Hot wire Thermo-anemometer ARW-911

Hot Wire Anemometer ARW-911

The hot wire anemometer is a professional instrument for measuring wind speed, temperature and flow rate of an air flow. It is designed for measuring wind speed in various environments, particularly suitable for measurements inside ducts and pipes thanks to the reduced size of the sensor and the telescopic probe which allows it to reach different points inside the duct. Equipped with various functions including a data memory (960 readings) and a software interface for PC connection.

This type of anemometer is applied in the measurement of the speed and flow rate of air flows inside factories, schools, offices, homes, in the control and testing of air conditioning, suction and air conditioning systems (HVAC).

"Hot Wire" measurement technology

The ARW-911 anemometer is equipped with a particular "Hot Wire" technology which allows for a small measuring probe usually used for reading inside the channels in heating, air conditioning, aspiration and ventilation systems . It is very simple to use, all you need is a small inspection hole to insert the probe and measure.

Another important feature is the sensitivity of this measurement principle which allows you to carry out speed measurements of air flows with very low values with a starting point of 0.2m/s, compared to the vane measurement principle which, being a rotary motion requires a starting point of 0.4-0.5m/s.

Main features of the ARW-911 Hot Wire thermo-anemometer

• The telescopic probe with a dimension of 74x35x1000mm (Length 1mt.Completely extended with articulated part at the head) becomes animportant advantage in the measurement of ducts, grates anddiffusers that are not always easy to reach.
• Calculation function of the minimum, maximum and average values of the speed of the air flows.
• Internal data memory 960 values (single or automatic value saving mode with sampling interval setting from 0 to 9999 sec).
• The ARW-911 hot wire anemometer is supplied complete with data interface with software and USB cable. (DOWNLOAD SOFTWARE)

Applications of the hot wire anemometer ARW-911

The hot wire anemometer is an ideal instrument to use in the industrial measurement sector, such as in the installation and maintenance activities of air conditioning, extraction, heating and ventilation systems in general:

• Environmental measurements in general for the analysis of HVAC microclimatic comfort
• Measurements of air flows and flow rates in the plant engineering sector, on diffusers, grilles and ducts for air conditioning, heating and ventilation
• Measurement of painting booths, extractor hoods, air speed produced by cooling fans

Two important notes to keep in mind for the use and care of the hot wire anemometer

• The thermoresistance sensor for measuring the speed of air flows is very delicate, so be careful not to subject it to very high speeds (over 25m/s) or to air flows carrying dust or impurities, contact with these particles at high speed it could damage or even break the sensor.
• Pay attention to the temperature of use which must be within the range of 0°÷50°C max
