FIRE Chlorophyll Fluorometer

The Fluorescence Induction and Relaxation System (FIRe) is the latest advance in bio-optical technology to measure variable chlorophyll fluorescence in photosynthetic organisms.

The FIRe technique is based on active stimulation and highly resolved detection of the induction and subsequent relaxation of chlorophyll fluorescence yields on micro and millisecond time scales. The system is the result of 15 years experience in phytoplankton physiology, photosynthesis and primary production assessment.

• Sensitive enough for dilute field samples (down to 0.05 mg/m3 Chl a)
• Comprehensive suite of fluorescence parameters (e.g. Fv/Fm, sPSII, Fv´/Fm´)
• Independently controlled Blue and Green LED excitation
• Rapid, user friendly measurement protocols
• Optional Actinic Light Source for light adapted fluorescence measurements and automated light response curves
• Optional Fiber Optic Probe for multichannel analysis
• Optional Flow-Through Cuvette for software controlled continuous sampling onboard research vessels
