Extech RHT510 Hygro-Thermometer Psychrometer

The Extech RHT510 Hygro-Thermometer Psychrometer is a versatile device designed to measure temperature, relative humidity, wet bulb, and dew point. It features a backlit LCD for easy viewing in low-light conditions and includes functions such as data hold, minimum/maximum readings, and auto power off options. User feedback reveals mixed sentiments about the product. While some users appreciate its accuracy, stating, "this was the fix! Found it just fine, and temp readings are accurate!", others criticize it for being inferior to digital thermometers. The recurring theme among dissatisfied users is the perceived inaccuracy of humidity readings, with one user noting, "Humidity very inaccurate; I have 6 sensors and all of them are more than 10% lower in RH readings." Given the varied consumer opinions, the Extech RHT510 may not be the best choice for those seeking highly accurate readings, especially in comparison to digital options. Potential buyers should weigh the pros and cons before making a decision, particularly if precise measurements are crucial for their needs.
