Hanna Instruments BL 983313-1 Mini pH Controller

Hanna Instruments BL 983313-1 Mini pH Controller

This Hanna Instruments mini controller has been specially designed for water conditioning and cultivation applications. Its compact design allows it to be installed in confined spaces, or even in close proximity to the tank or drum containing chemicals. This device allows automatic monitoring of installations previously monitored manually.

EC measurements are displayed on the screen, and the multicolor LED continuously indicates whether the mini controller is in measurement, dosing, or alarm mode. The BL 983313 measures in the range of 0 to 1999 µS/cm.

The user can select automatic or manual dosing mode using a switch located on the front panel. Manual monitoring is particularly useful during maintenance operations, as it allows operators to activate or deactivate the dosing relay as needed. The overtime monitoring system alerts the user when the relay is activated for too long, thus preventing overdosing.
