With the air humidity meter you can ensure the right climate in your office. The air humidity meter measures the CO2 content of the air, the relative humidity and the room temperature. The air humidity meter shows carbon dioxide concentrations up to 9999 ppm, temperatures from -10… 50 °C, and relative humidity values from 20… 95%.

• Large CO2 measuring range up to 9999 ppm
• Traffic light function for carbon dioxide
• Measures temperature and humidity
• Network operation
• Suitable for classrooms, offices, lecture halls
• incl. ISO Calibration Certificate (for CO2 only)

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

The air humidity meter has a CO² measuring range of 0 … 9999 ppm. In addition to the carbon dioxide measurement, the air humidity meter also has a carbon monoxide (CO) sensor with a measuring range of 0 … 1000 ppm and a temperature and humidity sensor.

The air humidity meter records the air temperature as well as the relative humidity and the barometric pressure and saves them internally on an SD card. The compact device with a large memory (up to max. 16 GB SDHC card) is primarily used for long-term registration in the food sector (refrigerated counters in department stores, refrigerated transports, warehouses) as well as for measurement and recording in industry (heating and cooling processes, machine temperatures, product storage, etc.).

Measuring ranges

• Temperature: 0 … 50 °C /  32 … 122 °F
• Relative humidity: 10 … 90% r.h.
• Barometric pressure: 10 … 1100 hPa (mbar)
• Selectable pressure unit: hPa, mmHg and inHg
• Real-time data storage
