About this item

The degree of turbidity is a measure of water quality - a liquid is cloudy if it contains undissolved suspended matter such as particles or bacteria.

Battery power for over 5000 measurements
Improved precision, ready to use and non toxic standards
Portable, battery powered for on the spot analysis

These particles scatter incident light in many directions. The light scattered at 90 degrees is measured. Nephelometry is the measurement of turbidity. The clearer a liquid, the lower the turbidity. The units of turbidity are nephelometric turbidity units (NTU). Drinking water has max. of 5 NTU, sewage more than 2000 NTU.

Certifications: ISO 7027 an IR LED (infrared) light source with a wavelength of 860 nm is prescribed (IR models). USEPA method 180.1 and also APHA-AWWA-WPCF require the use of a tungsten lamp emitting white light (T models). AMCO-AEPA-1® microspheres are primary standards conform with USEPA method 180.1. In compliance with EN ISO 7027, these standards count as alternative secondary standards to fresh formazine.

Delivery: Each Turbiquant requires the appropriate set of calibration standards to be purchased separately.

Caution: No GLP function.
