PCE-MMK 1 is a portable handheld air humidity meter used to measure the moisture content of wood, paper, textiles, concrete and other building materials. This multifunction air humidity meter also measures ambient temperature and ambient relative humidity.

Measuring ranges:

• Wood, paper, textiles: 1 … 75% moisture
• Concrete, building materials: 0.1 … 2.4% moisture
• Ambient temperature: -40 … 70°C / -40 … 158°F
• Ambient relative humidity (RH): 0 … 100 % RH

PCE-VA 20-SET is a air humidity meter with capture hoods for assessing and balancing heating, ventilation and air conditioning or cooling (HVAC) systems. This air humidity meter possesses a 10 cm / 3.9" diameter fan impeller and a bright backlit LCD. The functions of the air humidity meter incorporate display hold, mean value, max value, min value, battery-saving auto shutdown, low-battery display, and a choice between metric and imperial units.

• 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°C / 0.18°F
• Includes 2 x capture hoods (1 x round 210 mm / 8.3" Ø, 1 x square 346 x 346  mm / 13.6 x 13.6 in)

The PCE-313A air humidity meter measures relative humidity and temperature and can be used in the air-conditioning sector. The PCE-313A air humidity meter can be connected to type K thermo-elements to detect, for instance, the temperature of a wall by means of a surface probe. The internal memory of this test equipment allows the air humidity meter to record humidity and temperature data at an adjustable measurement interval. Thanks to its SD memory card (1 to 16 GB) the humidity test instrument can be used for long term data acquisition.
