The micromanometer-thermometer for air velocity measurement<\/strong> with 200 mbar full scale<\/strong> is a portable instrument designed for measurements with Pitot tubes<\/strong> in HVAC, ventilation, heating, air conditioning and high-velocity airflow control applications.<\/p>\n

Compared to the 20 mbar version, this model is designed for a wider operating range: air velocity measurements from 2\u2026180 m\/s<\/strong> and differential pressures up to \u00b1200 mbar<\/strong>. It is therefore the correct choice when higher air velocities are expected or when the differential pressure generated by the Pitot tube exceeds the range of more sensitive micromanometers.<\/p>\n

The instrument measures the differential pressure<\/strong> detected by the Pitot tube and calculates both air velocity<\/strong> and airflow rate.<\/p>\n

For airflow calculation, the duct cross-sectional area can be entered within the range 0.0001\u20261.9999 m\u00b2<\/strong>. Available measurement units allow operation with pressures in Pa, mbar, mmH\u2082O and PSI<\/strong>, velocities in m\/s, km\/h, ft\/min, mph and knots<\/strong>, airflow in l\/s, m\u00b3\/h and cfm<\/strong>, and temperature in \u00b0C and \u00b0F<\/strong>.<\/p>\n

Temperature measurement is performed using K thermocouple probes<\/strong> in the range -200\u2026+600 \u00b0C<\/strong>. The instrument can also be used as a thermometer with probes fitted with standard miniature connector, or with Pitot tubes equipped with integrated thermocouple when simultaneous air temperature and velocity measurements are required.<\/p>\n

The Max, Min and Avg<\/strong> functions allow the main values to be displayed during inspections, while REL<\/strong> and HOLD<\/strong> support field readings and comparisons. The IP66<\/strong> protection rating makes the instrument suitable for technical environments and maintenance operations on systems and installations.<\/p>\n

It is the correct choice when a portable instrument for immediate high-velocity measurements is required, without the need for internal data logging.<\/p>\n

    FAQ – Micromanometer-thermometer<\/h2>\n

    When should the 200 mbar full-scale model be selected?<\/strong>
    \nIt is recommended when air velocities up to 180 m\/s or higher differential pressures must be measured compared to the range covered by the 20 mbar model. It is suitable for stronger airflow conditions and inspections on higher-velocity systems.<\/p>\n

    What is the difference between the 20 mbar and 200 mbar models?<\/strong>
    \nThe 20 mbar model measures air velocities from 2 to 55 m\/s and is more suitable for low differential pressures. The 200 mbar model reaches up to 180 m\/s and is designed for applications with higher velocities and differential pressures.<\/p>\n

    How is airflow rate determined?<\/strong>
    \nThe instrument calculates velocity from the differential pressure measured with the Pitot tube. By entering the duct cross-sectional area, it can also calculate airflow rate.<\/p>\n

    Which measurement units are available?<\/strong>
    \nUnits are available for differential pressure, velocity, airflow and temperature. These include: Pa, mbar, mmH\u2082O, PSI, m\/s, km\/h, ft\/min, mph, knots, l\/s, m\u00b3\/h, cfm, \u00b0C and \u00b0F.<\/p>\n

    Is air temperature compensated?<\/strong>
    \nYes, the instrument provides automatic or manual air temperature compensation within the range -200\u2026+600 \u00b0C.<\/p>\n

    Can it also measure temperature only?<\/strong>
    \nYes, it can be used as a thermometer with K thermocouple probes fitted with standard miniature connector.<\/p>\n

    Must Pitot tubes be ordered separately?<\/strong>
    \nYes, Pitot tubes, PW cable and K thermocouple probes must be ordered separately. Selection depends on the duct type, required tube length and whether integrated temperature measurement inside the tube is needed.<\/p>\n","protected":false},"excerpt":{"rendered":"
