## Long description

The Greenblue 46004 Black is a battery-powered hygrometer and thermometer designed for combined indoor and outdoor monitoring. It displays current temperature and relative humidity values and includes a barometer-based trend indicator to show recent changes. The unit supports both °C and °F temperature units, features an integrated clock and alarm functions, and is finished in a black housing suitable for home or sheltered outdoor placement.
Advantages
The device provides separate measuring ranges for indoor and outdoor temperatures and a broad humidity measuring span for outdoor conditions. Battery operation allows flexible placement without wiring, while the built-in display offers clear, immediate readings. The barometric trend display helps track shifts in weather conditions, and the selectable temperature units suit different user preferences.
Suitable for
 Home rooms where monitoring humidity and temperature is important (living room, nursery, basement)
 Protected outdoor locations such as porches, balconies or garages
 Hobby greenhouses and plant-monitoring where relative humidity and temperature control are required
 Everyday household use with alarm and clock functions for time-sensitive monitoring
Key specifications
 Indoor temperature measurement range: 0 to 50 °C
 Outdoor temperature measurement range: -20 to 60 °C
 Outdoor relative humidity measurement range: 20% to 95% RH
 Temperature units: Celsius (°C) and Fahrenheit (°F)
 Integrated clock and alarm functions
 Battery-powered operation (compatible with standard AA/AAA battery sizes)
 Built-in display and black housing
How to use
Insert the recommended batteries and place the main unit indoors on a stable surface or mount it on a wall at eye level for convenient reading. Position any remote outdoor probe or the outdoor-sensing part in a sheltered location away from direct sunlight and heavy precipitation to ensure accurate readings. Use the unit controls to switch temperature units between °C and °F if needed, set the clock and program the alarm. Consult the product manual for details on synchronising any external sensors and for instructions on replacing batteries.
Usage recommendations
To maintain measurement accuracy, avoid placing the device near heat sources, air vents or in direct sunlight. For outdoor readings, locate the sensor in a shaded, well-ventilated spot sheltered from rain. Replace batteries promptly when low to prevent data loss, and periodically check the display and sensor mounting for secure placement.
