Tower rain and precipitation sensor
Rain-O-Matic Tower rain and precipitation sensor with our patented self-emptying tipping bucket is a reliable low cost high quality rain gauge ideal for small weather stations and irrigation/soil moisture management.
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 Tower as your rain guage.
RAIN-O-MATIC Tower patented self-emptying tipping bucket is one of the most accurate and reliable rain gauges on the market. It gives you benefits in:
- 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 Tower delivered machine calibrated with 1 mm resolution as standard. Accuracy: +/- 5 %.
Our Rain-O-Matic Tower 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. 100.073: PCB No. 9601 (NC—normally closed) has male connection and 1 reed switch.
- Item no. 100.074: 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.
The Rain-O-Matic tower is light (220 g) but rugged which makes it perfect for:
- Small weather stations
- Irrigation/soil moisture management
- Outdoor sport facilities
- Hoppy Gardeners
