Extech Hygrometers Editorial Review

The EXTECH RH490 HYGRO-Thermometer has garnered mixed reviews from users, particularly those in professional settings. On one hand, many technicians Consider it to be the best on the market, praising its dual display and specific features like dew point, wet bulb readings, and grains per pound (GPP) metrics, which are particularly useful in their daily operations. Users appreciate the precision of the readings, claiming an accuracy of 2% for relative humidity and highlighting its dependable performance. However, durability is a significant concern among users, particularly those in demanding industries like water remediation. A critical point raised is the fragility of the sensor chip located at the top; users reported that the small copper connectors that secure the sensor can easily break, leading to malfunctioning devices. This has resulted in customers having multiple unusable meters that require expensive repairs, with some expressing frustration over the lack of accessibility to replacement parts and the high cost of professional servicing. In summary, the EXTECH RH490 is celebrated for its performance and precision in readings but is criticized for its lack of durability and high repair costs, leading to a divided reception among users. **
