maPress Duo

Hand held instrument for precision measurement of pressure, flow velocity, temperature and other parameters...
Three channel precision manometer for pressure, suction and differential pressure. Every combination of the multiple pressure channels is possible.
Precision draught, pressure and differential pressure measurement. High accuracy coupled with a resolution of 0.1 Pa and an IR printer interface make the instrument ideal for chimney draught and air-conditioning testing. A range of options and additional features makes the instrument even more attractive.

Notes:

1) The temperature measurement channel type K (Ni-CrNi) is standard equipment in the pressure meter. An appropriate probe for the measurement is available as an option.

2) The temperature mesurement channel type Pt500 is standard equipment in the pressure meter. An appropriate probe for the measurement is available as an option, either for temperature measurement alone or combined with a sensor for relative humidity.

3), 4), 5) The accuracy of the measurement channel in hte pressure meter is valid only if the pressure meter has been warmde-up for at least 20 minutes, is in an immobile horizontal position and that a zero has been carried out within the previous 15 minutes.

4) The quick-fit connections will leak if used for suction measurements. For suction measurements connect the tube directly to the nipple on the pressure meter.
