HD2013-DB
Rain gauge data logger
HD2013-DB is a data logger that has been specifically developed to capture and store rainfall
trends. It works with a long life lithium battery that provides, together with the large memory,
remarkable recording capacity without user intervention.
For user convenience, the supplied
lithium battery, when exhausted, can be also replaced by three alkaline batteries (not supplied
with instrument).
The backlit display shows in real time the rain quantity during various time intervals and the
maximum rainfall intensity in mm/h during the last hour and the last 24 hours.
The instrument is perfectly watertight thanks to the use of reed relays, instead of the common
push-buttons. The reed relays are operated through a magnet, attached to the end of an
aluminium handle tied to the case. When not in use, the magnet is placed back into its holder.
The software
HD32MTLogger
supplied with the instrument allows setting of the parameters of
the instrument, the real time display of the values captured by the data logger, the download
to a PC and the process of the stored data. The connection to the PC is made via the M12 8-
pole RS232C serial connector placed at the bottom of the instrument.
HD2013-DB can be connected to the most popular types of rain gauges with normally closed
(NC) or normally open (NO) output contact.
The display auto power-off feature allows to prolong the battery life. A front LED lets you check
the operating status of the instrument when the display is off. The LED changes color when the
rain gauge contact switches, thus allowing to verify that the rain gauge tipping bucket returns
correctly in the stable position after emptying.
