Photosynthetic Light (PAR) Smart Sensor(S-LIA-M003)

Overview

The Photosynthetic Light (PAR) Smart Sensor is intended to measure light intensity for the frequencies relevant for photosynthesis. This sensor has a measurement range of 0 to 2500 umol/m2/sec over wavelengths from 400 to 700 nm. Enclosed in a anodized aluminum housing with acrylic diffuser and o-ring seal, this model has a 3m cable; a light sensor bracket and light sensor level are recommended.

Also available in a wireless model for use with the HOBOnet Field Monitoring System.

Highlighted Features
