Product Specification

ENV-40-pH pH Probe Operating principle
A pH (potential of Hydrogen) probe measures the hydrogen ion activity in a liquid. At the tip of a pH probe is a glass membrane. This glass membrane permits hydrogen ions from the liquid being measured to defuse into the outer layer of the glass, while larger ions remain in the solution. The difference in the concentration of hydrogen ions (outside the probe vs. inside the probe) creates a VERY small current. This current is proportional to the concentration of hydrogen ions in the liquid being measured.

This pH Probe can be fully submerged in fresh water or salt water, up to the BNC connector indefinitely.

ENV-40-pH pH Probe Typical Applications
• Standard lab use
• Field use
• Soil
• Low ionic and ultra-pure water
• High pH solutions (up to 14 pH)
• Samples containing heavy metals
• Hydroponics / aquaponics
• Beer, wine and other liquor
• Food safe
