The PCE-VA 20 is a Condition Monitoring Anemometer for testing heating, ventilation and air conditioning or cooling (HVAC) systems. This Condition Monitoring Anemometer 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

• 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"

• Automatic range: 30 … 130 dB
• Manual ranges: 30 … 80/50 … 100/80 … 130 dB
• Resolution: 0.1 dB
• Accuracy: ±1.4 dB
• Data logger function for 32,000 values
• Including sound calibratorSound calibrator for recalibrating sound measuring devices. Sound measuring devices are delivered pre-adjusted, the sensor of the device is subject to a temporal drift, with the sound calibrator you can always re-calibrate the sound measuring device independently and thus have continuously optimal measurement results. The sound calibrator is an optimal addition to the sound meter.Class II Acoustic Sound Calibrator

The PCE-T236 is a digital handheld condition monitoring tachometer or rotation meter for both contact and non-contact measurement. This condition monitoring tachometer measures rotation speed as well as linear or surface speed, displaying units in rpm, m/min or ft/min. A unique feature of this condition monitoring tachometer is that the orientation of the 5-digit LCD screen automatically rotates 180° to accommodate either contact or non-contact measurement.

• Optical laser measurement range: 5 … 99999 rpm
• Contact measurement range: 0.05 … 19999 rpm
• Accuracy: Less than 60000 rpm = ±0.05% fs , Greater than 60000 rpm = ±0.15% fs
• Incl. ISO calibration certificate
