OTT Parsivel² - Laser Weather Sensor

Laser precipitation disdrometer measuring all precipitation types

The OTT Parsivel² is a modern laser disdrometer for comprehensive measurement of all precipitation types. The Parsivel² captures both the size and speed of falling particles, classifying them into one of 32 separate size and velocity classes.

  • Precipitation type, intensity, drop size distribution, radar reflectivity
  • Laser (optical)
  • Simultaneous measurement of 32 classes for particle sizes and velocities
  • SDI-12 / RS-485, pulse
Lufft Visibility Sensor VS2k - detection of visibility, fog, dust - road application, road weather, traffic weather rwis

Visibility Sensor VS2k-UMB

New product version of the known Lufft VS20 visibility sensor with a measurement range of 10...2000m, easy calibration functionality, sea waterproof housing and (active) spider defence
