I've got a 3 month old Hanna testing pen. This is the top of the line one that does PH/ EC/ TDS/ Temp. Includes a bunch of calibration, storage and rinse solutions to keep it running top notch for years to come.
Spent over $200 with all the calibration solutions 3 months ago. Freshly calibrated and always kept with storage solution on the tip.
Asking $125 to your door Priority Mail!
