Introduction to the performance of photosynthetically active radiometers
Photosynthetic active radiation refers to the light wave of the specific wavelength range used by plants for photosynthesis. In English, it is Photosynthetic Active Radiation, abbreviated as PAR. Understanding and calculating photosynthetically active radiation is used to understand the reaction process of photosynthesis in plants. The quickest way to measure photosynthetically active radiation is to use photosynthetic active radiometers, photosynthetically active radiation recorders, and optical quantum meters to measure. The photosynthetically active radiation and the performance of its measuring instruments.
The unit of photosynthetically active radiation is micromoles per square meter per second, expressed in English as μmol/m2*s. There are also several units that represent photosynthetically active radiation: micro Einsteins, Footcandles, open streams W/m2, and Luminosity Lux. Although these units can express photosynthetically active radiation, there is no conversion relationship between them in practical applications. Because these photosynthetically active radiation units describe photosynthetically active radiation at different levels and in different aspects. If W/m2 is the total solar radiation, light waves of 400-1100 nm are measured. The μE measures a broad wave of 400-700 nm. It can be seen that different units have different ranges of measured light waves, so there is no comparison between them. This unit of photosynthetically active radiation remembers that the unit of measurement is μmol. Therefore, when calculating, the conversion is also performed and converted to μmol/m2*s.
This photosynthetic active radiation recorder is a professional recording instrument for measuring photosynthetically active radiation. It compensates for the shortcomings of previous recorders that can only set recording intervals and read data from a computer. One-touch switching allows manual recording. The sampling interval is set at any time from the computer to automatically record data. The instrument is small and exquisite, so it can be carried outside to operate. At the same time, the instrument can be placed in the field for a long time to take data. After the data is collected, the data can be sent to the computer. The software will automatically generate curve graphs, which can be printed and processed. , To facilitate our timely observation of data changes.
PVC / Foam Sign Board
PVC Sign Board named foam sign board by some other people .They are
widely used indoor and outdoor signs .Most are for the display case and wall
and other style displays . We can provide two kinds of printing process on the
pvc boards ,one is digital printing on the sticker ,then stick them on the
board ,this way is economic and you can change the graphic if the size is not
too large ,you can apply the stickers on the board times .The other one is uv
flatbed printing on the pvc sign boards , this way you can not change the
printed graphic ,the uv ink on the board is not washable and it will be strong
on the surface on the board ,concave-convex printing is available for our uv
printing on the boards . So it will appear to 3D effect ,you can touch with
hand for the concave- convex.
