Rain Gauge - OTA OSK15180T

This is the standard precision instrument NIWA uses throughout New Zealand in the National Climate Network, and elsewhere, for rainfall measurement.

This tipping bucket raingauge provides a single contact closure output each time a bucket fills with a specific volume of water, tips and activates a switch. It's constructed with corrosion-resistant materials and has screens to exclude insects and debris. The raingauge has a built-in level to help you install it correctly.

Each output contact closure represents 0.2mm of rainfall. There's also a 0.5mm option.

It's accurate to within 2%, at a rainfall intensity of 100mm/hour.

We can advise on, supply, service and calibrate all tipping bucket raingauges.
