The AZ 8911 Relative Humidity Anemometer is an excellent all-rounder when it comes to climatic temperature and condition controls. The sensor is attached to the unit by a curly cable, which allows the user to manoeuvre the sensor into tight locations or difficult to reach spots. A protective cap shields the temperature and humidity sensor which can easily be turned on and off to allow the AZ 8911 to take accurate measurements. Ideal for various HVAC applications and climate testing.
The AZ 8911 Relative Humidity Anemometer is well suited to HVAC (Heating, Ventilation, Refrigerating and Air Conditioning) applications and can also be used within the industrial sector for monitoring production environments and storage conditions.
AZ 8911 Relative Humidity Anemometer
A handheld anemometer with a remote vane probe that carries its own temperature and humidity sensor. It measures air velocity, air volume, temperature, relative humidity, dew point and wet bulb temperature for HVAC and industrial air flow work. A rotating cap protects the sensor when it is not in use.
- Remote vane with built-in sensor for temperature and humidity, protected by a rotating cap
- Measures 6 parameters air velocity, temperature, humidity, air volume, dew point and wet bulb temperature
- Quick to get dew point and wet bulb in seconds
- 8 points velocity average
- PC link via USB interface
- Max / min, hold and backlight
- Metric / imperial units
- Auto power off with a low battery indicator
- DC jack and tripod hole
When to use the AZ 8911 Relative Humidity Anemometer
Use the AZ 8911 when an HVAC or industrial air flow check needs air velocity, air volume and the condition of the air in one pass. The remote vane carries its own temperature and humidity sensor, so every reading comes from the same point in the airstream.
- 1Air speed and room conditions from one probeThe temperature and humidity sensor is built into the vane head, so one reading at a grille or duct gives air velocity, temperature, humidity, dew point and wet bulb temperature at the same point in the airflow. There is no need for a separate hygrometer for HVAC checks.
- 2Air volume across a grille or duct faceThe meter calculates air volume up to 99999 m3/minute, and the 8 points velocity average lets you take readings at several points across an outlet and get one averaged figure, which is how air flow is usually checked when commissioning or balancing ventilation.
- 3Reaching vents that are out of the wayThe vane is on a coiled cable that extends from 50 cm to 1.5 m, so you can hold the probe up to a ceiling diffuser or into an opening and still read the display in your other hand, where a one-piece anemometer has to go right up to the outlet with your eyes.
