Product Description
Veinasa-Jfs a Revolutionary Net Radiometer Pyranometer Solar Radiation Net Irradiance Meter
Veinasa-JFS A Veinasa-Jfs a Revolutionary Net Radiometer Pyranometer Solar Radiation Net Irradiance Meter is a new type of net meter developed on the basis of the traditional net radiation meter. It solves the shortcomings of the traditional net meter, such as often inflating it with balloons (once/3 days), frequently replacing the polyethylene transparent film (once/months), poor sealing performance, easy entry of water, manual maintenance, etc. We now adopt an imported transparent material as a filter cover to make it achieve fully sealed, non inflatable, free maintenance and other aspects. This technology has become a new breakthrough in the domestic net radiation meter, reaching the level of similar advanced products abroad.

Operating Principle of Veinasa-JFS:
The sensor on this meter is a rapid response line, multiple electro-plating thermoelectric piles, which has the advantage of fast response, wide spectrum response, good linearity and stable operating.
When two sensor surface with optical black paint are exposed to different light radiation, their respective thermoelectric reactors are heated to form a cold and hot junction, resulting in a thermoelectric potential. When the solar radiation is greater than the ground radiation, the output is positive and vice versa.

In order to be able to penetrate the long wave radiation, the new type of P.V plastic hemispherical membrane is used as the protective cover, and the whole sealing form is adopted in the title to prevent the formation of condensation.
Veinasa-Jfs a Revolutionary Net Radiometer Pyranometer Solar Radiation Net Irradiance Meter can be applied to:
Transpiration calculation, thermal stress and thermal balance research in the fields of meteorology, agriculture and forestry, building science, road safety, etc.
Highway condition monitoring
Q: Are you a factory/manufacturer?
A: Yes, we are professional factory/manufacturer of weather station and relative weather sensors. We also have hot sale and widely used weather sensor Veinasa-SFS, which is to measure scattered radiation.
Q: What's the common power supply and signal output?
A: Common power supply and signal output is DC12-24V, RS485. But we can customize for you as demands.
Q: How can I collect data?
A: If you have your own data logger, you only need to buy our sensor and meanwhile we send you communication protocol. If you do not have, we can add our data logger for you, also provided with English software, which can help you read, inquire and download data.
Q: What's the lifetime of this Net radiation table sensor?
A: At least 5 years long. Every sensor has its own calibration certificate or testing report.
Q:What's the delivery time?
A: Usually, we dispatch goods in 3 working days after receiving your payment. But it depends on your quantity.
Q: May I know your warranty?
A: Yes, usually it's 1 year. We can send you detailed warranty document if needed.
