S.W. Burrage EMS 7 PAR Meter

 
EMS 7 PAR Meter
 
  • EMS 7 is a portable photo system for the determination of the PAR (photosynthetically active radiation) above and within plant canopies.
  • As such it is very useful in plant physiological and ecological studies.
  • The system consists of two photo sensors: Reference and Sample.
  • The reference sensor is a 40 mm diameter PAR cell which is threaded for a standard tripod and is normally mounted above the canopy to be studied.
  • The reference sensor is linked to the sample box by a cable or a radio link.
  • The sample sensor is a PAR line sensor 850 mm in length which contains 32 cells covered by a diffuser giving a uniform integration over the sensor length.
