pH Meter Pen Description

From measuring the safety of industrial chemicals to finding the optimum water balance for a home aquarium, measuring the pH levels of water is a useful ability to have. Ultra-portable and slim enough to fit into any pocket, the pH Meter Pen is the perfect device for determining the acidity or alkalinity of liquids. 

It's incredibly easy to use. Just immerse the electrode in the water and the reading will be displayed automatically after a short while. With an incredibly low 0.01pH error range, you may get higher accuracy than other pH meters. 

You won’t need to manually adjust the pH Meter Pen, just press the auto calibration button and it will be ready to use. This pH Meter features an automatic temperature compensation feature that accounts for any changes in temperature and adjusts the measurement accordingly.
