PCE-313A Temperature MeterMeasures ambient temperature from -20 ... 60°C (-4 ... 140°F) and relative humidity from 0 ... 100% RH / Integrated data logger with adjustable sampling rate and SD card memory.
PCE-313A is a combination thermometer hygrometer used to measure the relative humidity (% RH) and temperature (°C / °F) of the air. Ideal for use in evaluating heating, ventilation and air conditioning (HVAC) system performance, this digital temperature and humidity meter also has a port for connecting a type-K thermocouple. This allows the user to take surface temperature measurements using an optional external type-K temperature probe (not included - see accessories).

The thermo hygrometer features a built-in data logger capable of recording humidity and temperature measurement data at an adjustable sampling rate in direct mode or permanently in data logging mode. To use these functions, you must program the meter in advance using the keypad. For permanent or long-term recording applications, we recommend powering the meter using an optional AC power adapter (see accessories for details). The device also comes with an SD card memory of up to 16 GB to enable long-term data acquisition as well as quick and easy transfer of the stored data to a PC for analysis via Microsoft Excel (.xls files saved to SD card).
