Microprocessor Based Turbidity Meter

The ANALITE 160 turbidity meter is the latest of our range of turbidity measurement instruments.

It is designed to operate with either an ANALITE retro-scatter (180°) probe or an ANALITE 90° probe - to be specified at time of order. The ANALITE 160 turbidity meter allows the user to set up measurement parameters through a user friendly menu system displayed on the in-built 2 line alphanumeric display.

Measurements can be read directly from the display at any time or downloaded to a computer/printer through the optional RS232 output at user selectable periodic intervals.

The NEP160 will power up automatically to its last settings whenever external power is applied making it ideal for logging applications when using the analogue output or optional RS232 port.
