水中揮發性脂肪酸&鹼度監測儀 EZ7250 Volatile Fatty Acids (VFA) & Alkalinity Analyzer
產品編號：EZ7250.XXXXXXXX
Online, automatic monitoring of critical process parameters and process efficiency in anaerobic digesters
線上、自動監測厭氧消化槽的關鍵參數和過程效率
創新技術監測厭氧消化過程
A new control alternative for anaerobic digestion
Due to the expensive or time-consuming character of most analysis methods for anaerobic processes, industrial digesters are usually not adequately monitored. Developed specifically for monitoring anaerobic digesters, the EZ7200 Series bring the possibility of implementing new control alternatives to typical operating problems in mid to large scale digesters.
EZ7200 系列專門為監測厭氧消化槽而設計，為中大型消化槽的典型操作問題帶來新解決方案。
線上自動監測關鍵參數
Critical parameter monitoring, online and automatic
Anaerobic digesters require monitoring of a specific set of critical parameters in order to obtain optimal production efficiency, compliance and biogas yield. The primary parameter is volatile fatty acids (VFAs), representing the metabolic condition of the anaerobic digester and responding quickly to stress induced changes, combined with alkalinity.
厭氧消化槽需要監測特定的關鍵參數以獲得最佳化的生產效率、合規性和沼氣產量。主要參數是揮發性脂肪酸 (VFA)，它代表厭氧消化槽的代謝狀態，反應壓力變化，同時也與鹼度相關。
The EZ7200 Series are easy-to-operate online titrators using a unique and robust method for measuring the critical process parameters in one single run, enabling insight as well as full control over the anaerobic process.
