MEASURED RANGE*: 50 to 2,000,000 µS/cm (see chart)

ACCURACY: ± 1.0% of reading

REPEATABILITY: ± 0.25% of reading

STABILITY: 0.25% of output range/month, non-cumulative

AMBIENT TEMPERATURE COEFFICIENT: ± 0.2% of FS/°C

COMPATIBLE RTD: 100

Ω with Automatic Recognition

TEMPERATURE SLOPE ADJUSTMENT: 0-5%/° C

Sodium Hydroxide: 0 to 15%
Hydrochloric Acid: 0 to 16%
Sulfuric Acid: 0 to 25% and 96 to 99.7%

LOOP ACCURACY: With a standard Model 228 or 225

sensor with 20' cable, laboratory accuracy at 25°C can
be as good as ± 2% of reading and ± 50 µS/cm.

To achieve optimum performance, standardize the sen-

sor in the process at the conductivity and temperature
of interest.  

RTD ACCURACY: Utilizing a perfect 100 Ohm RTD after

1 point temperature standardiztion, temperature read-
ing can be as good as ± 0.5°C.

NOTE:

Values shown are for 25°C conductivity with a temperature slope of 2% per degree C. The maximum range
value will be lower for solutions with a higher temperature slope. Minimum conductivity depends on sensor.
