WSPH4001 Pure Water pH Sensor

The WSPH4001 pure water pH sensor is designed for continuous pH measurement in all kinds of pure and high-purity water. The sensor detects the concentration of H+ ions in the water and converts the electrochemical signal into a voltage, which a pH meter converts into a pH reading. A solid dielectric with a large-area PTFE liquid junction resists blocking and is easy to maintain, while a long reference diffusion channel extends electrode life. Because the electrolyte never needs refilling, maintenance is low. With a flow cell it is used in thermal power plant water circuits.

Features

• Solid dielectric and large-area PTFE liquid junction, difficult to block and easy to maintain
• Long-distance reference diffusion channel extends electrode service life
• No electrolyte refilling, so maintenance is low
• Full 0 … 14 pH range with accuracy ≤ 0.02 pH
• Fast response (≤ 10 s), slope ≥ 96% and good repeatability
• Low drift: ≤ 0.03 pH per 24 h, non-accumulating
• Rotary locking installation: a quarter turn inserts or removes the electrode; upper ¾ NPT thread
• 5 m cable as standard, length can be modified

Applications

• Pure water
• High-purity water
• Thermal power plants (with flow cell)
