Just received confirmation of Simpool PH order

Impressive looking piece of kit. I use a plastic carboy for my acid and it seems fine so far.

Susa, any updates on how it's working with temperature's rising?

>> updates on how it's working with temperature's rising?

we've had no real change to temps in last 3 months, steady 70's at night and 80's days, all automatic functions work well, pH is always at 7.7-7.8 as dialed on the Simpool

having dropped TA to 50, I use hardly any MA for the injections.

Mines fine too, but after a sensor change I still have to set it using manual pH testing as the dial is not calibrated anymore and doesn't seem to have a calibration screw, although there is probably one internally I'll go hunting for when the warranty has run out.
It holds my pH exactly where I set it to, which I verify using a digital pH tester.

>>.. which I verify using a digital pH tester...

uh oh... found a large variance between the TFT test kit pH value vs multiple digital testers, you *may* want to doublecheck that pH with something else..

Thanks for the advice. I do recalibrate it often and cross reference against phenol red.
