LOGBOX SE Data Logger: Analogue and Digital Inputs

Kipp and Zonen LOGBOX SE is a data logger with analogue and digital inputs that allow connection to multiple instruments at the same time.

The state-of-the-art design consumes so little power that it will run for weeks on the six internal AA type batteries. A wide range of DC power sources can be used and the logger can manage the power from a solar panel and charge an external battery. These features make it suitable for months of unattended operation in remote locations.

LOGBOX SE is an ideal data logger for many applications in solar energy, meteorology, climatology, hydrology and agronomy.



Kipp and Zonen LOGBOX

The Kipp and Zonen LOGBOX SE has an IP 65 weatherproof enclosure and a wide operating temperature range, from -40°C to +60°C.

LOGBOX SE is supplied with Windows™ software to make configuration and data download fast and simple, using RS-232 serial communication or the internal USB port. Input channels are programmed by selecting a voltage range and defining the calculation to convert measurements to engineering unit values, including polynomial functions. The data logger programme is held in non-volatile internal memory.

The internal GSM/GPRS quad-band 2G modem accepts a full size SIM card and can send the logged data at a selectable interval, from 1 to 24 hours, to a designated e-mail address or FTP server.

The Kipp and Zonen LOGBOX SE has a battery-backed real-time clock and this can be synchronised daily with a time server, if the data service supports it. The logger is supplied with a mounting bracket and clamps for fixing to poles up to 50 mm diameter.

The measurement interval (sampling rate) can be down to 1 second. The logging interval can also be down to 1 second, but is typically 1 minute and usually includes the average, minimum, maximum and standard deviation of the measurement values. LOGBOX SE is created to be compatible with the requirements of the Baseline Surface Radiation Network (BSRN).
