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.
