The Hanna Instruments BL120‑202 Aspiration & Dispensing Tubing is a dedicated tubing kit designed to complement the BL10x, BL12x and BL13x swimming pool and spa controller families. This kit supports accurate reagent delivery by supplying the correct tubing for both aspiration (suction from the reagent tank to the dosing pump) and dispensing (from the dosing pump to the injector).

By using the correct tubing set, you ensure optimal chemical dosing performance, reduce the risk of tubing mismatch, and maintain reliable flow throughout the dosing line. The BL120‑202 tubing is engineered for compatibility with Hanna’s peristaltic pumps and injector assemblies.

Key Features:

• Supplied length: Approx. 10 m (combination of aspiration + dispensing tubing) for full system installation.
• Designed specifically for Hanna pool controller systems (BL10x / BL12x / BL13x series).
• Includes both flexible suction tubing (for drawing reagent) and rigid or semi‑rigid dispensing tubing (for delivering reagent to the injection point).
• Chemically compatible materials suited for acid/chlorine dosing applications.
• Helps maintain system integrity, correct installation and reliable dosing.

Typical Applications:

• Installing or replacing tubing in pool/spa automation systems operated by Hanna controllers.
• Ensuring full system maintenance when servicing the dosing pump or changing reagent sets.
• Use in commercial or residential pool environments where accurate chemical control is essential.
