LINPAR - Linear PAR Sensor
For determining PAR in plants
The LINPAR was developed to measure the photosynthetic ac-tive radiation (PAR) in plants. The 33 radiation sensors are mounted in a 1-metre long anodised “U” section tube and covered with a 3 mm thick diffuser.
With the Linear PAR sensor, an integrated analysis can be conducted over 850 mm, whereby no sensors at are present at the ends of the section tube (70 mm from the start and 50 mm from the end to allow for fastening among other things). An integrated spirit level helps level the sensor in the terrain.
For complete monitoring solutions, the LINPAR can be combi-ned with the SFM-1 Sap Flow Meter, PSY-1 psychrometer and DRL26 dendrometer.
- Integrated value of 33 sensors
- Ideal for use in plant canopies
It is ideally suited to be connected to the Light Sensor Meter (LSM). One LSM can support up to 10 LINPAR sensors for complete canopy light characterisation.
Variables calculated include PAR, leaf area index, sunflecks and canopy extinction coefficient.
