  • Page 8: Overview

    < 1. Overview > OVERVIEW Model ST401G is a compact sampling system which can be used with the pH converter system and the model FC400G non-reagent type free available chlorine analyzer. The measurement can be started after only simple installation because the ST401G is provided with a pressure-reducing valve and ball valve, and shipped with customer ordered devices.

  • Page 9: System Configuration

    Model ST401G refers only to a sampling system and does not include a free available chlorine analyzer and/or a pH meter(sensor,holder,converter and ultrasonic oscillator). (Instrument should be purchased separately.) Note that the ST401G Sampling System accepts the following models of note 1 or note 2 only, and depending on system configuration. Note 1: Non-reagent type free available chlorine analyzer (refer to GS 12F5A1-E) When ordering, option code “/ST”...
