Quantum Sensors

Apogee Instruments quantum sensors measure photosynthetic light levels in both air and water, combining accuracy and durability at a competitive price. The sensor heads feature a unique blue diffuser that reduces spectral error to less than 5 % for sunlight (direct, diffuse, under plant canopy, reflected from plant canopy) and common electric plant lights (fluorescent, metal halide, high pressure sodium), and less than 10% for LEDs (blue, green, red, cool white, neutral white, and warm white).

The sensor has following special features

  • Next generation sensor head design
  • Excellent cosine response
  • Self-cleaning dome-shaped head
  • Potted solid for extreme conditions
  • Self-powered and amplified models
  • Installed in growth chambers from industry leaders Convirion, Biochambers, Environmental Growth Chambers, and Percival Scientific
  • Also available in multi-sensor “line quantum” models for spatially-averaged measurements
  • Fully submersible
  • Easily integrates with data-loggers
  • Four year warranty
