OTT - Model WAD 200 -Weighing Rain Gauge with Automatic Drain
OTT WAD 200 - Weighing Rain Gauge with automatic drain. The OTT WAD 200 is a weighing rain gauge combined with a self-emptying weighing rain sensor specifically designed for the use in subtropical and tropical climates. Utilizing a highly sensitive measuring principle this precipitation gauge meets the requirements from the WMO guidelines. Additionally, the OTT WAD delivers accurate measured values in real time for both quantity and intensity of liquid precipitation in the range of 0.001 to 720 mm/h.
Unattended use in suptropical and tropical climate zones
The OTT WAD 200 is a weighing rain gauge combined with a self-emptying weighing rain sensor.
Meets WMO guide No.8
