Photon Meter


Product Description:

1.In plant growth and development process, the radiation factor plays an important role.

2.First of all radiation is the energy of plant photosynthesis, the process of photosynthesis influence the formation of production and product quality.

3.Secondly, as a regulation of the energy, it will play an important role to the development of plants morphology, leaves shape and size as well as from vegetative growth to reproductive growth rate changes.

4.Photons meter mainly used for agriculture, forestry and other research and production departments for PAR radiation measurement. Its characteristics are the spectral response simulation probe photosynthetic function effectively, digital show, portable compact, with good accuracy and stability.


1.Big-screen LCD, film-style keypad, can display real-time sampling date and time (year, month, date, minute, second), low-voltage warning, automatic shutdown.

2.GLZ-B model adopt RS232 interface, extract datum and import EXCEL for graphics, analysis software for free download and upgrade by computer.

3.Special suitcase, smart and convenient to operate in field.

Model difference:


Function  Difference


Without computer interface, can only store datum to the main controller


Communication interface: RS485 single- channel, with computer interface, can not only store datum to the main controller, but also import datum to the computer for processing



Communication interface: RS-485 double-channel, with computer interface, can record two parameters---PAR and illuminance, can not only store datum to the main controller, but also import datum to the computer for processing.
