芝田技研 Product Lineup

【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

■Free testing available If you would like to test whether the airflow of air purifiers, dust collectors, air conditioners, blowers, small cooling fans, etc., is functioning correctly, testing can be conducted at our in-house test center. Please contact us for conditions and details. The Wind Watcher α (WWA) can accurately measure airflow and pressure while suppressing disturbances through automatic control, enabling the visualization of appropriate airflow. The Wind Watcher can continuously flow a constant airflow through small test specimens, allowing for the investigation of heat transfer with a simple device. It is also possible to determine the suitable airflow for cooling, which is crucial for control panels and large medical equipment's exhaust heat. Airflow is accurately captured using the airflow meter 'Air Measure,' which has a rectifying function. 【Features】 ■ Capable of performing dual roles: "creating wind" and "measuring wind" ■ Displays the amount of wind created, measured airflow, air temperature, and air density ■ Operation via touch panel, with numerical displays for normal airflow and mass flow, as well as trend graph displays ■ Equipped with 3-channel analog output (4-20mA) ■ CSV data can be copied to USB ■ NETIS registration number: KT-240015-A *For more details, please refer to the PDF materials.

Please contact us for conditions and details. The Wind Watcher α (WWA) can continuously flow a constant airflow through test subjects such as masks due to its automatic control, allowing for the evaluation of permeability and pressure loss. When comparing and evaluating mask materials, a constant airflow is passed through the material, and the difference in pressure generated before and after the material indicates the quality of its permeability. While the adsorption performance of filters for dust and other particles is important, poor permeability can lead to energy loss in airflow, resulting in economic losses. Therefore, regular cleaning of filters is essential. The Wind Watcher can quantitatively capture the effects before and after cleaning. The airflow is accurately measured using the airflow meter 'Air Measure,' which has a rectifying function. ■NETIS Registration Number: KT-240015-A

The "Air Normalizer (ANL)" is a device that responds to various fluctuations in temperature and internal pressure, accurately displaying or outputting wind speed and volume. It digitally displays the corrected airflow based on the temperature and pressure within the duct, and can accommodate various differential pressure-type anemometers such as pitot tubes and orifices. Additionally, it presents measurement and calculation values as trend graphs. 【Features】 ■ 5-inch wide touch panel ■ Equipped with 4 channels each for analog input and output ■ Can be checked as a CSV file on a PC ■ Panel mountable for the touch panel section ■ Display units - Supports standard (normal) airflow, actual airflow, mass flow rate, wind speed, etc. * For more details, please refer to the PDF document or feel free to contact us.

The current airflow measurements are based on fluid dynamics, so it is necessary to streamline the flow within the duct. The gas flow method we propose, based on the principle of mass conservation, can accurately measure regardless of the turbulent flow in complex pathways or variations in airflow.
