I got my pH tester ahead of schedule. I've learned how to calibrate it. I'll be back for a ppm meter soon.

Product, a hand-held pH meter, was shipped in 2 days and arrived 4 days after my ordering. Packaging was adequate, in excellent shape and appropriate. I was kept informed of my order’s status and it’s ETA. It arrived 12 hours early. Thank you again.

Fast response

Great Service, kept me updated on my order status, shipment date and delivery!! Will absolutely continue to do business with this company and you will want to as well!!!

Everything that I needed Hannah instruments was there to help
