GF 4630 Chlorine Analyzer System (Gen II)

The GF 4630 Chlorine Analyzer System (Gen II) is an enhanced version of the 4630 chlorine analyzer that comes with a new safety feature known as Chemical Guard. This helps prevent unnecessary dosing of chlorine when the flow is stopped. Chemical Guard can also be used to disable/interrupt reagent addition when the situation calls for it. This is accomplished with the addition of a built-in flow switch and Chemical Guard software.

The 4630 Chlorine Analyzer System is an integrated, all-in-one Chlorine Panel System designed to measure Free Chlorine in drinking water and clean, fresh water treatment applications.

Key Benefits
  • Complete Chlorine Analyzer System allows quick setup and easy installation. Connect to a water source and apply DC power (12-32VDC).
  • Highly accurate and reliable measurement: Built-in pressure regulator maintains constant flow and pressure to the sensor regardless of the inlet pressure.
  • Great stability: Chemical Guard software (safely controls chemical dosing pumps)
  • Designed to meet the EPA guidelines for measuring chlorine levels in distribution networks (Free Chlorine only)
  • Flexibility: The system now offers four each 4 to 20 mA outputs, 3-9950.393-3, two mechanical relays and four binary input module with the option to add Modbus communication module 3-9950.395-M.
  • Suitable applications are drinking water treatment, process water, municipal and industrial water distribution, pools and spas.
