Review on 📊 Hydrion Chart Dispenser - 5.58 pH Range by Mohmed Burt

The product name used by Revain (seller) is less obvious than the actual name of this product. Name used by Revain: Hydrion pH 15 Foot Roll with Chart and Dispenser 5.5-8.0 pH Manufacturer's RangeName: Hydrion (O67) Urine & Saliva pH Paper 5.5-8.0 Warning that this item (Hydrion 067) is suitable for saliva and urine only (and does not work with every type of water) is hidden in the item description, not what is part of the product name. Although someone in the Q&A section claims that this item works for hydroponic solutions, they haven't reported accurate results for my 1100ppm tap water + Epsom salts + plant food mix. For me it is completely useless. If you want to test the pH of anything other than saliva or urine, consider purchasing a different item.
