The MG/L 5 controller's modular design accepts up to seven analyzer input modules expanding its control capability to include three fully programmable milliamp (mA) input modules.  The backlit display easily shows measured values, limit values and graphical trend lines.  Critical control inputs are easily calibrated with factory supplied liquid standards, allowing for easy and accurate calibration verification by anyone.  The electronics are housed in a NEMA 4x enclosure and the controller is designed to comply with UL 61010, CE and CSA certifications. The ChemWeb server allows for easy communication with the controller via the Internet and / or local Ethernet.

The MG/L 5 controller incorporates numerous technical advances in one new pool water control instrument: 

• numerous controller communication options,
  controller display data trending of control parameters for up to seven days, 

• on site calibration of all critical inputs, 

• continuous hydro-mechanical cleaning of the free available chlorine sensor

• a fully integrated flowcell design that includes precise sample flow regulation past the probes for increased measurement accuracy.
