Turbidity Photometer
Measure The Difference In Light Transmitted
The in-line turbidity meter houses a light source and detector that measures the difference in light transmitted that is a result of the turbidity of the liquid.
Designed To Be Integrated To Monitor
There is no display or readout on the photometer/transmitter because it is designed to be integrated to a monitor with data acquisition capability or a control system via its transmitter function.
Overview
The PendoTECH Turbidity System is a compact photometer light source/detector equipped with an 880nm light source and fiber optic cables that connect to either the flow cell stand in which the single use turbidity flow cell is placed, or if a stainless steel flow cell, the fiber optics connect directly to the flow cell. The raw output of the transmitter is a milliamp (mA) signal that is scaled from 0 to 3Absorption Units (AU). In order to convert from AU to NTU, users must develop a correlation equation by taking samples of their stream and measuring its turbidity in NTU using an off-line instrument to develop the correlation. This step can be carried out only once to create the correlation for each unique stream. PendoTECH can provide estimations for a correlation based on NTU standards, but for best results one should be developed for each unique stream.
