Quantum Meters

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 Meter has following special features :

  1. Next generation sensor head design
  2. Excellent cosine response
  3. Self-cleaning dome-shaped head
  4. Sensors are potted solid for extreme conditions
  5. Also available in multi-sensor “line quantum” models for spatially-averaged measurements
  6. Four year warranty
  7. Model





    Specification :

    Spectral Range: 410 nm to 655 nm
