Designed to bring simplicity to pH testing during the any process, the Hanna Instruments Checker Plus pH Tester is designed for direct measurement.

Your measurements require detailed attention; so should your electrode. The HI98100 features a replaceable electrode that is ideal for general pH measurements. A replaceable electrode extends the life of your digital pH tester. The supplied HI1271 pH electrode is 103 mm long and tapers to an 8 mm diameter at the sensing end to easily fit into test tubes, vials, and other containers with a small opening. We believe that buying a tester should be simple. Your HI98100 Checker Plus pH tester is equipped with everything you need for successful testing right out of the box.

Hanna Instruments Checker pH Tester with Replaceable Electrode Reviews

Different meter: The picture of the Hanna pH Checker on your website is not the one I received. I believe it is a picture of their previous model. Also, it would not hold a calibration of 7.1 pH ; the "reading" varied. The meter received would only read to 0.1 whereas the meter in the picture would read 0.01(like my old meter which I use to make wine and need the 0.01 level).
But I think you for accepting the return of the new meter.
Your service policy was great and I would recommend your company to others.
