Update August 19th, 2022 --

We are currently out of the original grey Smart Stir that is included in the TF-Pro and TF-Pro Salt. For this reason, the grey Smart Stir has been temporarily removed from individual sale. We expect more Smart Stirs to be delivered in early September but do not have confirmation of an exact date. We will update this page with more information as we obtain it.

We now offer Taylor SpeedStir magnetic stirring devices as well as the Smart Stirs. The Taylor SpeedStir is a comparable device to the Smart Stir. It fits in the TF-Pro case where the Smart Stir would belong, works with all TFTestkits cylinders, and mixes tests automatically with the press of a button. 

If you prefer to receive a Taylor SpeedStir, select the corresponding option before adding a Pro kit to your cart and you will save $12 on your kit. Otherwise your Smart Stir will be shipped to you, free of charge, when it arrives.

We apologize for the inconvenience this has caused and appreciate your patience.


Blue Smart Stirs were ordered in error and are now on closeout sale. They are fully functional but there is one problem: the LED lights on the unit are tinted blue, which can interfere with testing visibility as opposed to helping. Hence, they are on steep discount! If you do not use the LED light function, they are no different from the original Smart Stir.

The Smart Stir is a magnetic stirring device that makes mixing your testing solutions totally painless. Portable with single click operation. Automatic shutoff after 4 minutes for improved battery life. Fits all industry standard pool testing and mixing tubes (25-32mm diameter), and is 100% compatible with all TFTestkits tubes, kits and tests. Includes a heavy duty 40mL mixing cylinder embossed at 5mm increments. Comes with cross shaped stir bar for peak performance and less wobbling than other stirring devices.

All other items are in stock and will ship per usual policies. If you have any questions or concerns, please reach out via email at tftestkits@gmail.com. Please check your email inboxes and spam folders for updates from our Endicia shipping software: no-reply@endicia.com.
