Anemometer PCE-VA 20

Portable instrument for precise measurement of air velocity and flow rate, temperature, relative humidity, dew point, and wet bulb temperature. Its compact design and reduced weight facilitate mobile measurements in installations, HVAC maintenance, quality control, and fieldwork. The winged wheel (Ø 10 cm) allows, with optional covers, measurement of volumetric flow as well.

Key Features:

• Air velocity measurement: range 0.2–30 m/s, resolution 0.01 m/s.
• Air temperature measurement: range -20…+60 °C, resolution 0.1 °C.
• Relative humidity measurement: range 0.1–99.9 % HR, resolution 0.1 % HR.
• Calculation and display of dew point and wet bulb temperature.
• Volumetric flow measurement (0…99.999 m³/min) with possibility of resolution and flow cover selection.
• Functions: extreme value recording, HOLD function, backlit display, automatic shutdown, and low battery warning.

Accuracy and Performance (Summary):

• Air velocity: accuracy <20 m/s: ±(1.5 % of value + 0.3 m/s); >20 m/s: ±(3 % of value + 0.3 m/s).
• Temperature: ±0.6 °C.
• Relative humidity: ±3 % HR (at 25 °C and between 10–90 % HR); outside that range ±5 % HR.
• Response time (temperature and humidity): approx. 60 s.
• Screen update: once per second.

Dimensions and Power Supply:

• Dimensions: 269 x 106 x 51 mm.
• Approximate weight: 200 g.
• Power supply: 4 AAA batteries.
• LCD display: 32.5 x 54 mm.
• Operating conditions: 0…+50 °C, humidity <80 % HR. Storage: -10…+50 °C, <90 % HR.
