Reliability, accuracy and durability. That is the basic thought behind the design of the HD2013. Completelyconstructed of corrosion resistant materials, the HD2013 rain gauge is built to withstand even extreme conditions.To guarantee a wide range of use, depending on the environment where the rain gauge is placed, there is a choicebetween heated or non-heated version.The principle of a tipping bucket rain gauge is simple: depending on the quantity of rainfall, the tipping bucketmechanism fills and empties. Every tipping action operates a reed contact: in this way, counting the quantity ofthe rainfall. This means that the tipping bucket has one enormous advantage: it needs no power supply to operate.Power supply is only a necessity when circumstances demand heating because of low environmental temperatures.Reading the number of counts, in other words reading the rainfall, can be done by using a datalogger. This can bea rain indicator datalogger such as HD2013-DB as well as a datalogger of the HD33 series with built-in 4G/3G/GPRSmodem for a direct communciation of the measured data to the Delta OHM Cloud or a to an own secured server.When ordering, the rain gauge is completely setup to be used. Easy to install, adjustable feet and leveling deviceintegrated. Bird spikes and accessories for raised mounting available.

HyQuest Solutions’ TB4 Series II is ahigh-quality tipping bucket rain gaugefor measuring rainfall in urban and rurallocations. Due to the integrated syphon,the gauge delivers high levels of accuracyacross a broad range of rainfall intensities.The tried and proven design of the TB4Series II ensures long-term, accurate andrepeatable results. It is manufactured fromhigh quality, durable materials ensuringlong-term stability in the harshest of
environments. It consists of a robust pow-der-coated aluminium enclosure, a UV-resis-tant ASA polymer base, a teflon bucket, and
stainless steel fasteners and finger filter.TB4 Series II provides a finger filter thatensures the collector catch area remainsunblocked when leaves, bird droppings andother debris find their way into the catch.The base incorporates two water outletsat the bottom allowing for water collectionand data verification.

The RHD is a low-cost, high precision, ultra-robust
rain gauge. It features very low- power con-sumption, is maintenance- free and has a com-pletely sealed acoustic sensor with no moving
parts. The sensing device is a polished stainlesssteel hemisphere supported by a strong stainless
steel arm. It detects changes of the acoustic pres-sure that are induced by the impact of raindrops or
hailstones. The RHD also includes a distrometerthat return the drop size distribution.
It features continuous or pulse analog voltage out-puts and supports SDI-12 communication, serial RS-232, and Modbus RTU RS485 (using an optional
adapter). The full configuration of the sensor can be
customized at any time with a Plug-and-Play PC con-nection or remotely, using serial commands.

MeteoRain® 200 Compact uses a self-balancing measuring principle. Itoffers high resistance to error producting effects as found in most rain gauges. Theseinclude soiling of the internal measuring mechanism, mechanical friction, residual waterremaining in the measuring spoon from previous rain event, and debris. Additionally,MeteoRain® offers high resistance to vibrations and non-level mounting.

Mount the rain Gauge where it gets a clearmeasurement of precipitation– away from overhangs,etc.The mounting arm is designed to fit over a strap 0.75”(19 mm) wide. Two 0.25” (holes 6.35 mm) are placed0.75” (19 mm) part.
