Reliable Fluoride Measurement in Complex Water Matrices 精確穩定可靠監測複雜水基質中的氟化物濃度

Fluoride measurement in wastewater and industrial process water can be distorted by matrix effects from ions such as calcium and aluminum. The EZ3508sc uses a standard addition method to compensate for these interferences, delivering accurate, repeatable fluoride results while minimizing reagent consumption.
廢污水和工業製程用水中的氟化物測量會受到鈣、鋁等離子基質效應的影響。 EZ3508sc 以標準添加法補償這些干擾，大幅減少試劑消耗，同時提供準確、可重複的氟化物監測數據。

Designed for reliable operation, gel-filled ISE electrodes eliminate electrolyte refilling and automated cleaning and calibration reduce hands-on maintenance. Digital communication protocols integrate the analyzer into your network for immediate access to results, diagnostics and status.
