The PCE-313 S Digital Thermometer has been designed for professional use in fields such as the air-conditioning sector. The PCE-313 S Digital Thermometer determines both relative humidity and ambient temperature. The PCE-313 S Digital Thermometer 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 the PCE-313 S Digital Thermometer allows you to record humidity and temperature values, with a freely adjustable measurement rate for real-time measurements or data storage thanks to its SD memory card (1 to 16 GB). The PCE-313 S Digital Thermometer can be programmed in advance via the keypad so the device can record values without the need to be present during the process. For long-term records, we recommend powering the PCE-313 S Digital Thermometer by means of a power adapter (optional). Recorded values can be transferred to a PC for further analysis (.xls file on the SD card). This property allows you to check measured values or design a graph by means of the Excel calculation program.
