Hanna Instruments BL-982411-1 Mini pH Controller

The BL 982411 is a panel-mount mini ORP controller specifically designed for pools and spas. Thanks to its compact size, the BL 982411 can be installed in tight spaces. It is the ideal solution for those who have traditionally manually checked ORP. Thanks to its automatic dosing, this mini controller significantly reduces maintenance time.

The BL 982411 can be used with any ORP electrode with a standard BNC connector. The instrument measures ORP in the range of 0 to 1000 mV and displays the values ​​on its large display. The status LED continuously indicates whether the controller is in measurement, dosing, or alarm mode. The BL 982411 is also equipped with a relay for selecting the dosing direction (oxidizing or reducing).

You can also select automatic or manual dosing mode using a switch on the front panel. Manual control is particularly useful during maintenance operations, as it allows you to activate or deactivate the dosing relay as needed. The activation time monitoring system warns you when the relay is activated for too long, thus preventing overdosing.
