Illumination is the basis of the physiological activities of plants and is an essential environmental factor, because only under light conditions, plants can perform photosynthesis, can synthesize organic matter, and there is no light. Everything else is talking about it. Light is an important environmental factor in plant physiology, ecology and agricultural production. Only those light that can be absorbed and utilized by plants are related to photosynthetic or dry matter accumulation. This portion of light is measured and measured in units of energy as a basis for photosynthetic efficiency or dry matter production efficiency. Such radiating scales are photosynthetically active radiation. Optical recorders are the main instruments for measuring light.
How the light quantum is converted by the unit The light quantum is an indicator of the intensity of the reaction light. The optical recorder is a scientific instrument that is specially designed for measuring light quantum. In addition, the optical recorder can record photosynthetically active radiation. There are three models. The optical recorder compensates for the shortcomings of previous recorders that can only set recording intervals and read data from a computer. One-touch switching can be done manually, or the sampling interval can be set at any time from the computer to automatically record data.
Photosynthetically active radiation can be measured with the aid of an optical recorder. The optical recorder is a dual-channel recording type that can simultaneously record two parameters of photosynthetically active radiation (unit: μmol) light intensity (unit: lux), store this data on the host computer, and can also import the data into a computer. Measurement range: 1-2,700μmolm-2s-1 (400-700nm) Reproducibility: Temperature 20°C-25°C, humidity 20%-80% ± 5% 1 Linearity: Full scale ±1% Resolution: 1?molm-2s-1 Spectral response: Bandwidth: 400-700nm Stability: Less than ±2% change/year Power supply: Standard 5 alkaline or NiMH, NiCd rechargeable batteries 4 Section Weight: 140g Ultraviolet Infrared Response: 0.5%.
Spray dryer is a machine which can utilize
different spary drying techniques to obtain powder , granule or block
solid product from
solution, emulsion, suspending liquid and pumped paste liquid. The speed of
drying is considerable,
the product made by the
machine has good uniformity, fluidity, solubility, high pure and high quality. The control and
operation are very
conveniet.
