BOD Self-check MeasurementRespiration/Biogas Determination with OxiTop ® and OxiTop ® ControlOxiTop ® & OxiTop ® Control• Undiluted samples• AutoTemp function for delayed startof cold samples• Secure storage of measured valuesMercury-free measurementBiochemical oxygen demand (BOD) determination is one ofthe most important parameters in water resource management,and is used to evaluate the impact of biodegradablesubstances in waters and wastewater. With its OxiTop ®systems, WTW offers a unique, modular and mercury-freeinstrument system, suitable not only for BOD determination,but also for measuring biodegradability and depletion.The advantages of OxiTop ® and OxiTop ® Control includesimple operation and improved controls with measuring ofup to 400 000 mg/l BOD (with OxiTop ® Control OC 110).As the measured pressure is automatically converted, thevalues can be directly read as mg/l BOD.Application rangeOxiTop ® OxiTop ® Control OC 100 OxiTop ® Control OC 110Application BOD routine BOD routine,BOD standardBOD routine, standard andBOD special, respiration/dilution,soil respiration, biodegradability,biogas determinationBOD range 0 – 4.000 mg/l 0 – 4.000 mg/l 0 – 400,000 mg/lMeasured value 5 days 0.5 hours – 99 days 0.5 hours – 99 daysmemoryPressure mode — — Pressure p 500 – 1.350 hPaSample volume Fixed Fixed Definable82For information visit www.WTW.com for a customer care center near you or inside US: call WTW 800 645 5999.
