Ambient condition
-5 to 45 °C, 5-95% relative humidity

Sample Sequencer 6 is a controller that directs several sample streams to one or more analyzers according to a programmed sequence. The duration and custom sequence of each sample are set individually, which helps obtain consistent measurements across lines and reduces reagent consumption. It can be used with different water chemistry analyzers, from sodium to silica.

  • Sample names, durations and analyzer definitions are displayed on a touchscreen.
  • Remote access is provided through a web-based interface.
  • Operates in continuous or batch mode.
  • Suitable for harsh environments from -5 to 45 °C and 5-95 percent relative humidity.

The base system supports 8 sample points and 8 analyzers; expansion packages increase this to 32 sample points. Depending on the solenoid selected, there are 12 V or 24 V outputs and 1/8 or 1/4 inch manifold options.

Sequential operation lets one analyzer measure several lines, reducing the number of instruments and reagent spending. Batch mode is preferred in applications where the analyzer must complete a full measurement cycle for each sample.

Tetra, which builds multi-line analyzer panels for power plant and process laboratories, clarifies the Sequencer's number of solenoids and analyzer interface at the start of the project, and supports in-panel piping, initial programming and later sequence changes on site.
