супер быстрая доставка. прибор качественный, предварительно откалиброван. отклонения от лабораторного несущественно мизерные. благодарю. рекомендую.

No battery included forgot this part since I ordered it, luckily I had some laying in a cupboard.. yee. After a quick calibration ran a small test with tap water and bottled water, working quite accurately, so I'm happy with the purchase! Recommend!
Works great and is precalibrated. I tested with local tap water and the pH came out close to what I expected - 7.3. It does not include the LR44 batteries and needs 2 of them so make sure to order some or have 2 ready. Highly recommended.
received still need to use by me
good👍👍👍
arrived without battery can't show if it work untill I found the battery
works well thank you
HELLO The product had no dust, no screwdriver to cover (calibration) the electrode.
