SwemaMan 8 is an accurate and low position dependent differential pressure instrument with a built in zero-valve for automatic zero pressure check.
-100,0...+1500,0 Pa [-0.4...6 in H2
SwemaMan 8 measures airflow with the use of a k-factor, it can also give an accurate measurement of air velocity when connected to a Pitot static tube (according to EN 16211 method ID 1, ID 3, ST 1, ET 1). The air flow can be displayed using the air velocity and the duct area. The area can either be entered as diameter, height x width or area.
SwemaMan 8 has a built-in barometer and thermo couple connector type K for correct air density.
SwemaMan 8 can calculate minimum, maximum and average values. Fifty measurements can be stored and transferred to a PC.
SwemaMan 8, thermo couple, 2 IEC LR6 AA batteries, calibration certificate & manual.

Differential pressure: -100...1500 Pa, -0.4...6 inH₂O
Resolution: 0,1 Pa, 0,1 Pa at 0.0....999.9 Pa, 1 Pa at 1000...1500 Pa
Air velocity: approx. 2...49 m/s, 390...9600 fpm (calculated)
Barometer: 600...1200 hPa, 18...35 inHg (integrated)
Temperature: 0...+50 °C, 32...122 °F (standard curve, Thermo couple connector type K)
Measurement Uncertainty at 23°C ±5°C:
Differential pressure: ±0,3% read value, min ±0,4Pa
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.
