This industrial PTFE pH sensor measures pH and temperature in corrosive process liquids and industrial water systems.

The 870002-PHF combines a glass sensing element with a corrosion-resistant PTFE housing for online monitoring in chemical processing, wastewater treatment and other industrial applications. Its 0–14 pH range and 0–60 °C operating range cover a variety of water treatment conditions.

A large-area reference junction and extended reference diffusion path help support stable measurements while reducing susceptibility to clogging. Upper and lower 3/4 in. NPT threads allow installation in a tank or pipeline, while a direct low-noise cable connects the electrode to a compatible pH analyzer.
