Full Product Description
The amiciSense AS-55 digital thermometer and hygrometer shows indoor temperature, relative humidity, time and date on one LCD. Put it on a bedroom shelf, office desk or storage-room wall to see the conditions where the monitor sits.
Check the MAX and MIN figures to see how the room changed overnight or while you were away. The monitor keeps separate 24-hour and all-time records for both temperature and humidity. Its colour bar marks humidity below 30% as LOW, 30–69% as GOOD and 70% or above as HIGH.
- Measurement range — −20 to 85 °C (−4 to 185 °F) and 5–95% relative humidity. Readings refresh about every 10 seconds.
- Night-time reading — tap the front touch button to light the LCD for 15 seconds. A rear button switches between °C and °F.
- Placement — open the fold-out stand or use the rear hanging hook. Keep the side vents clear and give the readings a few minutes to settle after moving the monitor.
