oil in water monitor TD-4100

 applications.Low Maintenance. There are no tubes, pumps or valves to replace. The system's one moving part has a life expectancy  of. greater than 5 years. Routine maintenance involves changing a lamp twice a year and an air filter periodicallyDirect, Continuous Monitoring. The TD-4100 monitors a flowing water stream continuously. No chemicals, no pre-treatment and no manual manipulation of the sample are required to monitor aromatic hydrocarbons.Accurate. The TD-4100 directly measures aromatic hydrocarbons in water with accuracies that consistently correlate to regulated laboratory methods. Sensitive. BTEX, gasoline, diesel, jet fuel, crude oil, aromatic solvents and refined petroleum products containing   aromatics are detected by the TD-4100 from low ppb (ug/L) to high ppm (mg/L). For example, the TD-4100 can detect 5 ppb of gasoline or diesel fuel in water free of interfering compounds.Selective. The TD-4100 continuously measures the fluorescence of aromatic hydrocarbon compounds in water. Fluorescence occurs when a molecule absorbs light energy of one specific wavelength and emits light energy of a longer wavelength. Fluorescent compounds each have a unique signature, and these compounds can be displayed as an actual concentration.Effective Monitoring in Dirty Water.Monitoring fluorescence makes the TD-4100 resistant to interferences by turbid or dirty water which impact on-line UV or IR light scatter instruments. Most substances absorb light, but very few fluoresce; if a substance does not fluoresce at specific wavelengths for the monitored aromatic hydrocarbon, it will not interfere.Operator Friendly. The TD-4100 is designed for easy operation. Simple on-board software controls alarms, 4-20 mA output, diagnostics and calibration.
