Hot wire thermoanemometer AZ 8953

The AZ 8953 hot-wire anemometer is an advanced measuring device designed to precisely measure airflow velocity, temperature, and environmental parameters in ventilation and air conditioning systems. Thanks to the use of hot-wire technology , the meter provides very high sensitivity, especially at low flow rates , where traditional vane anemometers are often insufficient.

This model was designed for HVAC professionals, service technicians, and installers who require reliable and repeatable measurement results in the field. The device's design is based on proven solutions used in higher-end meters, while offering a very good price-to-performance ratio.

One of the device's key elements is a telescopic measurement probe terminated in a flexible gooseneck cable . This allows for measurements in hard-to-reach places – inside ventilation ducts, behind air vents, or in tight installation spaces. The probe's adjustable length , with a maximum range of 100 cm , further enhances comfort and allows for precise sensor positioning.

The T-AVG function allows the user to determine the average measurement value over a specified period (up to 1 hour), while the P-AVG function allows for calculating an average based on up to 999 measurement points. This solution allows for highly accurate assessment of flow parameters, especially in unstable system operating conditions.

Additionally, the device offers a choice of measurement units, increasing its versatility in everyday use. Users can change temperature units (°C / °F), airflow velocity (m/s, ft/min), and volume flow  (m³/h, m³/min, ft³/min, l/s), adapting them to specific measurement requirements or industry standards. The easy-to-read, backlit 26 x 44 mm LCD display allows for comfortable operation even in dimly lit areas, while intuitive operation makes the device convenient for both experienced users and those taking occasional measurements.

The AZ 8953 is powered by 4 x 1.5V AAA alkaline batteries. It features an automatic power-off function after 10 minutes of inactivity and a low-battery indicator. When the power-saving function is disabled, it can operate in continuous mode, for example, during long-term measurements.

APPLICATION
It can be widely used wherever accurate airflow measurement and control of ventilation system parameters are required. The device is ideal for measuring and regulating ventilation systems (HVAC), servicing and diagnosing air conditioning systems, monitoring the operation of heat recovery units and heat recovery systems, measuring the efficiency of air supply and exhaust vents, analyzing airflow in ventilation ducts, detecting leaks in buildings (e.g., at windows and doors), and monitoring indoor air quality.
