Different results using speedstir...

[Rogue959]

Is this normal ? I assume the better mixing is more accurate .

FC seems to be lower than expected by around 2ppm
TA higher than expected 20ppm
CH lower than expected 75ppm

I'm aware that the CH test is improved with the use of the Speed Stir, but I'd not heard anyone mention the others.

I agree that better mixing tends to give better results.

I just got my speedstir today and just tested my FC. about 1 PPM lower than when I manual stir.

The Speedstir dissolves the powder much better than hand swirling.

Thanks all

The big question is just. Is the kit calibrated with manual stirring in mind or the perfect mix in mind?

The kit gives the most accurate results when everything is fully dissolved. Using a SpeedStir helps to ensure this - and makes testing easier, ensuring more consistent results.

Samplesizer adds even more consistency.
