Accuracy Note
:
The Q46C2 is designed to allow measurements over a broad conductivity range using sensors with
either 0.05K or 0.5K cell constants. However, extending the measurements made with various cell
constants can result in some non-linearity at the high end of operating ranges. This can reduce
accuracy from 0.1% to 1-2% in some cases. When high accuracy is critical, the following provides
a list of the preferred cell constant to be used for various operating ranges in order to maintain the
highest accuracy.
0.05K Sensor
– Use for all resistivity ranges (20 M
or 200 K
)
0.05K Sensor
– Use for 0-2.000 or 0-20.00 uS ranges.
0.5K Sensor
– Use for 0-20.00, 0-200.0, 0-2000 uS ranges.
Equipment bearing this marking may not be discarded by traditional methods in the
European community after August 12 2005 per EU Directive 2002/96/EC. End users
must return old equipment to the manufacturer for proper disposal.
