The Benefits of Bypass Sensor Holders:
 
In high-demand water treatment and industrial processing, accuracy isn't just a goal—it’s a requirement. Standard "in-line holder" installations often expose sensitive electrodes and sensors to turbulent flows and harsh conditions that can lead to premature failure or skewed measurements, using a Bypass Probe Holder (referred to "off-line" or "sample line" housings) provides a controlled environment for the continuous monitoring of pH, Redox and chlorine levels without exposing the delicate sensors to high pressure, turbulence, or abrasive flow of the main process stream ensuring they perform at their absolute peak an essential component in industrial water treatment applications where sensor longevity & ease of maintenance are priorities.
 

Stable Measurement Environment:
 
Whether your managing a small municipal pool or an industrial complex water treatment system incorporating by diverting a small side-stream of process water you eliminate the fluctuations normally found in the main flow stream creating a consistent stable measurement environment & significantly reducing sensor degradation.
 
Integrated Flow Control:
 
Our range of pH, redox (orp) and chlorine bypass holders provide real-time safety through an integrated flow switch that acts as a failsafe in the event the water flow drops below a critical level the switch can trigger an alarm or automatically disabled the dosing pumps preventing chemical overdosing or sensor dry-out.
 
Simplified Maintenance:
 
Perform simple tasks such as electrode calibrations and sensor replacements without shutting down your entire main process line for routine maintenance by closing the bypass isolation valves you can remove the sensor for cleaning and calibration or replace it all within minutes with minimal impact to the working environment.
 

Flow-Through pH and Redox Electrode Holder
 
Designed for precise and continuous monitoring in industrial water treatment medium pressure applications installed direct into the main flow stream or through a bypass sample line loop with the internal chamber designed to minimise turbulence & air entrapment around the sensing tip for optimal stable readings, characterised with good transparency and excellent resistance to chemical agents this holder is the ideal interface for integrating standard 12mm diameter pH, Redox and conductivity electrodes into your piping system.
