The user-friendly large-screen design allows you to quickly and easy viewing readings on the large 2.26-inch screen. HIGH ACCURACY SENSOR With a built-in Switzerland high precision temperature and humidity sensor for measuring temperature, humidity, wet bulb, and dew point, without complicated instructions, extremely simple to use. ABS PROTECTIVE CAP The ABS Protective cap can protect the probe head from external damage, greatly prolongs the service life, and reduces the number of replacements. POWER SAVING Automatic power off after 30 minutes when there is no operation, better power saving, and has a low battery alert function, a timely reminder that it is time to replace the battery. FAQ Q: How do I use this psychrometer to get a wet bulb? A: You just push the DP/WB button and it cycles through temperature, relative humidity (RH), dew point, and wet bulb temperature, all in Fahrenheit and Celsius. You don't have to get it or anything to get the wet-bulb temperature: at the end of the probe is a temperature/humidity sensor, so it measures both and calculates the wet bulb. Q: Can I recalibrate the hygrometer? A: Protmex hygrometer thermometer has been calibrated correctly before leaving the factory. If you want to calibrate it, we will provide you with a calibration guide. We suggest professional engineers calibrate the digital temperature humidity meter. Q: How long does the humidity meter take to give an accurate reading when changing environments? A: It takes constant readings in real time and is subject to variations at the point of the reading (the tip). Readings are almost instantaneous. To obtain accurate measurement data, it takes 10 minutes in a stable environment, and the sampling rate is 1 time in 3 seconds. Q: Is there any way to have the backlight stay on constantly? A: Yes, it is possible to achieve the backlight function that is always on. Press the backlight button and hold it for more than 2 seconds to enable or disable the backlight function. Q: What type of battery does the hygrometer indoor humidity use? A: 1.5V AAA battery. We'll throw in three batteries. Protmex HT607 humidity range: 0.0% ~99.9%RH Accuracy: 20%~ 80%: ±3.0%RH; others: ±4.0%RH Resolution: 0.1 Q: Does it come with a case or a protected cap? A: Yes, it comes with a soft storage bag and a protected cap, which better protects the probe head from external damage, and a longer life span. Technical Specifications Review: Good Device But With Some Logic Issues - This is a well made instrument, quality construction. I have compared its F Temp readings to a NIST bulb thermo I have and it within 1 degree, so accuracy is very good. However there are two issues. One is that it has a lot of measuring delay due to thermal lag of the heating and cooling of the sensor, so you need to let it stabilize in the environment you want to measure for at lest 3 minutes. The other issue is that it will not show the MAX / MIN at the same time as it displays the current temp. This is a severe issue, and for me it is really a deal killer. If you enable its MAX/MIN function its behavior is that it resets the previous MAX/MIN. After setting its state to record MAX/MIN, there is no way to have it read and report to you the current Temp. After the MAX/MIN state of the device is enabled all you can read out is those two measurements of what it has been recording as the MAX/MIN, This is a severe issue, as if you want to ask it for the current F you must disable its MAX/MIN state and return to its current reading state, which them resets the MAX/MIN it has been recoding. SO the previous MAX/MIN data is then lost. The device should be able to record MAX/MIN as it also reports the current Temp readings. I have a device by another manufacturer (ThermoPro TP357) that does this and also recodred a history log of the MAX/MIN. It is a far more useful device with much better programming logic. I do still use the PROTmex as its very large easy to read screen and it accuracy make it well suited to making current reading in a fixed location over period of time. It is a good, well made device, and I can recommend it, but please realize its failure to report and record MAX/MIN at the same time. as it shows the current temperature is a severe issue, You get one state or the other, but not both ! Review: Excellent and not expensive - I got the Protmex HT607 because I had several little hygrometers from various manufacturers placed around the house and they did not agree with each other, or with the hygrometers clipped to my guitars' strings. After using the Protmex HT607, I got rid of the smallest, least accurate hygrometers. The Protmex HT607 shows humidity and temperature instantly. It is so sensitive that the tenths vary constantly as it samples the air. The probe is protected against damage and dust by a snap-on cover, at little hard to take off. The plastic case is strong, and comes with a velvet carrying pouch. ## Features - 【HIGH-PRECISION DIGITAL HYGROMETER】 High-precision digital temperature and humidity meter, top-notch probe sensor.

HT607 psychrometer meter has 2 temperature units, ℉, and ℃, which can be adjusted according to your needs. **Q: How accurate is this device?** A: It’s accurate. Double checked with the temperature readings on the WeatherApp. **Q: Does it use bateries or is rechargable?** A: Thank you for your question. Our HT607 humidity meter and temperture use the bateries, the bateries need use 3*AAA. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good Device But With Some Logic Issues *by C***D on June 28, 2025* This is a well made instrument, quality construction.
