Technical Description

The Kalyx-RG has a standard low density plastic tipping bucket adjusted to 0.2 mm resolution and is produced from UV stabilised external materials.

Traditional cylinder-shaped rain gauges are inaccurate due to the effect of wind blowing over the orifice. The physical presence of the gauges causes air to accelerate, carrying rainfall away from the collecting vessel. The effect of this can be up to a 20% reduction in rainfall catch. The unique aerodynamic shape of this range of scientific standard rain gauges reduces this effect, ensuring a high level of confidence in the accuracy of your measurements.
