Spherical PAR Sensor
Aquation’s Scalar PAR Sensors measure irradiance as PAR from all directions, enabling you to determine how much light is available at a single point in waters with significant upwelling, scattered and diffuse light.
Omindirectional light measurements are useful when calculating light use efficiency in cell cultures(e.g. electron transport rate) and light availability in natural systems including turbid estuaries or coral reefs with highly reflective sands.
- Scalar 4p sensors measure omnidirectional light
- Continuous measurements, logged data
- Sphere diameter:19 mm/ ¾inch
- Submersible
- Non-corrosive plastic
- WiFi links controller to your network
- PAR (400-700nm) to ~4000 mmol quanta m-2s-1
