SE101 pH Sensor

Robust Noryl-body laboratory pH sensor with analog connection for mobile and field measurements across the full pH range.

The SE101 is a durable laboratory pH sensor built with a Noryl plastic body to withstand demanding laboratory and field conditions. Its polyester fiber wick junction resists contamination and delivers stable, reliable readings over time, while the polymer electrolyte design eliminates the need for refilling. Paired with the Portavo portable meter, it enables convenient calibration and measurement anywhere, making it ideal for environmental analysis and water management tasks.
