The Hanna Instruments BL120-201 Pool Controller Injector is a precision-engineered dosing component designed for use with the Hanna BL10x, BL12x, and BL13x series pool and spa controllers.

This injector allows accurate and consistent delivery of chemical reagents — such as chlorine or acid — directly into the return line of a swimming pool or spa system. It connects to the outlet of the peristaltic dosing pump via compression fittings and is threaded (½″) for secure installation into an injector saddle.
