Product Description
Veinasa-GH wifi based solar radiation photosynthetically active radiation sensor
Photo-synthetically active radiation meter, also called Quantum number, is used to measure photo-synthetically active radiation of natural light in the wavelength range of 400 to 700nm. It can be connected directly to a digital voltmeter or data logger. The meter uses a silicon photo-detector and passes a 400-700nm optical filter.When illuminated by light, a voltage signal proportional to the intensity of the incident radiation is generated, and its sensitivity is proportional to the cosine of the direct angle of the incident light. Each photosynthetic active radiation meter gives its own sensitivity and can be read directly.

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 soil sensor TR-TS.
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 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 3-5 working days after receiving your payment. But it depends on your quantity.
Q: What's the standard cable length?
A: Its standard length is 2.5m. But it can be customized.
Q: May I know your warranty?
A: Yes, usually it's 1 year. We can send you detailed warranty document if needed.
