In addition to all connectable probes Swema 3000mdH+ also has two built-in sensors, one differential pressure sensor (manometer) and one barometer, and it has also a thermocouple connector for connecting external temperature sensor typ K(a 1 m wire probe type K is included).
Swema 3000mdH+ is the same model as Swema 3000md, but with an extensive range for the built-in differential pressure sensor, ±10.000Pa.

Unique measuring methods
For all external sensor and the built-in manometer there is a wide array of methods for measuring. For example Comfort (CO) for the draught sensor, Backpressure (BP) for SwemaFlow 125 and Logging (LOG) for all sensors.

(m) for manometer -10 000...10 000Pa
With the integrated manometer together with a pitot static pipe Swema 3000mdH+ will measure air velocity and air flow in a ventilation duct (according to EN 16211 method ID 1, ID 3, ST 1, ET 1).

When you enter the k-factor with a ventilation sensor connected the display will immediately show the airflow. The instrument has a built-in valve so the zero reference is checked everytime you perform a measurement.
With this feature your measurement will be correct and no need to disconnect anything!
It is possible to deactivate the automatic zero reference checking for slightly faster measuring.

The differential pressure sensor in Swema 3000mdH+ has a high range with little trade off in uncertainty.
Selectable to a 0.01Pa precision.

(d) for density compensation
Thanks to the barometer and thermo element the air pressure and temperature can always be measured. The air flow and air velocity measure is therefore automatically compensated for actual air density. All for the best accuracy!

If you connect a sensor with an integrated temperature sensor this is automatically used for density compensation. If temperature measuring is not a feature of the connected sensor, for example in differential pressure sensor Swa 10, Swa 07 and SwemaFlow 65, it is possible to connect such a measuring sensor to the thermo element connector of Swema 3000mdH+ or manually entering a temperature value.

Since Swema 3000mdH+ contains a barometer and differential pressure sensor it is recommended to calibrate every year. External sensors are indivually calibrated and need not be calibrated together with Swema 3000mdH+.

The calibration protocol is saved in the instrument and and sensors and you can at any time transfer it to PC or mini printer to show it.

Measuring range:
Differential pressure: -10.000…10.000Pa (Integrated manometer)
Resolution: 0,1 or 1 Pa (selectable)
Air velocity: approx. 2...129m/s, 390…9999fpm (calculated)
Barometer: 600...1200 hPa (integrated)
Temperature: -270...1372 °C, -450...2500 °F (standard curve, Thermo couple connector type K)
Thread sensor:-40...400°C, -40...750 °F (inluded, class 1, thermo couple type K)

Measurement uncertainty at 23°C ±5°C:
Differential pressure: ±1% read value, minimum ±0,4 Pa (after zeroing)
Barometer: ±2,5 hPa
Temperature: ±0,3°C at -10...70°C, with included thermo couple ±2,5°C

Uncertainty according to GUM (JCGM 100ː2008) using a coverage factor of 2, which for a normal distribution corresponds to a probability of 95%. It is important to correct the measurement values with the corrections stated in the calibration certificate to obtain the above uncertainties.
