Aqua TROLL Chlorophyll a Sensor (P/N 0038900) - OVERVIEW

This sensor measures chlorophyll a and is compatible with the Aqua TROLL 500 and Aqua TROLL 600:

Measurement range: 0–100 RFU, 0–1000 μg/L
Linearity: R² > 0.999 for serial dilutions of Chl a in MeOH across the full range
Resolution: 0.001 RFU or 0.01 μg/L

Features:

Integrated Optical Compensation: In-Situ’s patented technology uses a second detector to compensate for LED drift over temperature and time, providing more accurate, stable measurements.
Ambient Light Rejection: External light can introduce bias in your data, but In-Situ’s fluorometers block external light for reliable performance in any setting.
Low Interference Spectral Bands: Combined chlorophyll and BGA sensors measure wide ranges of the visible spectrum. In-Situ’s individual BGA sensors detect smaller ranges to reduce environmental interference.
Isolated Optical Frequencies: Using two or more sensors simultaneously typically creates interference among sensors. In-Situ’s sensors use separate frequencies, providing a unique digital signature for each light source to minimize interference and improve accuracy.

Benefits:

More accurate, reliable data: Improved stability and minimized interference mean better overall data.
Less maintenance: Internal diagnostics, lower calibration solution volume and one- or two-point calibration mean you spend less time on maintenance.
Reduced monitoring costs: Install only the sensors you need, so you don’t have to buy what you won’t use.
Ease of use: Sensors retain calibration data so you can use them in any sonde.
Versatile applications: Use the sensor for river or lake monitoring as well as coastal studies.
