Thanks to all PM. I replied all already.

Pls note that I will bring my PH7.0 calibration fluid to test it before confirm buying. Reason why I insist to test before confirm buying is that I recently bought a test pen from a forumer who'd claimed it is working. I trusted him and bought it based on his words without testing. Upon testing at home, found that the test pen is way out of reading and impossible to be re-calibrated. This forumer then claimed 'item sold' are on 'buyer beware' basis. .

I am not blaming anyone since I did not test it before buying. However, anyone offering test pen to me, please confirmed the test pen you are selling is in good working condition to at least avoid both of us wasting time/efforts, and me hard-earned money.

Anyone knows where I can buy new test pen at reasonable prices (no need branded ones, below $40 preferably if any), kindly let me know via PM.

Thanks in advance.
