High-performance sodium analyser for continuous monitoring of dissolved sodium in alkaline water samples with pH ≥ 7.0.
The AMI Sodium P is a reliable analyser for continuous monitoring of dissolved sodium in steam, condensate and high-purity water with pH ≥ 7. It features reliable alkalising reagent addition with continuous pH monitoring, easy two-point calibration and an integrated grab-sample function. The analyser helps maintain water purity and protect critical equipment in power and industrial applications.
Available in 28 cm and 40 cm panel configurations, the AMI Sodium P can be used with an optional automatic sample sequencer for monitoring up to six sample streams. The 40 cm configuration also supports an optional second sample channel and automatic sodium-electrode regeneration.
Specifications
- Dissolved sodium measurement for samples with pH ≥ 7.
