This is a known issue with Logger pro version 3.8.6.2. Saving a file with the Vernier Emissions Spectrometer (VSP-EM) connected and reopening the file will inadvertently and incorrectly set the spectrometer collection mode to transmittance. It also e...
The equipment you need to study wind energy in a classroom depends on the grade level and what activities you are interested in doing. A comprehensive list of KidWind kits and books based on grade level and activities can be found here: Which KidWind...
The Vernier PAR Sensor is calibrated before shipping and should not need user calibration.
However, you can calibrate the sensor using the Clear Sky Calculator (www.clearskycalculator.com). The Clear Sky Calculator for Quantum Sensors reports the...
Vernier PAR sensors are calibrated before shipping. Each sensor head is calibrated through side-by-side comparisons to reference Apogee Instruments SQ series quantum sensors that are checked against LI-COR model LI-190 reference quantum sensors....
Yes, the sensor head of any Vernier PAR sensor is waterproof up to the plastic box that contains the electronics. This box is often called the "sensor box". This means that the PAR sensor head and cable can be submerged in water up to the sensor box....
The main part of the a Vernier PAR sensor is a water proof sensor head. The end of the cable is attached to a voltage amplifier located inside a black electronics box. The sensor head consists of an acrylic lens, filter, photodiode, and signal proces...
Radiation that drives photosynthesis is called photosynthetically active radiation (PAR) and is defined as the total amount of quanta across a the spectral range of 400 to 700 nm.
The summed amount of light across this range is called the photosy...
Debris on any PAR sensor lens will partially block the optical path and will lead to low readings. Dust and other organic deposits are best removed using water, or window cleaner. Never use an abrasive cleaner on the lens. Salt deposits can also accu...
For instructions on applying a correction factor to the PAR sensor readings, seeHow do I apply a Correction Factor to Vernier PAR sensors?
For most cases you will not need to use a correction factor when measuring Photosynthetic Photon Flux Densi...
