The  Oil and Grease Analyzer  measure the concentration of oil and grease in water samples. the solvent in the sample work to dissolve the  non-polar organic compounds, with the method of solvent extraction. The extracted compounds are concentrated and  evaporate the solvent to leave behind the concentrated oil and grease. The final results are displayed  milligrams per liter (mg/L),Measurement Range=0-12-to100-mg-l; Measurement Limit=lt-0-12-mg-l; Max. Measured Concentration=64000-mg-l,for more visit  Labtron.us
