Description
Thermometer-hygrometer National Geographic 4 Measurement Results Black (9070200) displays the time, day of the week, temperature, humidity inside and outside the room, comfort level in the form of a pictogram. The model allows you to program sound signals for temperature and humidity, when going beyond which the device alerts the user with a sound signal. Modern laconic design and the widest range of functions will allow you to use the thermometer-hygrometer with equal success both in an apartment, office and in a private house.
Functional features:
- Measuring temperature and humidity inside and outside the premises.
- Display the trend of change of external and internal temperature
- Recording maximum and minimum values of temperature and humidity.
- Sound signal when temperature and humidity go beyond the set limits inside and outside the premises
- Possibility of connecting up to 3 external temperature and humidity sensors (supplied in the kit)
- Comfort level
Indoor air temperature:
- Units of measurement: ºС or ºF
- Measurement range: -9.9°C - 60°C (-14°F - 140°F)
- Measurement accuracy: +/- 1°C or +/- 2°F
- Fixing Min/Max temperature values
Outside air temperature:
- Units of measurement: ºС or ºF
- Measuring range: -50°C - 60°C (-58°F - 140°F)
- Measurement accuracy: +/- 1°C or +/- 2°F
- Fixing Min/Max temperature values
Indoor air humidity:
- Units of measurement: % RH
- Measurement range: 20% to 95%
- Measurement resolution: 1%
- Measurement accuracy: +/-5%
- Fixing Min/Max values of relative humidity
Air humidity outside the room:
- Units of measurement: % RH
- Measurement range: 20% to 95%
- Measurement resolution: 1%
- Measurement accuracy: +/-5%
- Fixing Min/Max values of relative humidity
Transferring data from an external sensor:
- Information on your station is updated every 4-8 seconds.
- Transmission distance increased to 30 meters (in open areas).
- Radio signal transmission frequency 433MHz
- Possibility of connecting up to 3 external temperature and humidity sensors (supplied in the kit)
Indoor comfort level:
- A complex indicator that measures the ratio of temperature and humidity and displays the overall comfort level in the room in the form of symbols: "sad" face (humid), "neutral" face (dry), "happy" face (comfortable). Dry: indoor humidity level from 20% to 40%; Comfortable: indoor humidity level between 55% and 65%; Humid: indoor humidity level between 66% and 95%.
- During the period when central or stove heating is on, the air in the rooms is greatly dried out, and the air humidity can drop to 20%. Dry air has a very negative effect on the general condition of a person, leads more quickly to fatigue, drowsiness, to an exacerbation of allergies and diseases of the upper respiratory tract, to a decrease in immunity. The number of positive ions increases in a dry atmosphere, and affects both the physical and mental state of people. The mucous membrane of the nose and throat dries out, resistance to viruses and infections decreases, which increases the likelihood of developing acute respiratory infections.
