Apogee SQ-520 Quantum Sensor mit USB Output
The Apogee Instruments SQ-520 smart quantum sensor can be connected to a computer for taking spot measuements or graphing and datalogging real-time PPFD using the included software. The sensor can also act as a stand alone PAR datalogger by simply connecting it to any standard 5 V DC USB power plug. Internal memory within the sensor head is capable of storing 10,000 user-specified periodic measurements that can be downloaded as a CSV file to a computer for analysis.
