Turbidity can be calculated in the laboratory using a bench turbidity meter, in outdoor and field applications a portable turbidity meter would be used and for plant and process applications a permanent online controller would be used. Turbidity meters use an instrument called a nephelometer with the detector system to the side of the light beam. More light reaches the detector if there are lots of small particles reflecting the source beam than if there are few. The units of turbidity from a calibrated nephelometer are called Nephelometric Turbidity Units (NTU).

Dissolve Oxygen Meters
A dissolved oxygen meter is used to calculate the quantity of oxygen there in a unit volume of water. Now the next subject that arises is, why do I need to calculate the amount of oxygen in water? This is because it indicates if the water is useful for a specific application like water treatment plants, sewage treatment works, river monitoring and fish farming.

Spectrophotometers
Spectrophotometry involves the use of a spectrophotometer. A spectrophotometer is a photometer (a apparatus for measuring light intensity) that can calculate strength as a function of the light source wavelength. Important features of spectrophotometers are spectral bandwidth and linear range of absorption or reflectance measurement.

Digital Melting Point Apparatus
Digital Automatic Melting Point Apparatus is planned for quick and perfect detection of melting point. Feature packed & easy to use. This is an necessary bench top tool. This equipment has an arrangement to hold the capillary containing the sample in uniformly heating media. The hotness is indicated on a digital display readable in 1.0° C. At the point, when the sample melts, the heating is automatically cut-off and the digital display showing the temperature remains on the indicator till it is cleared.
