The bottle was exactly as expected, although I was unprepared to use it.The only cup I had at the time was from the cupboard and that use most of the solution just to test once. Since then, I’ve decided to order small paper "medicine" cups which will require far less solution.BTW after only having my pen for a couple months, it was pretty far off so I really needed the solution.
I picked up another brand from GH and it was not even close to stated reference after testing with multiple meters.This solution was right on the money and exactly what I needed to check/calibrate my Bluelab EC meter. (Also tested with multiple meters with positive results).Item shipped fast and in great condition.Would definitely buy again and recommend.
Man shows how off the meter is right out the box. Every meter is perfect now.
Keeps my ppm pen calibrated without question...
Excellent product and excellent seller
Over priced but exactly what you need
Someone decided to use all the tape.
Works as expected.
Money well spent!
