*NOTE: These are default ranges; settings are adjustable to meet site specifications.
Stabilization basis 3 consecutive readings of selected parameters (one or more of above 5) within above limits, at time interval selected, from 1 to 9 minutes. For example, if 2 minutes is selected, then stabilization would be signaled when 3 consecutive 2-minute intervals showed in-range readings at the end of each interval, requiring 6 minutes.

Elapsed time since PurgeScan initiated shows at the bottom of the screen.

Stabilization of purge water quality is signaled visually and audibly when 3 consecutive readings of selected quality parameters (one or more of above 5) fall within the selected ranges. The time interval between readings is selected from 1 to 9 minutes. For example, if 2 minutes is selected as the interval between stabilization readings , then stabilization would be signaled when 3 consecutive 2-minute intervals showed in-range readings at the end of each interval, requiring 6 total minutes of stabilized purge water quality. The elapsed time since PurgeScan was initiated is displayed at the bottom of the screen.

Full data sets are stored at time 0, every 5 minutes, and the 3 consecutive readings which satisfy the stabilization criteria.

 
pH 4.0 storage solution:
The system shall include a plastic calibration/storage cup and a provision for storing the sonde, with all sensors installed, in water, alcohol or KCl storage solution.
