Дорогой друг, после установки на 30 градусов тепла, вы можете наблюдать в режиме реального времени из другого места, как дома.

Never ever buy this ph meter. It's not accurate.

[@TECHNICALASTHA]

can you share you issue , i will check again and compare with other brand

[@random.contentt.ok8]

@@TECHNICALASTHA Yess, i buy this product two days ago in Argentina. Supposedly according to the seller, it was calibrated at the factory. It obviously didn't come calibrated, and when I calibrated it with buffer 4 and 7, it never gave me a stable measurement. It varies between +/- 0.3 / 0.4. That is an imprecise measurement.
I just talked to the seller to return the product and I'm going to buy one from another brand.
