Aquation has developed a range of chlorophyll fluorescence sensors for outdoor and indoor applications.  Each sensor can be connected to a computer or a stand-alone datalogger.

Shutter Sensor

• measures Fv/Fm and Φ_PSII with automated dark acclimating shutter (user defined dark acclimation interval)
• uses saturating pulse technique with white LED
• actinic treatments are user defined (duration and intensity)
• applies far red light for PSII deactivation
• waterproof to 50 m
• inbuilt cosine-corrected PAR sensor
• inbuilt temperature sensor
• Several (up to nine) sensors can be combined with the Submersible Datalogger for extended underwater monitoring

USB Standard Sensor (Simple Fluorometer)

• measures  Φ_PSII
• uses saturating pulse technique with white LED
• actinic treatments are user defined (duration and intensity)
• applies far red light for PSII deactivation
• operated directly from PC using Windows-based fully programmeable software

USB Wireless Sensor (Simple Fluorometer)

• all features of USB Standard Sensor plus:
• USB thumb-drive-like transmitter in PC communicates over 30 m (or more on request) to Interface Box
• Interface Box is 12 V DC powered (mains power or solar panel/battery combination)
• Cable from Interface Box to Sensor

USB Submersible Sensor

• all features of USB Standard Sensor plus:
• Submersible for aquaria use (3 m max) or field (50 m max)

USB Wireless Submersible Sensor

• all features of USB Standard Sensor plus:
• features of Wireless Sensor
• featrures of Submersible Sensor

Handheld Sensor

• all features of USB Standard Sensor plus:
• designed for one-handed operation using pistol grip
• trigger for saturating pulse measurement
• thmb-operated leaf clip for insertion of leaf
• PAR sensor (cosine corrected) on flexible stalk
• Leaf temperature sensor (optional)
• Cable from pistol grip to Portable Datalogger (worn over shoulder)
