Description

The Sper Scientific 870020 Industrial Online Sodium Analyzer continuously monitors sodium ions in water and process solutions.

Its low-concentration measurement capability supports water chemistry monitoring in power generation, water treatment and industrial processing.

The analyzer combines a sodium measuring electrode with an automatic sample flow system and alkalization system. An English-language display presents readings, while isolated analog outputs and RS485 communication connect the analyzer to monitoring equipment. Historical measurements can be reviewed as a trend curve.

Features

  • Continuous online sodium monitoring
  • Automatic temperature compensation
  • Automatic sample flow and pressure compensation
  • Adjustable high and low alarm thresholds
  • Approximately one month of historical data and a 200-message event log
  • One to six sample channels available by configuration
