Applications/Examples of results
This is a barometer/altimeter equipped with correction functions, developed with a focus on the essential functions in measurement technology and featuring high-quality sensors. It can perform high-resolution measurements of atmospheric pressure with an accuracy of 0.1 hPa and altitude with an accuracy of 0.1 m, demonstrating excellent performance in terms of precision and response speed. Additionally, it can display the trend of measured values from the start of measurement and can also be used as a variometer (altitude meter). The three-stage LCD display with a backlight provides ease of use and wide visibility regardless of day or night, while the power-saving design and configurable auto power-off function ensure the long life of the two AA batteries that power it. It is suitable for various atmospheric pressure measurement applications, such as control for internal combustion engines in vehicles, navigation systems, and meteorological observation stations. An optional ISO calibration certificate can also be included, allowing it to be used as a reference instrument to verify the accuracy of other devices.
