Features

• Compact Design: Measuring approximately 7 x 7 x 1.3 cm, this unit is small yet features a large, easy-to-read LCD display for clear visibility from a distance. Note: This product is not waterproof.
• Comfort Level Indicator: The display shows comfort levels in three stages: DRY (humidity below 30%), COMFORT (humidity between 30% and 69%), and WET (humidity 70% or above).
• High-Precision Sensor: Equipped with a high-accuracy sensor, the device provides reliable temperature readings with an error margin of ±1°C (between 0°C and 40°C) and ±2°C (between 40°C and 60°C). Humidity readings have an error margin of ±3-5%RH. Data updates every 10 seconds for responsive monitoring.
• Versatile Placement Options: The thermometer hygrometer can be placed in three ways: using its strong built-in magnet for metal surfaces (like refrigerators), mounted on a wall, or using its integrated tabletop stand. This allows for flexible placement in various indoor environments such as kitchens, bedrooms, offices, and more.
• Household Comfort Management: Easily monitor indoor air conditions to create a comfortable environment for family members, including babies, and pets (dogs, cats, rabbits, reptiles). Understanding humidity levels helps in timely adjustment of humidifiers or dehumidifiers.
