In-Situ has announced a new line of fluorometers compatible with the company’s popular Aqua TROLL 500 and Aqua TROLL 600 Multiparameter Sondes. The line, which will be available soon, includes: Rhodamine WT, Chlorophyll a, Phycocyanin (BGA-PC), and Phycoerythrin (BGA-PE) sensors, ideal for lake and river monitoring as well as coastal studies.
The sensors will be the latest addition to the Multiparameter water quality platform, which allows for wireless data collection via the VuSitu mobile app. Overall, the company is excited to introduce an expanded set of sensors for users looking to streamline fieldwork and reduce monitoring costs.
“With our patented Integrated Optical Compensation technology our sensors provide greater stability at low limits of detection and have significantly reduced sensor drift over temperature and time” says Steven Sewell, Product Manager. This allows for earlier identification of concentration changes, ultimately enabling more effective decision-making and intervention.
Representing a significant technological advance, In-Situ’s fluorometers are the only sensors In the multiparameter water quality market with 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.
Sewell also points to other distinctive aspects of the new fluorometers, including:
- Isolated Optical Frequencies: Using two or more sensors simultaneously typically creates interference among sensors. Our sensors use separate frequencies, providing a unique digital signature for each light source to minimize interference and improve accuracy.
- Ambient Light Rejection: External light can introduce bias in your data, but our fluorometers block external light for reliable performance in any setting and separates the light from the sensor and other ambient light sources.
- Low Interference Spectral Bands: Unlike combined Chlorophyll/BGA sensors that measure wide ranges of the visible spectrum at once, our sensors excite a smaller, targeted range of the light spectrum which increases accuracy and minimizes interference.
“We’ve designed our sensors and multiparameter sondes with features such as our Integrated Toolkit, VuSitu™ Mobile App, and Onboard LCD Display so you’re not left struggling in the field,” Sewell says. “Our smart sensors retain calibration information and allow the user to configure their instrument with just the parameters they need.”
Sewell says the upcoming release is aimed at delivering on the company’s commitment to innovating easy-to-use water monitoring tools that provide the highest accuracy. “We really do want to be our customers’ eyes in the field, and to do that we know that first and foremost they need trustworthy data.”
