■A data logger developed for the purpose of acquiring and storing rainfall trend data. ■Long-term data recording is possible due to the built-in long-life lithium battery and large-capacity memory. ■If the built-in lithium battery is depleted, it can be replaced with standard alkaline batteries (3 units, not included with HD2013-DB). ■Using the software HD32MTLogger, which can be downloaded from the website, it is possible to set parameters for the data logger, display real-time measurements obtained by the logger, download data to a PC, and process stored data. ■Connection to a PC is made using the M12 screw RS232C 8-pin serial connector located at the bottom of the logger case. ▲Continuous operation for approximately 5 years with lithium batteries and about 1.5 years with alkaline batteries. ▲Resolution can be set from 0.050 to 1.599 mm/pulse. ▲Storage of 32,255 data points with large-capacity memory, RS232C serial I/F. ▲IP67, dual-display backlit LCD, red/green status indicator LED.
