Light Sensors (Multiple) and Light Meter

The LINPAR is designed for the measurement of Photosynthetically Active Radiation (PAR) within plant canopies. 33 sensors are mounted within a 1 metre anodised "U" section tube. The sensors are covered with a 3mm diffuser providing an integrated reading over 850mm section of the sensor. At the cable end there are no sensors in the first 70mm and in the last 50mm at the distal end to provide for attachment. An integral "bulls eye" levelling sensor is provided.

For complete canopy monitoring solutions the LSM-LINPAR can be used with the SFM-1 Sap Flow Meter, PSY-1 Psychrometer and the DRL26 Dendrometer.

Features:

  1. Measure PAR light along at least 1 meter length. Suitable to measure PAR light above, within and below the canopy alone or simultaneously.
  2. The sensor can be directly connected to a Data Logger and the readout device Light Meter as device Light Meter as and when required.
  3. Quantum Sensor with suitable detachable cable and carrying case for field use.
  4. The quantum sensor suitable to be used in the temperature range of -20oC to +50 oC

Light Sensor Meter - Configured for LINPAR linear PAR (ceptometer)Sensors. 5 sensor capacity; ruggedized water proof IP68 rated enclousure; 24-Bit integrated digital micro-processor, internal Lithium – Polymer battery; voltage regulator; standalone logging capability to MicroSD card. Supplied complete with 2GB MicroSD card and enclosure mounting bracket; Windows configuration and communications software for downloading and manual operation of the instrument; User Manual.

Light Sensors (Single) and Light Meter

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
