Output: Backscatter signal strength in decibels as volts or digital value (formula provided for conversion to concentration)
Sample Volume Location: 5.5 cm from sensor face.
Operating Frequency: 8MHz
Tolerant to biofouling
Calibration over 30-400 micron sizes: flat to within ±30%; [compare with ±400% for optical turbidity sensors]
Calibration for fine particles below 30 microns: response follows d^1.5
Analog, SDI-12 and Digital (RS232) outputs available on the underwater connector
