FIELD: physics, measurement.
SUBSTANCE: invention is applied for measurement of barometric pressure, temperature or humidity. The tool mechanism includes set of elements, including pressure transducer sensing barometric pressure and transforming it to electric signals, step motor with clock shaft used in mechanism of common quartz clock, microprocessor and battery on-line interconnected so that microprocessor controls motion of step motor with battery-generated energy as a response to atmospheric pressure versions sensed by pressure transducer; and the case containing this set of elements with motor shaft stretched outside from the case. Other transducers such as temperature or humidity converters can alternatively be used.
EFFECT: higher accuracy as well as simplification of use, installation and calibration.
