Light plays a crucial part in plant and crop growth. Absorption of light drives the photosynthesis process whereby CO2 and Water are photo chemically converted into glucose and Oxygen. The light a plant uses for this process is called Photosynthetic Active Radiation (PAR). The PQS 1 is designed to measure PAR light, in the wavelengths of 400nm and 700nm.
The PQS 1’s sensitivity has been optimized to provide reliable and accurate measurements regardless of the PAR source, either from natural light or artifical light sources, eg. high pressure sodium lamps, making the PQS 1 instrument perfect for studies of crop growth in green houses or out in the field.
The mounting flange incorporates a bubble level and adjustment screws, for easy leveling. A threaded hole takes the accessory screw-in mounting rod for fitting to masts and poles. Two PQS 1 sensors can easily be bolted back-to-back, and fitted with the mounting rod, to make a simple PAR albedometer. The standard cable length is 5 m, with an option of 15 m.
