The accelerometer is designed for quick measurements of an imbalance in machines and the examination of bearings and gears. The accelerometer is also frequently used to evaluate the state of small electronic motors. Meter can only be used for realtime measurement, no memory storage.

PCE-VA 20 is a air humidity meter for testing heating, ventilation and air conditioning or cooling (HVAC) systems. This air humidity meter features a 10 cm / 3.9" Ø fan impeller, easy-to-read backlit LCD, and functions such as display hold, average value, maximum value, minimum value, battery-saving automatic power off, low-battery indicator, and metric or imperial unit selection.

• Measures air flow velocity, volume flow, relative humidity, air temperature, dew  point temperature and wet-bulb temperature
• Air flow velocity range: 0.2 … 30 m/s (39.4 … 5905.5 fpm)
• Accuracy: ±(1.5% of measured value + 0.3 m/s) when less than 20 m/s, ±(3% of  measured value + 0.3 m/s) when more than 20 m/s
• Resolution: 0.1
