Average Accuracy: ± 1.5%
Method: Temperature compensated electronic conductivity
meter with adjustable alarm limits.
Temperature compensated conductivity display with
automatically set alarm windows ±0.5 mS/cm around calculated
conductivity*. User can adjust an additional ±0.5 mS/cm within
this range.
Temperature compensated conductivity display with
automatically set alarm windows ±0.5 mS/cm around calculated
conductivity*, limited to ±0.4 mEq/L @ 24 mEq/L bicarbonate or
less.
With alarm window set at ±0.5 mS/cm:
User can move alarm window up or down an additional:
±0.2 mS/cm @ 40 mEq/L
±0.1 mS/cm @ 35 mEq/L
no adjustment @ 29 mEq/L
*Conductivity is based on the concentrates' compositional data
entered in the Dialysate screen at the standard temperature of
25 C.
10.0 to 17.0 mS/cm. At 25 °C. Alarm limits will not go below 12.5
or above 16.0 mS/cm.
35 to 39 °C Accuracy: ± 0.3 °C (measuring accuracy under
calibration conditions for a dialysate flow of 500 ml/min)
(selectable in 0.1 °C steps)
Range 35 to 39 °C with alarm limit window automatically
adjusted to 2 °C above and below set point. Alarm window will
not go below 30° or above 41 °C. Heater 1.3 kW, electronically
controlled.
