Residential airtightness/ventilation airflow measurement device Wind Watcher α Handy
[Joint Research with Tokyo Denki University] Measuring airtightness and ventilation airflow of detached and multi-family houses with a single device.
【Air Tightness Measurement】 - By being installed indoors, it can accommodate both depressurization and pressurization measurements, making it less susceptible to the effects of wind that can be problematic when installed outdoors. - It automatically measures and displays/records up to 10 points of indoor/outdoor differential pressure between 10 to 50 Pa (arbitrary). In high airtightness houses, the gap area is small, resulting in low airflow, but it can be measured with high precision up to 10 m³/h. - For airflow measurement, we use a differential pressure type pitot tube with rectifying function called 'Air Measure', which is calibrated with suction nozzles (JIS standard calibrated products) for each product. - The measurement method complies with JIS A 2201. By using a suitable micro differential pressure gauge (with automatic switching detection using two-stage differential pressure ranges) and Air Measure, we enhance the reliability of the measurement values. 【Ventilation Airflow】 - To ensure that the pressure difference inside and outside the collection hood is '0', the airflow of the auxiliary fan is controlled by PID, eliminating human error. - With the measuring equipment installed indoors, both supply and exhaust airflow can be measured simply by changing the flexible duct. - It can measure airflow with high precision up to 10 m³/h, making it possible to measure the airflow of natural air supply openings in living spaces. *NETIS Registration Number: KT-240015-A
