Bod oxidirect manual

BOD – biochemical oxygen demand – is an Lovibond® OxiDirect BOD measuring system records a measurement once every hour. With a measuring period of 48 hours, the unit measures and stores a BOD value once every 2 hours. If the measuring peri- • 1 instruction manual Order code: 2 44 44 The BOD system, consisting of the sample bottle and the BOD sensor, represents a closed system. In the bottle, above the sample itself, is a defined volume of air. During the BOD measurement, the bacteria in the sample consume the dissolved oxygen in the sample. This is replaced by oxygen in the bottle above the sample. The carbon dioxide. LOVIBOND, BOD Measurement, BOD Oxidirect. In addition to the BOD unit for measurement and storage of BOD levels, the Lovibond OxiDirect BOD measuring system includes sample bottles, measuring sensors, non-wearing inductive stirring system, overflow measuring flasks for metering of sample volumes, nitrification inhibitor and potassium hydroxide as an absorbent.

The unit is a 6 sample system that allows precise measurements of BOD from 1 to 28 days. Data is stored in the individual sensor heads, so it is possible to remove and reposition the bottles without losing vital data. By using different volumes of sample, the OxiDirect is capable of measuring from 0 to mg/l without the need to dilute the. operation of the Lovibond® OxiDirect BOD meter. The set contains 8 BOD CM1 test tablets that cause a defined oxygen consumption. The tablets are easy to use. Simply place a tablet in the BOD bottle, start the measurement process, read off the BOD value after 5 days, and then compare with the defined value. If this value is. BOD – biochemical oxygen demand – is an expression for the quantity of oxygen required for biological degradation of organic matter in a waste water sample.

Manual or automatic temperature compensation - BNC connector - Suitable for laboratory and on-site measurement - Electrode for oxygen included. Digital temperature control unit is adjustable to °C; Holds 2 Lovibond Oxidirect BOD Systems allowing for in situ removal of bottles, or upto 3 BOD. Respirometric BOD cell (Oxidirect), potassium hydroxide (KOH), nitrification inhibitor B (= Allyl Thiourea, or ATH) and wastewater sample.
