One Bottle Biochemical Oxygen Demand (BOD5) Analyzer LH-BOD301
This instrument is manufactured in accordance with ISO 9408-1999 and complies with the reaction procedures specified in the national standard HJ 505-2009 ("Water quality—Determination of the biochemical oxygen demand after 5 days (BOD5)—Dilution and seeding method"). It utilizes a mercury-free differential pressure method, ensuring freedom from mercury contamination and delivering accurate, reliable data.
1, The test cap operates independently and supports configurable parameters such as test durations (1–30 days) and constant-temperature equilibration times (1–10 hours); it stores up to 100 historical records and automatically overwrites the oldest data.
2, Measurement range of 0–4000 mg/L with support for 8 sampling range options; provides direct concentration readings (BOD values displayed without conversion), with hardware upgrades ensuring higher accuracy for low-range measurements.
3, The test cap functions as a miniature control unit featuring a built-in CR-P2 lithium battery and a large 1.5-inch OLED screen for viewing test data and curves; temporary power interruptions to the main unit do not affect the test process.
4, Compact and portable design with integrated electromagnetic stirring; indicator lights provide a clear view of power and stirring status, ensuring sample homogeneity during the experiment for more accurate results.
5, Works with a dedicated mini-program to support real-time and historical data viewing, multi-curve comparative analysis, multi-site data logging, and tiered account management; enables full digital integration from data collection to analytical decision-making, enhancing operational and management efficiency.
6, Complies with the reaction process defined in the national standard HJ505-2009 and is manufactured based on ISO9408-1999; utilizes the mercury-free differential pressure method, ensuring no mercury pollution, reliable data accuracy, and flexible testing schedules.
7, Comes standard with a complete set of experimental consumables and accessories—including culture bottle caps, BOD culture bottles, bottle racks, stir bars, reagent cups, funnels, tweezers, precision pH test strips, and a BOD consumables kit—allowing for immediate operation.
