With the climate meter it is possible to measure climate conditions such as temperature and relative humidity, as well as determining surface temperature of objects simultaneously by using the included external temperature sensor or using an infrared measurement. The climate meter offers features such as average value, maximum, minimum, and hold functions at a reasonable price.

• Internal probe
• Temperature: -20°C … 60°C / -4 … 140°F
• Relative humidity: 10 … 90% r.H.
• Temperature of global: -22°C … 60°C / -8 … 140°F
• Humidity: -68°C … 60°C / -90 … 140°F
• Dew point temperature: depending on the sensor

• External probe
• Temperature: -50° C … 500° C / -58 … 932°F

The PCE-313 A Climate Meter measures relative humidity and temperature and can be used in the air-conditioning sector. The PCE-313 A Climate 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 Climate 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. The meter comes manufacturer calibrated (ISO or as an option).

• 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)
