Photometer System

Photometric analysis and measurement for water-treatment applications

Introduction

The SEKO Photometer System is a professional instrument for measuring chlorine, based on sampling with the photometric method (DPD).

Real-time measurement of parameters ensures the highest accuracy in professional water-treatment applications.

The Photometer System allows users to monitor up to six parameters: three parameters with the photometric sampling method and three parameters using external probes.
