About This Product

The Apogee PRI sensor measures PRI (Photochemical Reflectance Index). PRI is calculated from the reflectance of 531nm (green) and 570nm (yellow) and is an indicator of photosynthetic activity. In addition, there are upward and downward sensors, making it suitable for a variety of applications. The sensor is fully submersible and has a sturdy aluminum housing suitable for use in harsh conditions. The sensor cable includes an IP68 marine grade stainless steel connector that allows the sensor to be removed and easily replaced for maintenance or calibration.
