Automatic Electrode Reactivation for Optimum Operation and Response Time
To maintain optimum response time, even in systems of continuous low sodium concentration, the analyzer automatically reactivates the electrode using non-hazardous chemicals.
Easy to Install, Operate, Calibrate, and Maintain
The 9245 Sodium Analyzer installs easily; it requires only power and sample connections. Clear step-by-step instructions are given by the analyzer to simplify operations such as instrument start-up, long-term stand-by, and reagent replenishment. Low ppb sodium solutions for calibration can be difficult to prepare so the 9245 analyzer is equipped with a fully automated calibration system that uses 10 ppm samples and follows a multiple step calibration cycle to accurately calibrate the analyzer. Normal maintenance consists of replenishment of the calibration solution reagents and electrolyte, typically every 100 days, and annual replacement of the reagent tube.
Adaptable to a Variety of Conditions
The analyzer is fitted with a quick-loop valve, a constant head vessel, and minimum sample flow detection to allow for variations in sample pressure, flow, and distance from the analyzer to the fresh-sample point. Grab sample can be obtained for manual calibration, accuracy verification, and measurement of one-off process samples after which, the unit returns automatically to on-line monitoring.
Lower Detection Limit of 0.01 ppb
With a detection limit of 0.01 ppb and a range of 0 to 10,000 ppb, the 9245 Sodium Analyzer is ideally suited for monitoring sodium in demineralized water, boiler feed, condensate, and all parts of the steam/water cycle.
4-20 mA Outputs and Digital Communication Options
Four sets of isolated analog outputs can be configured in 4-20 mA with three outputs assigned to sample concentration or temperature readings and the fourth reporting electrode live signal, including calibration and grab sample. Additional digital communication is available with JBUS/MODBUS or Profibus DP.
