Description
Turbidity standard ROTI®Calipure 400 NTU is a ready-to-use calibration reference for nephelometric turbidity measurement in environmental laboratories. The 400 NTU level supports higher-range instrument verification, calibration curve setup and routine quality control in water and wastewater analysis. Physical characteristics include a density of approximately 1 g/cm³, a boiling point of 100 °C and a flash point of 250 °C, aligning with aqueous reagents handled under normal laboratory conditions. This ROTI®Calipure preparation from manufacturer Carl ROTH is intended for turbidity measurement within environmental analysis, particularly water and waste water testing. Laboratories can use the 400 NTU value to assess instrument linearity, confirm detector response at elevated turbidity and maintain consistent nephelometric performance. The glass pack format suits controlled analytical suites that require stable, defined standards for reliable turbidity results.

Questions about Turbidity standard, ROTI®Calipure 400 NTU, 100 ml, glass
What is this article?
Turbidity standard, ROTI®Calipure 400 NTU, 100 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dissolved oxygen & multiparameter meters, inside pH & electrochemistry, in Lab instruments.
A dissolved-oxygen meter reads oxygen in a liquid, optically or with a Clark cell. A multiparameter meter adds pH, conductivity or both on one instrument. The sensor cap or the membrane is the consumable. A reading in air and a reading in water are different calibrations.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
Which category should I open next?
