HI181 Compact Magnetic Mini-Stirrers with Electrode Holder

Magnetic stirrers are important accessories found in any testing environment. A magnetic stirrer will ensure that your sample is completely mixed through resulting in greater stability and more accurate measurements. The movement will also increase the response time of your electrode in solution so you can spend less time testing.

Electrode Holder

Built-In Electrode Holder

The adjustable electrode arm of the HI181 mini-stirrers hold up to three 12 mm diameter electrodes for convenient all-in-one measurements of a single sample. For measurements that require temperature compensation, a Hanna temperature probe can be placed in the electrode holder to obtain accurately compensated readings.



This stirrer incorporates electronic controls that allow the user to regulate the speed with greater precision. The internal Speedsafe™ mechanism will ensure that the maximum speed is never exceeded for safe operation.
