PHS-1701 portable pH meter is a digital display PH meter, with LCD digital display, which can display PH and temperature values simultaneously. The instrument applies to the labs in junior college institutions, research institutes, environmental monitoring, industrial and mining enterprises, and other departments or field sampling to determine the aqueous solutions' PH values and potential (mV) values. Equipped with an ORP electrode, it can measure the solution's ORP (oxidation-reduction potential) value; equipped with the ion-specific electrode, it can measure the electrode potential value of the electrode.
What‘s pH?
PH is a measure of the hydrogen ion activity in a solution. Pure water that contains an equal balance of positive hydrogen ions (H +) and negative hydroxide ions (OH -) has a neutral pH.
● Solutions with a higher concentration of hydrogen ions (H +) than pure water are acidic and have a pH of less than 7.
● Solutions with a higher concentration of hydroxide ions (OH -) than water is basic (alkaline) and have a pH greater than 7.
Why monitor the pH of water?
PH measurement is a key step in many water testing and purification processes:
● A change in the pH level of water can alter the behavior of chemicals in the water.
● PH affects product quality and consumer safety. Changes in pH can alter the flavor, color, shelf-life, product stability, and acidity.
● Inadequate pH of tap water can cause corrosion in the distribution system and can allow harmful heavy metals to leach out.
● Managing industrial water pH environments helps prevent corrosion and damage to equipment.
● In natural environments, pH can affect plants and animals.
