水中生化需氧量分析儀 BODTrak™II
產品編號：
Hach BODTrak II 生化需氧量分析儀採用壓差法BOD檢測原理，模擬自然界有機物的生物降解過程，測試瓶上方空氣中的氧氣不斷補充水中消耗的溶解氧，有機物降解過程中產生的 CO2 被密封蓋中的氫氧化鉀吸收，壓力傳感器隨時監測採樣測試瓶中氧氣壓力的變化。
Simplify BOD analysis with the BODTrak™II Respirometric BOD Apparatus. Results comparable to the dilution method can be achieved in only two to three days. Use these results for process control or as a complement to the dilution method (not approved by USEPA for NPDES reporting purposes). The BODTrak II is a re-engineered version of the original Hach BODTrak. Improvements to the old system include greaseless bottle seals, a larger graphical display, improved stirring and temperature control, a smaller footprint, improved procedures with expanded options, an auto-switching power supply, and bottle fences to prevent tipping of bottles.
Decrease total test time 節省總測試時間
Faster than Dilution Method 比稀釋法更快
BOD results that are easy to monitor 容易監測BOD數據
Standalone operation 獨立操作
DO probes and titrations are eliminated 不用DO電極和滴定

Decrease total test time
The Hach BODTrak II Apparatus is easy to set up and allows for quick sample preparation for BOD (Biochemical Oxygen Demand) analysis. Simply pour a measured sample of wastewater and nutrient buffer into each of six BODTrak II bottles. Connect the bottles to the instrument's pressure sensors, select a measurement range, and incubate. User calibration of the instrument is not necessary.
Faster than Dilution Method
Constant stirring in the bottles supplies additional oxygen to the sample and provides bacteria with greater exposure to food. This results in more rapid respiration and consumption of oxygen.
BOD results that are easy to monitor
The BODTrak II Apparatus has a large graphic display that continuously updates results. View the results at any time during the test. The instrument plots a curve of BOD over time. To review the data in detail, simply move a cursor along the curve to display results for any stored data point.
Standalone operation
The apparatus automatically ends the test and stores teh results after the chosen test length of five, seven, or ten days. This eliminates the need to be present when the test is complete.
DO probes and titrations are eliminated
The BODTrak II Apparatus measures BOD using the respirometric method. Each sample bottle is connected to a pressure sensor in a closed system. As bacteria consume oxygen in the sample, the pressure in the bottle headspace drops. This pressure change correlates directly to BOD. By measuring pressure changes instead of dissolved oxygen levels, the need for probes and titrations is eliminated.
生化需氧量BOD是指水中的有機物被微生物生化降解時所消耗的氧氣量，是反應水中有機污染物含量的一個綜合指標，主要用於監測地表水體中有機物的污染狀況，檢測污水和廢水的有機物污染負荷，用來評估污水和廢水的可生化性。
BODTrak II 生化需氧量分析儀採用壓差法BOD檢測原理，模擬自然界有機物的生物降解過程，測試瓶上方空氣中的氧氣不斷補充水中消耗的溶解氧，有機物降解過程中產生的 CO2 被密封蓋中的氫氧化鉀吸收，壓力傳感器隨時監測採樣測試瓶中氧氣壓力的變化。在生化需氧量BOD（即對應於測試瓶中消耗的氧氣量）與氣體壓力之間建立相關性，進而精確地進行 BOD 生化需氧量檢測，測試結果在螢幕上以圖形顯示，BOD <值將以mg/L 為單位直接顯示BOD分析儀螢幕上。
- 模擬自然界微生物降解有機物的過程，更接近於真實情況
- BOD分析儀可連續讀值及圖形實時顯示測量過程變化
- 6 個獨立測量頻道
- 自動關機、自動蒐集數據
-
能在圖形中直接讀出測量結果
- 圖形中有指針指示
- 圖形顯示 BOD (生化需氧量) 的數值以及培養時間
- 與稀釋接種法相比，簡單方便
