Response time Sensor pulse repeat frequency: 0,001 seconds, averaged over 1 second. Updated
every second in the analyzer. Moving average can be set between 1‐60 seconds.
Measurement absolute
error
In tap water within calibrated temperature range: 3 g/l.
In slurry: average error is 9‐15 g/l, due to changing morphology of particles,
inhomogeneous state of slurry and temperature sensitivity of dissolved solids.
Measurement relative
error
15 g/l in the range 1000‐2500 g/l is 1%
Ageing About 1% per year. Perform a water calibration each 3 months.
