The user will log on to the cutting-edge hand-held pda. Throughout the day, triggered by predetermined time mechanisms and locations, the Dacol system will inform the user to carry out an audit. Moving to that individual scan point, the easy to use menu system will request and record the data specific to that location at that time e.g. what temperature is the pool water? Each time the pda is docked with your computer, the information is downloaded. The unique Dacol desktop software enables in depth reporting, comprehensive historical analysis and long term storage. The number, frequency, type and complexity of each audit is designed by you to fit in with your existing systems.
