Series A790 Amperometric Titrator

The Series A790 Amperometric Titrator from Wallace & Tiernan® systems is ideal for the precise measurement of chlorine residuals, including very low residuals, for the calibration of on-line analytical equipment.

The Amperometric Titrator is also used in large swimming pools and food plants, bottling plants and research and development facilities to calibrate automatic residual-recording and control equipment. It is easy to understand and operate which encourages frequent testing to ensure precise measurement and control of chlorine residuals.
The unit is suitable for the residual tests in Standard Methods and ASTM METHOD D-1253.
