Description

The main advantages of RM YOUNG digital barometers are performance, miniaturization and simplicity. In their tight case, these totally customizable instruments allow a reliable measure of the atmospheric pressure. Among the available options, we can quote the calculation of QFE and QNH pressures, or adjustment of measure range.

* Defined as +/- 1 standard deviation from NIST traceable pressure reference. Includes non-linearity,  hysteresis, repeatability, and calibration uncertainty.

** Defined as +/- 1 standard deviation from ideal analog output. Total analog output accuracy is the root   sum square of digital accuracy, analog accuracy, and analog temperature dependence.
