Georg Fischer 4632 Specifications

Signet 4632 Chlorine Dioxide Analyzer System

T

Features

• Reagent free measuring

• Complete panel system allows for quick and
easy installation

• Built-in flow regulator maintains constant flow
and pressure to the sensors regardless of inlet
pressure

• Pre-wired panel includes a 100/240 VAC
power supply, two 4 to 20 mA outputs and two
mechanical relays

The Signet 4632 Chlorine Dioxide Analyzer System is an
integrated all-in-one system designed to measure
Chlorine dioxide residual up to 2 ppm/mg/l.

The unique integrated clear flow cell combines sensors,
flow regulator, filter and variable area flow indicator
in one compact unit. An integrated flow regulator with
removable filter accepts inlet pressures of 1 to 8 bar
(15 to 120 psi), while maintaining constant flow and
minimal pressure to the sensors.

Water flows vertically into sensor tip eliminating bubble
entrapment. The flow cell is designed to maintain a
minimum amount of water to ensure sensors stay
submerged, even when the system and flow is
turned off.

The Signet 4630 Chlorine Analyzer System allows quick
setup and easy installation and is supplied with a
100-240 VAC power supply, two 4 to 20 mA outputs and
two dry contact mechanical relays.
