Multi-channel profile radiation measurement, optionalcosineOr Scalarradiation
Biosphere Instruments Corporation of AmericaBIS underwater photosynthetic effective radiation profilerUsed for measurementThe cross-sectional optical radiation changes of underwater photosynthetic effective radiation (400-700nm),The BIS can integrate depth and temperature sensors.
BIS (spherical) of Scalar radiation
An underwater BIS that integrates temperature and pressure sensors (optional) can provide a vertical profile of solar radiation within a water depth of 100 m.
The BIS is very lightweight and its dynamic range (greater than 5 levels) design can meet the needs of different underwater working environments.
BIS itself does not require a battery!After BIS is connected to the computer, all data collection tasks are carried out through the computer.Work with LOGGER software based on Windows operating system.

Technical parameters
Data acquisition and communication
BIS uses the serial port (RS-232) to directly connect to PC or digital cable.The output signal of the photodetector is converted by 24-bit A/D and is quickly transmitted to the computer in binary.
powered by
This system consumes very low power, with power consumption of less than 2 mA per channel.A BIS consumes less than 12 mA power.
Sensitivity and dynamic range
Noise equivalent irradiance is 10-6withoutECM-2yes-1.The maximum irradiance in the air is generally 0.45withoutECM-2yes-1.The dynamic range that the instrument has is affected by the measured wavelength and the average time of the data acquisition system.When data is collected directly without evenly, the instrument has a dynamic range of 5 levels; when the average data time is 10 s, the instrument has a dynamic range of 6 levels.
