1) Not available as oxygen version.
2) Exclusively suitable for use with dry, gaseous and non-aggressive media. Not possible as flush version.
3) As an oxygen version or oil- and grease-free version, a flush diaphragm model is not available.
4) It is defined by the total measurement uncertainty, which is expressed with the coverage factor (k = 2) and includes the following
factors: the intrinsic performance of the instrument, the measurement uncertainty of the reference instrument, long-term stability,
influence of ambient conditions, drift and temperature effects over the compensated range during a periodic zero point correction.
5) Reference conditions: 15 ... 25 °C (59 ... 77 °F)
