Introduction: The SH series intelligent BOD tester conforms to the national standard "HJ 505-2009 5-Day Cultivation Method", which can simulate the biological degradation process of organic matter in nature, and measure the BOD value in water using the principle of mercury-free pressure difference method. The whole machine is fully intelligently designed, designed and manufactured with advanced R&D technology, and the experiment process does not require the experimental personnel to be on duty, the operation is simple, safe and reliable. Measuring principle: The biochemical oxygen demand refers to the amount of dissolved oxygen consumed in the biochemical process of organic matter in the biochemical process of the biological decomposition of some oxidizable substances in the water by microorganisms for the set time of incubating the water sample at 20°C±1°C. According to the national standard "HJ 505-2009 5-Day Cultivation Method", our company has designed and developed the SH series BOD tester. Features: 1. This equipment combined with a constant temperature incubator can simulate the biodegradation process of organic matter in nature 2. Humanized design, simple operation and convenient use 3. Use mercury-free differential pressure method to measure BOD in water, fully intelligent operation, safe and reliable 4. No need to be on duty, historical data can be queried after the experiment 5. Imported pressure sensor components are used to effectively ensure the accuracy of data 6. Color LCD display, each culture flask works independently and is controlled separately Technical Parameters: Model: SH-812 type Range: 0-4000mg/L segment (0-20, 0-40, 0-80, 0-160, 0-320, 0-800, 0-2000, 0-4000) Number of samples: 12/batch Resolution: 0.1mg/L Accuracy: ±8% Test period: 1-30 days Range selection: 8 groups Data display: direct reading Backlight: adjustable Battery life: 1 year Temperature display: display Data recording: 2 hours/time Measuring principle: mercury-free differential pressure method Culture temperature: 20℃±1℃ Stirring speed: 100-500 revolutions/min Stirring method: electromagnetic Stirring power supply: AC220V±10%/50-60HZ Rated power: 28W Instrument size: 393*343*105mm
