I found this on a listing that has the item for sale
https://www.ebay.com/itm/Hanna-Inst...036107?hash=item33d55df2cb:g:1mkAAOSwaWhZzD0j
:The HI98103 Checker pH tester has been designed with many advanced features while maintaining the look and feel of the original Checker. The redesigned Checker now offers automatic calibration to one or two points, automatic buffer recognition, calibrated buffer tags, stability indicator, low battery indicator, and selectable automatic shut off.
Does this mean it no longer needs calibration fluids? Doesnt seem to come with any in this listing?
Thanks for all the replies everyone, i really apopreciate all the info and will be looking into all of them.
