Calibration: Direct Input of Offset and Slope
Model SU800 SingleSense™ Single-Use pH Sensor
Figure 5. Direct input of offset and slope
1. Reference the data on the
calibration tag.
2. Take the
Factory Offset
and
Span/slope (mV)
information and
input it into the process
instrumentation.
Note:
The pH value should read within
0.05 pH units of the values on the
calibration tag, correctly reflecting the
buffer storage chamber pH.
See next slide to perform a 1-point
standardization.

2.0 Startup, Calibration, and Operation
The
Span/slope (mV)
is the sensor’s mV to one pH
units at a given temperature or the percentage of
the theoretical value of the sensor’s millivolts to pH
units at a given temperature.
The
Factory Offset
is the sensor’s
offset (mV at pH 7) when measured
at the factory before shipping.
