1) Process connection and O-ring depending on the selected pressure measuring range.
2) For pressure measuring ranges 0 ... 25 mbar, 0 ... 40 mbar and 0 ... 60 mbar [0 ... 0.4 psi, 0 ... 0.6 psi and 0 ... 0.9 psi] all wetted
parts are made of stainless steel, silicon, aluminium, gold, silicone.
3) 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 adjustment.
4) Reference conditions: 15 ... 25 °C [59 ... 77 °F]
5) For pressure measuring ranges of 0 ... 25 mbar, 0 ... 40 mbar and 0 ... 60 mbar [0 ... 0.4 psi, 0 ... 0.6 psi and 0 ... 0.9 psi], the
medium temperature and storage temperature are limited to 80 °C [176 °F].
