Orion AQUAfast AQ4500 Turbidimeter

Thermo Scientific Orion AQUAfast IV AQ4500 Turbidimeter

The Orion AQ4500 Turbidimeter offers advanced features not available on any other benchtop or portable turbidimeter. The AQ4500 offers a dual source LED which allows readings that comply with both EPA 180.1 and ISO 7027. Turbidity can be read in the range of 0-1000 NTU with a choice of units: NTU, FAU, FNU, ASBC, and EBC. In the range of 0-40 NTU the AQ4500 offers a ratiometric range which will give EPA, GLI method 2 equivalent numbers. This portable field unit is truly IP67 waterproof with typical battery life over 1000 hours on one set of batteries and datalog capacity of 100 points which can later be downloaded to a printer or computer. The AQ4500 accepts 24 mm cuvettes and comes with a two year warranty.

  • Nephelometric and Ratiometric measurements
    with Autoranging
  • Data log capacity of up to 100 data points
  • Readings in the range of 0-1000 NTU with a choice of units: NTU, FAU, FNU, ASBC, or EBC
  • Includes Turbidity Standards kit, rugged carrying case, and replacement cuvettes
  • Orion AQ4500 is IP67 waterproof to a depth of 3 meters

LaMotte 2020we

LaMotte 2020we & 2020wi
Portable Turbidity Meters

The redesigned 2020 water turbidity meters combine an advanced microprocessor with a unique patent pending optical chamber resulting in greater accuracy and a wider range.

The multi-detector optical configuration assures long term stability and minimizes stray light and color interferences.

All readings are determined by the process of signal averaging over a 5 second period. This minimizes
fluctuations in readings attributed to large particles and results in rapid, highly repeatable measurements. Ideally suited for both low-level drinking water applications and monitoring high turbidity in the field.

  • Seven user selected languages – English, Spanish, French, Chinese, Japanese, Italian, and Portuguese.
  • Waterproof to IP67.
  • Automatic range selection from 0.05-4000 NTU.
  • Tube positioning ring limits vial variability.
  • Easy menu driven operation and large LCD display.
  • 500 point data log, stored results can be viewed directly on instrument or downloaded to a computer via USB cable.
  • 2020we version meets USEPA design criteria as specified by USEPA method 180.1.
  • 2020wi version meets design criteria for quantitative methods of turbidity using optical turbidimeters as specified by ISO 7027.
  • Kits are supplied with 0, 1, and 10 NTU standards, sample bottle, four sample tubes, USB cable and USB wall plug.
