feature

InAccuracy within 1.5% within the pressure range of 15 to 115 kPa

Long term instability is continuously measured indoors and under natural conditions, with an annual value below0.5 %

Within a wide temperature range（-The influence of temperature on the signal is less than 1%, ranging from 20 to 50 degrees Celsius
