Description
Overview
GAOTek wind speed hygrometer can measure the air speed, air velocity, air volume, temp., humidity, dew point and wet bulb temperature, which is the best choice as the wind speed monitoring device in HVAC (heating, ventilation, refrigerating and air conditioning) or industrial related application. The temperature and humidity sensors which could measure the low speed or velocity wind with high accuracy. It has extended van probe, which can insert to the high duct easily. The compact mini impeller is ideally designed for duct airflow. Duct temperature has no influence on airflow wind measurement. It is a microprocessor-based design. A must device for HVAC engineers uses. No need to whirl the meter or refer to the chart, easy to get wet bulb and dew point quickly.
Features
