Fast-response pH Sensor, 6589

Simple, accurate pH measurement in sensors designed for minimal maintenance in sampling, profiling, and long-term monitoring applications.

• Faster response time in sampling and profiling applications
• Maintains fast response time in Low Ionic Strength (LIS) and cold waters
• Maintains fast response time throughout life of sensor
• Stable readings and like-new performance in instruments with aging or contaminated connectors

YSI pH and pH/ORP sensors have been carefully designed to perform under all ionic strength conditions, from seawater with a conductivity of 53000 μS/cm, to 'average' freshwater lakes and rivers with conductivities of 200 to 1500 μS/cm, to pure mountain streams with conductivities as low as 15 μS/cm, which has historically been the most difficult medium with respect to accuracy, quick response to pH changes, and minimal flow dependence.

Use with: All 6-Series sondes with a user-replaceable pH port. Strengths: Provides rugged general monitoring flexibility. Produces  fast, stable readings in LIS Water and other difficult pH measuring environments. New design restores old instrument’s pH response time to like new.

Amplified sensor provides fast response and increased stability over standard pH sensors, despite the wear and tear of your instrument.
