AQUAlogger 210 TY

The AQUAlogger 210TY turbidity, temperature and pressure logger is a compact, self-contained data logger that operates at depths of up to 4000m. It is suitable for use in freshwater and marine environments.

 

Using the established AQUAtalk software provided, you can choose your sampling intervals, whether to continuously or burst sample, and whether or not to average data. The internal batteries last up to a year, depending on the sampling regime, with external batteries available for extended deployments.

The fixed and auto gain options for the turbidity sensor mean you don’t have to compromise on your measurement range. If you want to focus on a particular turbidity range, choose the most suitable fixed gain. If you want to capture a wider range of variability, select the autogain function, and let the instrument choose the most appropriate option for each burst of samples.

The AQUAlogger 210TY has real time reporting capability as standard and can be combined with cables or the AQUAmodem Op1L.
