The PCE-VA 20 is a versatile air humidity meter for determining environmental conditions such as wind, temperature and humidity. It is additionally used to test heating, ventilation and air conditioning / cooling (HVAC) systems. This air humidity meter device has a 10 cm / 3.9" Ø fan impeller and a clear backlit LCD. Available functions include display hold, average / maximum / minimum value, auto shutdown, low-battery warning, and metric / imperial choice.

• 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
• Incl. ISO Calibration Certificate

The Air Quality Carbon Dioxide Meter PCE-WMM 100-ICA consists of a main unit and a remote display.

PCE-WMM 50-ICA is a wall-mounted air quality carbon dioxide meter that uses diffusion to monitor carbon dioxide (CO2) gas levels and ambient temperature (ºC / ºF) indoors. This indoor air quality carbon dioxide meter features an alarm-activated potential-free contact that can, for example, activate a fan to reduce CO2 gas concentration in the room.

• CO2 gas measurement range: 0 … 50,000 ppm
• Temperature measurement range: 0 … +45 ºC / +32 … +113 ºF
• IP54-rated enclosure on sensor and remote display units
• 2 adjustable alarm thresholds
• 3- to 4-digit remote display (depends on range)
• incl. ISO Calibration Certificate

The air quality meter is specially designed for long-term monitoring of climatic conditions in, for example, offices, classrooms or lecture halls. The air quality meter is equipped with various sensors.
