Achieve indoor and in-flight airflow monitoring! An anemometer that quantifies and records airflow.
The WA-790 is compact and lightweight, making it easy to move and install at measurement locations. It accurately measures airflow disturbances caused by equipment in clean rooms and changes in airflow within narrow devices. It visualizes points that have been overlooked and those that could not be measured, contributing to a better understanding of the actual conditions. 【Features】 ○ New digital processing utilizing DSP (high-speed processing unit) enables reliable data acquisition. ○ Compact design that integrates the conventional connection box and main unit (can be fixed to a tripod using standard mounting brackets). ○ Probe cable extended to 5m to suit the usage environment (previously 3m). ○ No moving parts, allowing measurements to follow transient changes from very low winds (approximately 0m/s). ○ Ultrasonic method eliminates the need for calibration due to temperature changes.
