PH Pens

Perfect for quick and easy pH
and temperature readings direct
from your solution.
The Bluelab® pH Pen is the preferred option for handheld pH meters. It provides a compact, quick and handy
way to manage the success of your crops and helps
ensure maximum uptake of nutrients.
A key parameter that affects nutrient uptake in plants
is whether your solution is acid or alkaline. We measure
this in pH.
Teamed with our Bluelab® Conductivity Pen you have a
robust, convenient and accurate measurement system.

• Backlit LCD display
• Double junction probe (not replaceable)
• Simple two-point calibration process with 30-day
calibration indicator
• Hold reading function
• Low battery indicator
• Auto-off function
