ORP Mini Controller


ORP Mini Controller for panel mounting, specially designed for swimming pools and spas. Thanks to its compact size, can be installed in small spaces. BL is the ideal solution for those who have always checked ORP manually. Thanks to the automatic dosing, this mini controller will significantly reduce maintenance time. Can be used with any ORP electrode with standard BNC connector. The instrument measures ORP in the 0 to 1000 mV range and shows the readings on the large display. The status LED continuously indicates if the controller is in measurement, dosing or alarm mode is also provided with a relay for selecting the dosing direction, oxidizing or reducing.You can also choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because it permits you to enable or disable the dosing relay according to your need.The overtime control system advises you when the relay is active for too long, helping to prevent over-dosage.
