Hazel Lee baby indoor hygrometer household thermometer hygrometer table precision battery-free precision 'blue'
Thermometer for the mechanical thermometer placed in an environment within a few minutes after the automatic sensor will not need to adjust the battery-free environmentally friendly and durable
(10 million to receive the goods to open sealed packaging, air-sealed packaging, the value will be some differences, and then placed 1-2 hours indoors can be normal measurement of temperature and humidity!)
The use of thermometer errors (thermometer can not display the air-conditioning temperature as a reference because the display shows the temperature of the outlet when the heating / cooling air to the room when the temperature is not so high / low also affected by the outdoor)
Brand: GEMlead / Hazel
Model: TH101B indoor temperature hygrometer (blue box)
Size: diameter 12.9CM * thickness of 2.8CM
Weight: 0.2KG / a
The Relationship Between Daily Life and Temperature and Humidity
When the indoor environment:
Temperature 18 to 25 degrees Celsius, relative humidity of 40 to 70%, the human body feel comfortable
Temperature of 24 to 30 degrees Celsius, relatively less than 60%, the human body feel hot and not boring
Temperature higher than 30 degrees Celsius, humidity greater than 70%, the body feels hot
Temperature is higher than 36 degrees Celsius, humidity greater than 80%, the body feels hot unbearable, sweating mechanism blocked, easy heat stroke.
Scope of application:
Can be widely used to measure the room, office, workshop, laboratories, schools, shopping malls, warehouses and other environmental temperature and humidity.
Temperature range: -30 degrees Celsius to 50 degrees Celsius
Temperature error: plus or minus 1 degree Celsius (error range is 2 degrees Celsius)
Humidity error: plus or minus 5% (error range is within 10%)
Under normal circumstances, the same temperature, humidity deviation is normal , You buy a hundred thermometers and certainly there are several differences in temperature and humidity, the bumpy road back and forth with your local temperature and humidity differences, I believe we can understand the receipt of the goods when a little beat by hand, or with a small Bowl of hot water smoked will adjust back to normal.
1, the new need to adjust the temperature and humidity to buy it?
* This product is strictly adjusted at the factory are accurate, under normal circumstances do not need to adjust to normal use, but there may be due to transport vibration reasons, so that readings deviation, if the display readings are in doubt, Value within the scope of the error is greater than the technical indicators, can be observed in the absence of small environmental control reference (about 30 minutes later, the more accurate the longer), confirmed after adjustment.
2, how to adjust the hygrometer (table)?
3, how to adjust the thermometer (table)?
4, the use of temperature hygrometer process should pay attention to what things?
* The hygrometer should be mounted in a well-ventilated place to avoid hanging in the direct sunlight on the wall, air-conditioning outlet and other places.
5, pointer-type hygrometer temperature measurement principle?
Pointer thermometer is the use of two different metal temperature changes in the expansion of the principle of different work.The main component is a two or more pieces of metal laminated together laminated metal pieces.In order to improve the sensitivity of temperature measurement , The metal sheet is usually formed into a spiral coil shape.When the temperature of the multi-layer metal sheet is changed, the expansion or contraction of the metal layers is not equal so that the spiral coil is rolled up or loosened.As one end of the spiral coil is fixed, A freely rotatable pointer is connected so that when the bimetal senses a temperature change, the pointer can indicate the temperature on a circular graduation scale.
