Hanna Instruments Spare Magnetic Stir Bar for PCA Series Analyzers (Pack of 2) (HI70486)

Hanna Instruments Spare Magnetic Stir Bar for PCA Series Analyzers (Pack of 2)

The HI70486 is a genuine Hanna Instruments replacement magnetic stir bar designed for use inside the measuring cell of the PCA Series process analyzers. It ensures continuous, uniform sample mixing during chlorine, pH, ORP, and temperature measurements, which is essential for accurate and repeatable readings. Each pack contains two stir bars so you always have a ready spare on hand.

Compatibility

This stir bar is engineered specifically for the Hanna Instruments PCA Series process analyzers. It is not intended for use with other Hanna stirrer or titrator models.

Why genuine matters

Using an original Hanna Instruments stir bar ensures the precise dimensions and magnetic coupling strength required by the PCA measuring cell. Substitute bars may not spin reliably at the motor’s drive frequency, leading to inconsistent mixing and unreliable water-quality readings — a critical risk in professional pool and process monitoring environments.

Installation & maintenance

Replacement is straightforward: open the measuring cell, remove the worn stir bar, and drop in the new one. Routine inspection and timely replacement of the stir bar help maintain measurement accuracy and extend the service life of the stirrer motor. Keeping a spare pack of HI70486 on site minimises instrument downtime.
