PCE-VA 20 is a thermo hygrometer for testing heating, ventilation and air conditioning or cooling (HVAC) systems. This thermo hygrometer 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

The vibration analyzer is used as a hand-held measuring device for the individual assessment of vibrations on machines and systems. With the help of this vibration analyzer, the actual state can easily be determined on site. Thus, corresponding changes can be made directly on site after the measurement. 

- Frequency range: 10 Hz ... 1 kHz
- Measures speed, distance, acceleration in metric units
- Holds the reading after each measurement
- Easy to handle and battery operated
- Standard probe: 10mm

- Frequency range: 10 Hz ... 1 kHz
- Measures speed, distance, acceleration in metric units
- Holds the reading after each measurement
- Portable and battery operated
- Needle probe: 45mm / 1.77"
