AQUAlogger 210TY Sensor Specifications

The AQUAlogger 210TY uses the tried and tested SeaPoint STM turbidity meter. The STM has four switchable gain ranges. These can be pre-set by the user or automatically selected by the AQUAlogger for maximum dynamic range in field deployment conditions.

Light Source Wavelength 880 nm
Scatterance Angles 15 - 150 degrees
Linearity <2% deviation 0 - 750 FTU
Measurement Range 0.01 FTU to >750 FTU over four automatically switched gain ranges. Above 750 FTU the sensor is non-linear.
Operating Temperature 0ºC to 50ºC
Dimensions (exc connector) 225mm (8.9") long x 70mm (2.8") diameter
