GF Signet 4630 Chlorine Analyzer System

The GF Signet 4630 chlorine analyzer system is an integrated all-in-one system designed to measure free chlorine. The 3-4630 chlorine panel with pH sensor is used to accurately calculate free chlorine in applications that have varying pH values (±0.20 pH units).

The advanced 9950-3 Chlorine Controller includes a new feature called the "Chemical Guard" relay control. Because free chlorine concentration is pH dependent, the Chemical Guard feature interrupts/disables the relay that is assigned to the oxidant chemical (such as sodium hydrochloride) until the pH of the application is corrected. The 4630 series also comes with a flow switch that will disable the mechanical relays to the dosing pumps when the system is off or flow is interrupted to the flow cell.

The unique integrated clear flow cell accommodates the free chlorine and pH electrode, 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 the 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 4630 chlorine analyzer system's panel design allows quick and easy installation and is supplied with four 4 to 20 mA outputs, flow switch with relay interrupt, four binary inputs and two mechanical relays.

The 3-4630 chlorine system can be used for reporting chlorine residuals in accordance with EPA Method 334.0.
