Digital anemometer can measure wind speed, temperature and calculate air volume
The digital display anemometer has the functions of measuring wind speed, air volume, wind temperature, and data retention; the speed of wind speed measurement is fast, and the temperature measurement is high. Can be used in environmental protection, ventilation, air conditioning, systems and other fields. Features a dual cast case for ease of use. High sensitivity, simple operation, data retention function. With temperature probe. Can measure temperature. Low power consumption, low battery reminder. Small size, light weight, easy to carry and use on site. Can be used in environmental protection, ventilation, air conditioning, systems and other fields. For cooling and heating coil analysis, diffuser and supply air vent testing, fume hood face velocity testing, indoor air quality testing and filter face velocity testing.
Digital anemometers can simultaneously measure and record multiple parameters in the ventilated air using one probe with multiple sensors. The instrument can measure wind speed, temperature and calculate air volume. With retractable straight probe, bendable articulated probe, a single probe with multiple sensors simultaneously detects and data records multiple ventilation parameters. It detects flow velocity and temperature, and calculates flow. The principle is that a thin metal wire heated by electricity (called a hot wire) is placed in the airflow, the heat dissipation of the hot wire in the airflow is related to the flow velocity, and the heat dissipation causes the temperature change of the hot wire to cause a change in resistance, and the flow velocity signal is transformed into electric signal. The method of use is simple and fast, with high precision and long service life.
The digital display anemometer is easy to operate, can measure temperature and wind speed at the same time, and can display up to three measurement parameters at the same time. Measures humidity, calculates volume flow, switches between actual/standard condition wind speed. A wind pressure sensor is installed on the wind speed uniformity, the sensor reflects the change of the wind speed, and adopts the pitot tube principle to automatically detect the wind pressure at multiple points and time points, and calculates the air volume according to the size of the base to generate the average air volume. The display of the air volume hood adopts PDA, and the large-screen LCD display is intuitive, and the data of wind speed, temperature and air volume can be obtained directly, and the recording time interval can be set for continuous parameter recording, so as to analyze the data.
A wind pressure sensor is installed on the uniform wind speed, which is used to measure the air volume flowing through various air supply outlets and diffusers, and can also measure the air volume of the return air outlet. It is mainly used to cover the air outlet and collect the air volume like a big horn. Focus on the average wind speed sensor on the base. It is based on the measurement of wind speed and can be widely used in heating, ventilation, air conditioning, environmental protection, meteorology, clean workshops, chemical fiber textiles, various wind speed laboratories and other occasions.
