- HIGH: Over 55% RH indicates a humid environment.
3.4. Programmable Alarms
Custom, programmable high and low humidity alarms can be set to notify you when humidity levels fall outside your desired ranges.
3.5. Manual Calibration
The device offers a manual calibration option for both temperature and humidity to ensure professional accuracy of +/- 0.5°F and +/- 2% RH.

4. Understanding Humidity Levels
Maintaining appropriate humidity levels is crucial for comfort and health. Too much humidity can foster biological pollutants like mold, bacteria, viruses, fungi, and dust mites, potentially triggering respiratory ailments. Conversely, insufficient humidity can lead to nosebleeds, skin irritation, breathing difficulties, and static electricity.
5. Maintenance
5.1. Battery Replacement
Replace batteries when the low battery indicator appears on the display. Always use fresh alkaline batteries for optimal performance.
5.2. Cleaning
Clean the unit with a soft, damp cloth. Do not use abrasive cleaners or chemicals that may damage the display or casing.
