	DESCRIPTION AND SPECIFICATIONS

1.2.3TRANSMITTER SPECIFICATIONS @ 25°C 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

Temperature Slope Adjustment: 0-5%/° C

%Concentration Ranges: Sodium Hydroxide: 0 to 15% Hydrochloric Acid: 0 to 16%

Sulfuric Acid: 0 to 25% and 96 to 99.7%

1.2.4 LOOP SPECIFICATIONS

Loop Accuracy: With a standard Model 228 or 225 sen- sor 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.

Results under real process conditions, at different tem- peratures, or using other sensors may differ from above.

RTD accuracy: Utilizing a perfect 100 Ohm RTD after 1 point temperature standardization, temperature reading can be as good as ±0.5°C.
