is also intended to measure atmosphere pressure in the (720..780) mm of mercury
in various practical works.

Precision of measurement, ±3 millimeters of mercury at the (730..770) mm range
and ±5 millimeters of mercury at the other ranges.

The barometer is mounted inside a plastic box of 135 mm diameter. The device is
protected by flat glass plate at the front side. The case has a hook to hang the device at.
