PCE-VA 20-SET is a multifunction relative humidity meter with capture hoods for assessing and balancing heating, ventilation and air conditioning or cooling (HVAC) systems. This combined hygrometer-anemometer-thermometer possesses a 10 cm / 3.9" diameter fan impeller and a bright backlit LCD. The functions of the 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.

The PCE-313A Relative Humidity Meter measures relative humidity and temperature and can be used in the air-conditioning sector. The PCE-313A relative 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 relative 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.

• Relative humidity: 5 … 95% r.H.
• Temperature: 0 … 50°C / 32 … 122°F
• Type K: -50 … 1300°C / -58 … 2372°F
• Calculated dew point: -25.3 … 48.9°C / -13.5 … 120°F
• Wet bulb temperature: -21 … 50°C / -5.8 … 122°F
• Memory: SD card (1 … 16 GB)
• incl. ISO Calibration Certificate

The Relative 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
• incl. ISO Calibration Certificate

The PCE-HT 71N Relative Humidity Meter detects air temperature and humidity and stores readings to its internal memory. This Relative Humidity Meter is compact and has enough memory to store up to 32,000 readings, 16,000 for each parameter, and is used above all as a Data Logger, in supermarket refrigeration units, refrigerated transport, warehouses and other temperature controlled environments.

• Measurement range: 0 … 100% RH / -35 … 70°C / -31 … 158°F
• Accuracy: ± 3% RH (20 … 80%) and  ± 5% / ± 1°C (1.8°F)
• Resolution: 0.5% RH / 0.1°C (0.18°F)
• Memory: Max. 32,000 measurement data (16,000 for each parameter (humidity / temperature))

PCE-330 is a multifunction relative humidity meter or detector with a quick-response sensor for determining ambient temperature, relative humidity and dew point temperature. Equipped with an easy-to-read dual display, this data-logging indoor air quality (IAQ) meter features a large internal memory with storage for up to 16,000 recorded values.

• Temperature range: -20 … 60°C / -4 … 140°F
