YSI pH and pH/ORP sensors have been carefully designed to perform under all ionic strength conditions, from seawater with a conductivity of 53,000 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.
6589FR Fast Response pH Sensor:
Amplified sensor provides fast response and increased stability over standard pH sensors, despite the wear and tear of your instrument.
- 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
Sensor is available for use on the following sondes:
- 600XL & 600XLM
- 600DW & 6920DW
- 6820 V2 & 6920 V2
- 6600 V2 & 6600EDS V2
