Hach 5500 sc 水质光度计和色度计

"Lower Maintenance, Less Downtime. The 5500 sc Silica Analyzer requires only two liters of reagent for the analyzer to perform unattended for up to 90 days; twice as long as the Series 5000. The industry's only pressurized reagent delivery system eliminates the frequent maintenance associated with pumps. Predictive diagnostic tools, including Hach's proprietary Prognosis technology, warning LEDs, and high-visibility notification screens let you avoid unplanned downtime. No more dripping reagents on the instrument, the floor, or your clothing while fumbling with tubes and straws. Simply match the color-coded cap to the sealed reagent bottle and twist gently. Grab Sample In and Grab Sample Out features allow quick analysis of a grab sample poured into the analyzer, and facilitate taking a sample out of the analyzer to verify in a lab test."
