Extech RH101 Combination Humidity Meter and Infrared Thermometer

**Editorial Review of the Extech RH101 Combination Humidity Meter and Infrared Thermometer** The Extech RH101 has garnered a mixed reception amongst users, particularly within the Heating & Air Conditioning field. While it serves its intended purpose reasonably well, many customers have experienced issues with the accuracy of its readings, especially at higher temperatures and humidity levels. Some users noted that the infrared readings could be off by approximately 10°F, while air temperature readings could vary by about 5°F. This variability raises some concerns regarding the overall reliability that professionals in the field might expect. Despite these accuracy issues, some engineers have pointed out that the Extech RH101 performs comparably to much more expensive RH meter alternatives, albeit with similar flaws in precision. However, reviews also indicate a significant downside concerning the durability of the device, particularly around its wiring. Users have reported that the wire connections to the probe are weak, leading to failures and difficulties when seeking replacements. In some cases, the device worked only for a short period before malfunctioning, necessitating replacements which did not guarantee improved performance. Overall, the Extech RH101 presents a cost-effective option for those needing basic humidity and temperature readings, but potential buyers should be aware of its limitations regarding accuracy and durability. **
