Turbidity Measurements

Measure turbidities with the Turbiquant® instruments from EMD. We offer you solutions for measurements in drinking water, wastewater, industrial process water and in the food industry..

Our instruments are suited for both investigations in the laboratory as well as on-the-spot analyses. We have developed the various models of the Turbiquant® turbidimetry instruments with a focus on routine measurements. A feature they all have in common is their ease of use and high sample throughput.

Combining ultimate simplicity with speed

The advantages of EMD’s Turbiquant® system:

Turbidimeter

The Turbiquant® 1100 IR and 1100 T instruments are portable, battery-operated turbidimeters. The easy operation, the practical carrying case, and the waterproof casing that adequately protects the electronic components make the Turbiquant® 1100 IR and 1100 T the ideal instruments for on-the-spot analysis.

Turbiquant® 1500 IR and 1500 T have large and easy-to-read displays and can be operated simply with just a few buttons. The user is guided through the procedure via the display. A continuous-flow cell enables a high sample throughput.

With Turbiquant® 3000IR or 3000T you can select different measurement methods and result terms. The methods available are those of nephelometry, densitometry and ratio measurement. It is also possible to make continuous-flow measurements with a low-pressure continuous-flow cell using a purging gas.

Accessories for Turbidimeter

Both the Turbiquant® 1500 IR/1500T and the Turbiquant® 3000 IR/3000T can be used with a convenient pour-through assembly. This accessory simplifies measurement by providing a one-time cuvette alignment, simplified rinsing and the avoidance of gas bubbles.

Real continuous flow-through measurement is possible with the Turbiquant® 3000T/3000 IR by using the flow-through assembly together with the periodically measured value output via printer or PC. Dry air or nitrogen can be connected to the instrument via a pressure-reducing valve with adjustable flow. The instruments provide a connection for air rinsing, as, without this, condensation effects can distort the measured value.

Validated Quality Standards

To minimize your workload, EMD offers you ready-to-use, non-toxic calibration standards. AMCO-AEPA-1® Microspheres are cited as Primary Calibration Standards in compliance with USEPA Method 180.1 (see also Standard Methods for Examination of Water and Wastewater, 21st Edition (2005), Section 2130, Turbidity). The standards are also accepted as “Alternative Use Secondary Standards” equivalent to freshly prepared formazin suspension (Ref. EN ISO 7027).
