Small rain sensor
Rain-O-Matic Small rain sensor with our patented self-emptying tipping bucket is a reliable low cost high quality rain gauge ideal for small weather stations, irrigation/soil moisture management and drain water measurement in drip irrigation.
For 30 years we have supplied more than 220.000 rain gauges to 41 countries on 5 continents and we deliver our products to OEM customers only and we are not competing with you for the end user. Download datasheet here.
Features and benefits
Beneath is listed the features and benefits of choosing Rain-O-Matic Small as your rain guage.
RAIN-O-MATIC Small patented self-emptying tipping bucket is one of the most accurate and reliable rain gauges on the market.
- More accurate measurements
- Only one adjustment screw which makes it easy to recalibrate.
- Bucket made in POM, which is a more dismissive material and therefore makes dust and dirt not stick so easily on the spoon and maximize water release.
Our Rain-O-Matic Small comes standardly as machine calibrated with 1 mm resolution. Accuracy: +/- 5 %.
Our Smalll rain gauges require minimal maintenance due to:
- Outer shell is made from ASA which makes the surface easy to clean.
- High quality plastic materials and a simple design for a very long durability (10-20 years)
Rain gauge/Tipping Spoon
Rain-O-Matic Small measures the precipitation by means of a funnel (orifice 50 cm2), which leads the water down into the self-emptying tipping POM spoon, held in place by a hard ferrite magnet.
The magnet always exerts just enough tension to allow the measuring spoon to empty in one quick movement (less than 300 ms) and then return to its normal position, ready to once again collect precipitation. This means the counter weight always remains the same opposite to other conventional two spoons tipping bucket rain gauges.

ASA plast materials
The rain gauge made in molded thermoplastic, also known as ASA, which has high outdoor weather ability.
ASA is extremely resistant against the sun’s UV radiation, it is frost‐ and heat resistant, standing all climatically conditions.
The product is widely used in the automotive industry as well as several other outdoor applications.
The electronic printed circuit board with individually tested and high quality reed switches protected against extreme weather conditions such as extreme frost or heat. This include corrosion from salt water due to the PCB is coated with weather-resistant varnish.
The printed circuit board comes in two versions:
- Item no. 100.053: PCB No. 9601 (NC—normally closed) has male connection and 1 reed switch.
- Item no. 100.054: PCB No. 9602 (NC—Normally closed, NO—Normally open). Terminal strip with 4 connections / 2 outlets and 2 reed switches, connected-up in series by 1 kohm and 1/4W resistor.

Agriculture benefits from a rain gauge
With the help of a rain gauge you are able to measure the precise amount of precipitation that is needed to water your crops. That’s why a rain gauge can optimize your water use and reduce production costs. Our rain gauges and precipitation gauges are equipped with a self-emptying tipping bucket-technology which makes it one of the most accurate measuring instruments on the market.
