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).
