Model 546 pH/ORP Sensor
Brand: Barben AnalyticalThe versatile Model 546 is suitable for in-line sample stream applications using the 3/4" NPT process connection.
A similar 3/4" NPT connection on the rear of the sensor is used to mount the sensor in submersible and high pressure hot tap installations.
With tip lengths from 0.5 to 5.0" the 546 sensor can fit through extended pipe nipples and flanges to reach into the process and provide optimum pH/ORP measurement.
Features- Patented design increases sensor life, accuracy and reliability
- High resistance to poison- Reduced calibration offset error
- Large surface area reference junction eliminates plugging issues
- Eliminates error due to fluctuating pressure
- No exotic gel or polymer electrolyte which may be incompatible with the process
