About This

  • Ensures accurate readings - Our pH calibration solution helps maintain the accuracy and reliability of a pH pen, probe, or tester. Calibration ensures accurate readings. This helps keep the pH level in check for the health of plants, swimmers, or aquatic life.
  • NIST Traceable - Our pH calibration solutions are NIST traceable and meet the highest quality standards. This set includes two crucial pH levels, pH 4 and pH 7, allowing you to calibrate a wide range of pH instruments.
  • Improves the longevity of the pH pen or tester - Regular calibration helps extend the life of your pH meters by maintaining their performance. Useful for providing accurate pH in hydroponics, aquariums, swimming pools, or gardens.
  • Easy-to-use and long shelf life - Our electrolyte solutions are ready-to-use right out of the bottle, saving you time and effort. Our pH calibration solutions don't need frequent replacements as they have a long shelf life.
  • How to calibrate - Make sure your pH pen or probe is clean and hydrated. Turn it on. Place the probe tip in a fresh pH 7.0 calibration solution. Rinse the pen or probe tip in clean tap water and shake off the excess. Calibrate to pH 4. A calibration confirmation will appear to show a successful calibration. Recalibrate if the symbol disappears.

Frequently Asked Questions

Everything you need to know about growing a beautiful garden

The best time to plant vegetables depends on your climate zone. Generally, cool-season crops like lettuce and peas thrive in early spring, while warm-season crops like tomatoes and peppers should be planted after the last frost date.
Most gardens need about 1 inch of water per week, either from rainfall or irrigation. Water deeply but less frequently to encourage strong root growth. Early morning is the best time to water to minimize evaporation and disease.
Loamy soil with good drainage is ideal for most plants. It should be rich in organic matter, have a pH between 6.0-7.0, and retain moisture while allowing excess water to drain. Adding compost annually improves soil structure and fertility.
Companion planting, crop rotation, and encouraging beneficial insects are effective natural pest control methods. Marigolds deter many pests, while ladybugs and lacewings eat aphids. Regular inspection and hand-picking larger pests also helps.
