Mengenal Turbidity Meter.

Turbidity meter merupakan alat pengujian air limbah yang berfungsi untuk mengukur tingkat kekeruhan air. Turbidity meter disebut juga alat ukur kekeruhan air. Seperti kita ketahui ada banyak penyebab tercemarnya air di sekitar kita, misalnya limbah air rumahtangga, industri, pertanian, peternakan, dll. Untuk itu kita memerlukan sebuah alat yang bisa membaca tingkat kekeruhan air yang akan kita teliti, alat inilah yang kita kenal dengan nama Turbidity Meter.

Adapun prinsip kerja dari turbidity meter ini adalah kira-kira sebagai berikut : Turbidity meter ini akan memancarkan cahaya pada sampel air yang akan diteliti dimana kemudian cahaya itu akan  diteruskan dan dipantulkan sehingga menembus media atau sampel tersebut, dari situ turbidity meter akan mengukur dan mentransfer kedalam bentuk angka yang merupakan tingkat kekeruhan.ah penting dalam bidang medis, biologi, kimia, ilmu makanan, oseanografi, dan bidang-bidang lainnya.

Apa yang Dimaksud dengan Turbidity ?

Turbidity atau yang sering disebut dengan kekeruhan disebabkan oleh adanya material yang tersuspensi.

Nilai Unit yang digunakan sesuai dengan Standar ISO adalah FNU ( Formazine Nephelometric Unit ) sedangkan EPA biasanya menggunakan NTU ( Nephelometric Turbidity Unit ).

Dua metoda lain yang sering digunakan untuk mengukur turbidity atau kekeruhan adalah JTU ( Jackson Turbidity Unit ) dan Silica Unit ( mg/L Si02 ).

Conductivity/ TDS Meters

Definition of Conductivity
Electrical Conductivity is the ability of a solution to conduct an
electrical current. Current flow in liquids carried by ions is different
from metals, where is carried by free electrons. Ions are formed
when a solid such as salt is dissolved in a liquid to form electrical
components having opposite electrical charges. The sodium
chloride separates to form Na+ and Cl- ions. All ions present in the
solutions contribute to the current flowing through the sensor and
therefore, contribute to the conductivity measurement. Conductivity
can be used as a measure of the concentration of ions present in
the sample.

Conductivity Units
Electrical conductivity is the reciprocal of electrical resistivity.
Electrical resistivity uses the unit of ohm meter or © x m. Rather than
use the units ©  1 x m 1, in 1971 the unit “ siemens” ( symbolized by the capital letter S) was adopted by the General Conference on
Weights and Measures as an SI derived unit.

The unit for electrical conductivity becomes siemens per meter. The
siemens unit is named after Werner von Siemens, the 19th century
German inventor and entrepreneur in the area of electrical
engineering. Previously to the siemens per meter unit, mho/ cm was
used to measure conductivity, where the unit “ mho” is a reciprocal
ohm. The “ mho” is the “ ohm” spelled backwards. Because of the
history of conductivity, micromho/ cm and millimho/ cm is commonly
translated to microsiemens/ cm and millisiemens/ cm because they
correspond one-to-one.

The unit of measurement commonly used is one millionth of a
Siemens per centimeter ( micro-Siemens per centimeter or ¼ S/ cm) .
When measuring more concentrated solutions, the units are
expressed as milli-Siemens/ cm ( mS/ cm) . For ease of expression,
1000 ¼ S/ cm are equal to 1 mS/ cm. Often times conductivity is
expressed simply as either micro or milli Siemens.
