The LOGBOX SD is an 8 channel data logger that allows connection to multiple instruments at the same time. Each input can convert measured values into engineering units. The data is stored on a 512 MB SD memory card that is included as standard.
Collecting meteorological parameters is a joint effort of a measuring instrument, such as a pyranometer, and a data logger. The low-level passive outputs of our instruments require accurate data logging. The LOGBOX SD is the perfect logger for all solar radiation and meteorological applications. The 24 bits high resolution differential analogue inputs can be easily configured for all our instruments, including the Pt-100 and 10K thermistor temperature sensors fitted to many of our models.
Four digital inputs are available for measuring time or frequency, or as counter inputs. LOGBOX SD has an IP 65 weatherproof enclosure and wide operating temperature range from -40°C to +60°C. The state of the art design consumes so little power that it will run for months on the four internal AA type batteries. The wide power supply operating range makes it possible to use solar panels or other external DC power sources.
The low power consumption, large storage capacity, wide temperature range and weatherproof box allow for months of unattended operation in remote locations. These features make LOGBOX SD the perfect logger for field use or in a complete solar monitoring station.
LOGBOX SD is supplied with user-friendly computer software to make configuration fast and simple, using RS 232 serial communication. All Kipp & Zonen radiometer settings are pre-defined and can be selected from a pull-down list. Any other sensor can be programmed by selecting an input range and defining the calculation to convert to the correct engineering units.
The logging and storage intervals can be set separately and the total storage time will be shown. An internal memory of 128 kB is present and, like the 512 MB SD card, this memory is non-volatile. Even without batteries the data will remain stored. The LOGBOX SD comes with a mounting bracket for fixing to poles up to 50 mm diameter.
