Both portable and tabletop varieties of turbidity meters are available.  If you have more than one project location you may find it useful to rent or lease a tabletop and leave it in your laboratory, you could bring the samples from several locations there for testing.  Different units are calibrated to detect different levels of turbidity so be sure the meter you rent or lease is suitable for your needs.

The turbidity meter you rent or lease from the KWIPPED network of suppliers will have a sample port, a light source, sensors, a data display screen, and the electronics necessary to convert the data from the sensor into displayable units.  Most turbidity meters available will display in NTUs – nephelometric turbidity units – as designated by the EPA.

A sample of the water to be tested is gathered into a small test tube.  This is placed into the turbidity meter, a light is shone through, and sensors on the sides measure the amount of light scattered by the particles.  The light source can be infrared or white light and the sensors are frequently found at a 90-degree angle to the light source.

Turbidity is the measure of water clarity or cloudiness through the measurement of its light scattering properties.  Cloudy or hazy water is caused by particles suspended in the water; dirt, soil, or other organic compounds frequently cause this.  They can also be called turbidimeters and are a specific category of nephelometers.
