Quantité
The Apera Instruments TN400 provides fast and reliable measurements of the turbidity (turbidity) of liquids. The instrument is equipped with an infrared light emitting diode (860 ± 30 nm) and operates using a nephelometric 90° scattering method that complies with ISO 7027 and DIN EN 27027 standards for determining the turbidity of aqueous solutions. The large LCD with progress indicator and intuitive operating instructions in picture and text form make it user-friendly and easy to operate.
