o Scale ranges for pressure values between 60  mbar and 2,5 bar abs:

- see table B1 at page P06; (divisions as per table C1 at page P04);

- other graduations not normalized for single or double range (on request).

o Unit of pressure:

- mbar, bar, kPa, kg/cm2 and psi for single or double range.

o Scale angle:

- 270 ° (180 ° for range 0÷60 mbar).

• Pointer

- aluminium with micrometer adjustment.

• Dial

- white aluminium with black figures (for dial modifications see available options).

• Accuracy (according to EN 837)

- class 1,6 (± 1,6% of full scale deflection).

note 1: accuracy class is not affected by atmosphericpressure changes.

note 2: accuracy indicated on the pressure gauge does not consider the interference of on eventually applied electric contact.

• Ambient temperature

- -20÷+60°C.

• Operating temperature

- max 120°C.

• Thermal drift

out of the optimum ambient temperature values included within +15 ÷ +25°C, the thermal drift affects the instruments accuracy as follows:

- 0,3% every 10°C for model MA 325;

- 0,5% every 10°C for model MA 425.
