Description
In-Situ™ Aqua TROLL® Chlorophyll a Sensor for Use with Aqua TROLL® 500/600, 0038900
Features:
- Designed for maximum stability at low detection limits to detect harmful algae bloom sooner than other sensors
- Uses patented Integrated Optical Compensation — a second detector to compensate for LED drift over temperature and time for increased accuracy and stability
- Measures chlorophyll separately from blue-green algae to reduce interference for more reliable data
- Blocks external light to reduce bias
- Measure wide range of the visible spectrum using chlorophyll a sensor in combination with the blue-green algae sensors, with each sensor detecting smaller ranges in order to reduce environmental interference
- Each In-Situ™ fluorometer sensor uses a separate frequency providing a unique digital signature for each light source to minimize interference between sensors when used in combination
- Internal diagnostics, lower calibration solution volume, and one- or two-point calibration means less maintenance is required
- Reduces monitoring costs because only necessary sensors to monitor the parameters of interest need to be purchased
- Sensors retain their calibration data so they can easily be transferred to different sondes
- Fluorometer sensors can be used to monitor rivers, lakes or coastal waters
