Multi-functional vane anemometer for measuring air speed, air flow, air temperature and infrared temperature / Adjustable measuring units / Large LCD with backlighting / Suitable for measuring low air velocities
The vane anemometer's easy-to-read LCD screen is backlit, enabling use in dimly lit areas and low light conditions. The large display shows air speed (velocity) measurements in m/s, km/h, t/min, knots or mph. Air flow measurements are depicted in CFM or CMM, while air temperature and IR temperature measurements are displayed in °C or °F. A built-in laser light serves as an orientation point for targeted infrared temperature measurement. (Please note that measurement of the ambient air temperature is automatically deactivated when using the laser sighting tool for infrared temperature measurement.) Therefore, the vane anemometer has many practical applications, including but not limited to the testing, adjusting and balancing of heating, ventilation and air conditioning (HVAC) systems and exhaust fans. Because the impeller is on a 1.2 m (3.93 ft) long cable, measurements can be carried out inside otherwise inaccessible ducts or HVAC system components with the information collected, processed and viewed on the meter or on a PC in real time.
Different anemometer products are designed for different usages. When choosing an anemometer, one should consider the anticipated air speed range (e.g., low flow, mid flow or high flow velocity measurement) and the location where the measurement will take place (e.g., inside an HVAC duct or outdoors in natural wind conditions). A vane anemometer is suitable for measuring air flow indoors and wind speeds outdoors. Since wind never has a very stable or monotonous flow direction, a vane anemometer can be adjusted to follow the changing direction of the wind to measure the correct speed. Vane anemometers are characterized by high sensitivity, making them the ideal tools for measuring even the smallest wind speeds. This makes vane anemometers suitable for monitoring whether drafts occur in schools, offices and healthcare facilities. The same applies to agriculture, since sufficient air conditioning of livestock stalls and stables is important for successful care of the animals. For the measurement of hot air flows, a vane should be thermoresistant. An advantage of this type of anemometer is that it is resistant to contaminants that can gather in ducts and ventilation systems. A vane anemometer also is a good auxiliary tool during various construction tasks and in mining. The vane itself is reliably protected and thus, damage risk during operation is low.
The vane anemometer may be also associated with a weather vane, due to its function to detect the direction of the wind. For some applications, it is a big advantage, and that is why this is one of the points to pay attention to when choosing the right model of the vane anemometer. The speed of rotation absolutely depends on the wind masses and may be very changeable. This feature is also extremely helpful, since it allows detecting the slightest deviations from the norms, for example, in the ventilation systems.
Exactly the slightest deviations often remain overseen and underestimated. Nevertheless, a sudden failure in the ventilating system or insufficient / excessive circulation of the air masses in the environment may lead to the temperature increase or decrease, change of the oxygen concentration in the air, which may be of crucial importance and even devastating. It goes not only about providing comfortable working conditions in the office, or pleasant environment at home, but about safety and even life protection. Application of the vane anemometer for monitoring and control ensures that people or animals do not turn out to be in dangerous conditions as a result of some weather parameters fluctuations or failures in the systems. Typical places and activities, like sailing, sport competitions inside, underground/subway stations, entertaining activities, movies, theatres, circuses, cattle concentration in the closed stables, pigsties or cowsheds especially for exhibitions, auctions, poultry farms may get dangerous really quickly if the conditions change even slightly. Without auxiliary devices it is sometimes impossible to feel and notice the changes, and if the valuable time is lost, this may lead to enormous losses and risks. Vane anemometer in no time is able to register the current parameters and indicate whether there is some dangerous shift in the common values or not.
