3. Mechanical Description The equipment is offered in a compact cast aluminum case, SAE-323 with lower oxidation power, treated against corrosion, finished with epoxy-electrostatic paint and expanded polypropylene panels (PU). With reduced dimensions and very light weight, is build under IP-67 protection. Under the same case, user will find: Local Indicator, Analyzer, Transmitter and Controller of ease operation.
This can cause the measurement to be skewed. The OMEGA Turbidity Meter LED light source emits at a range close to infrared. In this range absorption is minimized, and turbidity measurements are more accurate.

4. Turbidity Measurement Principles (cont.) Vial Transmitted 90° Light Light Emitting near “ IR” Reflected Light @ 90° Detector As detection involves the difference between the light reaching the vial and transmitted by the sample placed at the cuvette, it is convenient to minimize the effects that diminish the light intensity transmitted, among those the most important, it is the absorption caused by the samples color.

9. Lens and Bubble Trap Cleaning Sensor Unit Lens and Bubble Trapper Cleaning LENS CLEANING OF SENSOR UNIT Remove the Sensor/Turbidity Detector (5) by turning it clockwise (45degrees) and pull it up. Using a soft sponge and neutral soap, wash the Led and the photocell Lenses. After this, dry it using a soft Absorbent paper, a type that will not leave residues.

9. Bubble Trap Cleaning (cont.) Remove the Bubble Trapper by pulling it up. Bubble Trapper Body Totally remove the Bubble Trapper from the body. Wash it using neutral soap and a small brush, using circular movements, clean the openings. Rinse using plenty of water and dry it using a soft absorbent paper, a type that will not leave residues.
10. Calibration Information 1) Prepare the calibration standards need for your application (see page 14 for instructions on how to formulate standards). 2) Close the process Sample Inlet. 3) Un-thread the Drainage Lid, in order to remove the sample located inside the Bubble Trapper. 4) Remove the Sensor Unit from the Bubble Trapper and insert the calibration cup, as shown below.
11. Turbidity Standard Instructions on how to prepare Calibration Solutions 1. Standard Zero In order to obtain a turbidity close to Zero, use a good quality deionized or distilled water and filter it twice in a roll, using a 0.2 µm filter and teorically you will obtain a water with 0.12NTU, that can be considered Zero (Blank).
12. Equipment Operation Set Up Procedures The equipment offers a non-volatil memory (E2PROM), in order to store operations functions (resolution, reading, Calibration and more). Even when turned off from power, all functions chosen during set up will remain stored. Before starting any work with the equipment, it is recommended to verify the SET UP parameters, to certify that you have chosen the correct options for the operation .
