Details

The OTT Parsivel2 is an advanced laser-based disdrometer for comprehensive measurement of all precipitation types.  Accurate yet economical, the Parsivel2 captures both the size and speed of individual preciptation particles and a signal processor classifies the type of precipitation as well as the amount and intensity.


  • Accurate - measures the size and speed of individual precipitation particles, then computes all necessary meteorological parameters
  • Maintenance-free - no moving parts or collection bucket that would traditionally require regular maintenance
  • Durable - continuous, precise precipitation data in all environmental conditions and integrated overvoltage protection
  • Energy efficient - low power consumption and flexible separate controlled head heating
  • Flexible communication - standard ports for RS-485, SDI-12, USB, and impulse for connecting to a datalogger, automatic weather station (AWS), or laptop
  • Innovative design - robust aluminum housing and symmetrically arranged measuring heads prevent moisture from affecting laser band direction

Questions & Answers

| Ask a Question
Can the sensor head freeze?
An automatic heating system prevents ice buildup on the sensor heads. A temperature sensor in the sensor head takes readings every second and the heating system adjusts according to the value. The sensor head is held at a constant temperature of at least 10 degrees C. Optimum heating output can be guaranteed with a supply voltage of 20 V DC.
What type of precipitation can my Parsivel2 measure?
The Parsivel2 can measure 8 types of precipitation: drizzle, drizzle/rain, rain, mixed rain/snow, snow, snow grains, sleet and hail.

Lake Michigan Yellow Perch Bounce Back After Commercial Ban

For decades, commercial fishing for yellow perch was allowed in southern Lake Michigan. This persisted until 1996 when it was outlawed, giving perch stocks there some time to recover. Scientists had for some time assumed that this fishing ban would not affect the reproduction cycles of the perch quickly and that they were going to need a long time to revert back to the cycles they relied on before commercial fishing ever started. But new research led by scientists at Purdue University finds that maturation schedules of yellow perch in southern Lake Michigan are much more resilient than had been previously thought possible.

Colorado River Fish Contain Levels Of Selenium, Mercury

Largely seen as pristine and relatively untouched by human activity thanks to its protected status, the portion of the Colorado River flowing through Grand Canyon National Park is anything but, according to recently published research. This is evidenced by high levels of selenium and mercury found in the fishes there. Scientists from many institutions were involved in the years-long work, full results of which have been published in the journal Environmental Toxicology and Chemistry. It was led by the U.S. Geological Survey, but perhaps the contributors from Idaho State University got the best end of the stick. They were looking into the food webs of the river to evaluate concentrations of selenium and mercury gathering in fish.

Heron dipper-Tough Is Ready For Harsh Deployments

For all the straightforward groundwater monitoring applications that the folks at Heron Instruments help with, there are a few that are far from typical. These include projects that take place near remediation sites or not far from waste disposal operations. Realizing that customers working in those sorts of projects are in need of a more robust option, the company has released the dipper-Tough . The new water level meter takes inspiration from Heron’s popular dipper-T , while throwing in a host of improvements that environmental pros working in groundwater can really appreciate.
