Ideal for testing pH balance of drinking water, pool, aquarium, RO system, spa or hydroponics. - QUALITY AND STABILITY: Atlas Scientific’s pH test solution Standardized against NIST-certified references, each batch is manufactured under strict conditions to ensure quality and stability and is checked to verify calibration. Accurate to ±0.02 pH at 25°C. - PH INDICATOR KIT: pH is actually a measurement of the activity of hydrogen ions in the sample. pH is a numeric scale used to specify the acidity or basicity of an aqueous solution. The pH value of a neutral solution is 7.0. Solutions with a pH value below 7.0 are considered acidic and solutions with pH value above 7.0 are basic (alkaline). This pH calibration test solution is perfect calibrating pH. - FIRST AID MEASURES: Each of our pH 7.0 solutions are nontoxic in low quantities. Clean with soap and water if exposed to skin. Avoid ingestion and contact with eyes, In case of accident by inhalation remove casualty to fresh air and keep at rest. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. After contact with skin, wash immediately with plenty of water. - SET INCLUDES: pH 7.0 Calibration Solution, 4oz bottle (250 ml) - 2 year shelf life at room temperature. Keep container tightly closed in a cool, well-ventilated place. ## Images ![Calibration Solution pH 7.0 - pH Indicator & pH Test Equipment For Hydroponics, Food Processing, Aquariums, Pools, Water - Perfect For Precise pH Meter Calibration Use With pH Probe - 4oz Bottle - Image 1](https://m.media-amazon.com/images/I/61T3AaB19jL.jpg) ![Calibration Solution pH 7.0 - pH Indicator & pH Test Equipment For Hydroponics, Food Processing, Aquariums, Pools, Water - Perfect For Precise pH Meter Calibration Use With pH Probe - 4oz Bottle - Image 2](https://m.media-amazon.com/images/I/61jA-E8LprL.jpg) ![Calibration Solution pH 7.0 - pH Indicator & pH Test Equipment For Hydroponics, Food Processing, Aquariums, Pools, Water - Perfect For Precise pH Meter Calibration Use With pH Probe - 4oz Bottle - Image 3](https://m.media-amazon.com/images/I/61Rux2RsSqL.jpg) ![Calibration Solution pH 7.0 - pH Indicator & pH Test Equipment For Hydroponics, Food Processing, Aquariums, Pools, Water - Perfect For Precise pH Meter Calibration Use With pH Probe - 4oz Bottle - Image 4](https://m.media-amazon.com/images/I/71SyfFyqv6L.jpg) ![Calibration Solution pH 7.0 - pH Indicator & pH Test Equipment For Hydroponics, Food Processing, Aquariums, Pools, Water - Perfect For Precise pH Meter Calibration Use With pH Probe - 4oz Bottle - Image 5](https://m.media-amazon.com/images/I/61Vnkl0CDuL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Easy to use *by J***L on Reviewed in the United States 🇺🇸 on March 29, 2023* The item was grand and excellent!
