Maintains Accuracy with Reactive Gas Sensors
Sulfur dioxide is a reactive compound that can interact with wetted surfaces inside regulators and tubing.
Using a stable calibration reference concentration helps maintain reliable electrochemical sensor response during verification procedures.
Custom Mixture Options
Made-to-order calibration standard.
Alternate concentrations and multi-component mixtures available for application-specific monitoring and cross-interference testing.
