200mm Collector Rain Gauge

The TR-525-W2 is a freestanding receptacle with an open top, called the collector, which allows rainfall to enter. The collector is specially designed to prevent splash-out and overflow, two possible causes for loss of accuracy during extremely heavy rainfall events. Collected water is siphoned into a mechanical device, the tipping bucket style rain gauge. The tipping bucket then incrementally measures the rainfall accumulation and causes a momentary closure of a switch. As water is collected, the tipping bucket fills to the point that it tips over. This action empties the bucket in preparation for additional measurement. Water discharged by the tipping bucket passes out of the rain gauge with no need for emptying.

Stock is single reed switch but if you like we will install a dual reed switch.

Should be used where snow or freezing weather may occur. It consists of two low-power heating elements that prevent disruption in readings during freezing times. The heaters are thermostatically controlled with an additional thermal overload.

This allows an extended range of accuracy. This system allows control of the "flow rate" of accumulated precipitation. This metering geometry assures higher levels in both accuracy and repeatability during periods of extremely heavy rainfall.

All our 525 rain gauges are factory calibrated. Option 1. If you would like the printed certificate included. OR Option 2. If you like to prepay for 3 separate factory calibrations when you send in your gauge for recalibration we offer it at a discount.
