Instalation
| The SK-500B is an indoor use desk-top type digital barometer. Install the unit vertically avoiding the places as below. ▪In flammable gases, corrosive gases and explasive gases ▪In a place subject to direct sunshine and near the thermal appliance ▪Near the exhaust port of airconditioner ▪In a plece subject to vibration ▪Beyond the operation ambient (-10 to 50°C,less than 85%rh, no condensing) ▪In an environment where electrical noise is generated ▪In a place subject to rain and splash water |
Caution In Use
Atmospheric pressure differs according to the height.
This SK-500B is high sensitive device. For accurate measurement, careully align the reference revel on the unit with
the pressure to be measured. The reference level is in the center of the pressure port on rear of the case.

TRIVIAL
Atmospheric pressure is defined as “power” on the horizontal surface by weight of the air and hectopascal (hPa) is used
as a unit of atmospheric pressure.
The air becomes atmospheric layer and wraps up the earth. The weight (pressure) of approx. 1kg per 1cm2 applies to sea level
and it is equivalent to approx. 1,013 hPa.
As altitude rises, the air decreases and its weight decrease.This means that the atmospheric pressure falls down as altitude rises.
Upon reaching a height of 100m above sea level, the atmospheric pressure will drop approx. 12 hPa.
Thus, in order to compare the readings measured at different spots (heights), it is necessary to convert it into the same altitude
as mean sea level. The converted atmospheric pressure is called Sea level pressure.
