | Model | CECOMINOD046940 | | Mounting Type | Tabletop | | Mounting type | Tabletop | | Number of Items | 1 | | Operating Humidity | 0%-100% | | Part Number | PPM-TI002-3 | | Product dimensions | 6W x 18.4H centimeters | | Temperature Accuracy | 0.5 | | Temperature Reading Accuracy | plus_minus_0_point_5_degrees_celsius | | Unit Count | 1 Count | | Upper Temperature Range | 140 Degrees Fahrenheit | | Voltage | 1.5 Volts | ## Product Details - **Battery description:** 4 x 1.5 V AAA - **Brand:** Protmex - **Colour:** Orange - **Item weight:** 190 Grams - **Product dimensions:** 6W x 18.4H centimeters ## Images ![Protmex PT6508 Temperature Humidity Meter, Digital Thermometer Hygrometer Monitor with Ambient, Dew Point, Wet Bulb for Indoor/Outdoor MIN, MAX, Data Hold, LCD Backlight - Image 1](https://m.media-amazon.com/images/I/61nr4-mCNML.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Impressive Precision and Value – Highly Recommended! *by S***É on 1 November 2024* I recently received the PT6508, and I’m genuinely impressed by its accuracy and performance.

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. ### ⭐⭐⭐⭐⭐ If you want to save hundreds of dollars and want a reliable meter look right here *by S***8 on 28 April 2026* This thing is really a great tool for the price.. as a hvac-r technician having the right tools is crucial when diagnosing a problem especially in ac season. I needed a hygrometer for a job to prove that the reason for all the ric were condensing and spilling out on to the floor was the amount of humidity in the store at that moment.. I don't ever buy cheap tools especially meters. I have Testo guage, probes, multimeter, thermal imaging camera, leak detector, micrometer guage, pyrometer, scale, manometer, and so forth that link to the Testo smart app so I can monitor everything right from my phone.. love it. But seeing as this is the first time I needed one in years I was not wanting to spend $500 bucks on a Testo that will just sit in the van.. after reading reviews and researching hygrometers I decided to give this a try and I'm glad I did. Works perfectly.. proved the dew point was causing the water on the floor and that the coolers were not leaking... professional meter at a toys-r-us price.. ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/317982481-protmex-pt6508-temperature-humidity-meter-digital-thermometer-hygrometer-monitor-ambient](https://www.desertcart.jp/products/317982481-protmex-pt6508-temperature-humidity-meter-digital-thermometer-hygrometer-monitor-ambient) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-21*
