Water

Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces.

We are proud to introduce our new digital pH meter, DPH-2. Like all ATAGO products, the DPH-2 is extremely easy to use. It has a compact, portable design and is water resistant ( IP67 ), so it can be cleaned under running water and submersed into water without any negative effects. It has an Automatic Temperature Compensation mechanism that function from 0 to 50°C. With these features, the DPH-2 is perfect for many different applications including food and beverage production control, brewing and fermentation, soil and hydroponics, cutting oils, alkali washing liquids, and other soluble solutions. Great Features at Great Price. *Calibrate at 3 points (4.0, 7.0 and 10.0).
