About this machine

The Hach 2100N is a laboratory turbidimeter — sometimes referred to as a nephelometer — designed to measure the turbidity of liquid samples across a wide measurement range. Turbidimeters of this type are essential instruments in water quality analysis, environmental monitoring, and process control applications, where accurately quantifying the cloudiness or haziness of a liquid is a regulatory or operational requirement. Hach is a well-established manufacturer of water analysis instrumentation, supplying laboratory and field measurement equipment to industries including municipal water treatment, environmental science, and industrial process monitoring.

This unit offers a measuring range of 0 to 4000 NTU, making it suitable for both relatively clear samples and significantly turbid ones without requiring manual range switching across the full span. It supports three measurement modes — NTU, EBC, and Nephelo — giving operators flexibility to work within different reporting conventions depending on the application or industry standard. The instrument is EPA-compliant and carries UL/CSA certification, confirming that it meets recognised safety and performance standards for laboratory use.

The light source is a tungsten lamp, a conventional choice in laboratory turbidimetry that ensures consistent and stable illumination for accurate nephelometric readings. A bidirectional RS232 serial interface is included, allowing the instrument to communicate with computers or data-logging systems for recording and transferring measurement results.

Operationally, the unit functions within a temperature range of 0 to 40 °C and a maximum relative humidity of 90 %, making it compatible with standard laboratory environments. It is rated for 115 V AC operation and has a weight of 3.43 kg, reflecting its compact bench-top form factor. This example is offered used, located in Spain, and is priced at $1,750.
