Swema 3000 is a multifunctional instrument and logger with external anemometers, temperature and humidity probes. It is designed for accurate ventilation testing and adjustment, aswell as for industry, research applications.
The instrument includes a number of specific measuring programs complying with EN 16211, 12599 or ISO 7730.

For the external sensor there is a wide array of measuring programs in Swema 3000. For example Comfort (CO) for the draught sensor, air flow in duct (APF) for anemometers, logging (LOG) and averge (AP) for all sensors.
Air flow / velocity: With an external anemometer the air velocity and air flow in a ventilation duct is calculated. (Measuring program APF according to EN 16211 method ID 1, ID 3)
Humidity: External sensors that measure relative humidity (%RH) and temperature. Swema 3000 presents also dewpoint (°C) and water content (g water / kg dry air).
Barometer and temperature is set in settings for automatic air density compenation.
Select Real or Standard air flow.
Since Swema 3000 has no internal sensors it is recommended to calibrate the instrument every 5 years.
External sensors are indivually calibrated and need not to be calibrated together with Swema 3000.
Swema 3000md (764202) with built-in sensors. Differential pressure -300...1.500 Pa with auto-zero valve, barometer and thermocouple connector.
Swema 3000mdH+ (764203) same model as Swema 3000mdH+, but differential pressure sensor has higher range. ±10.000 Pa.
Instrument, 2 AA standard batteries, two holders for SWA 31, USB cable, calibration certificate.
