Bluelab Soil pH Pen

by Bluelab

A handy solution made easy! The Bluelab Soil pH Pen provides a pH and temperature reading of soils and media, so you know that the right nutrients will be made available to your plants. In soils or growing media, pH strongly influences the availability of the microorganisms to plants in the soil. Now you can closely monitor and adjust the pH levels to optimize plant health and performance. It will also measure solutions too. Now, isn't that handy? Not suitable for measuring Distilled, RO (Reverse Osmosis) or De-ionized water as the ionic strength is too low for the meter to read pH.

- Direct measurement of pH and temperature from soils/media
- Measures pH and temperature of solutions
- Integrated storage cap and dibber
- Fully Waterproof
- Successful pH calibration indicator
