The Mettler Toledo InTap4000e/InTap4004e Portable Dissolved Oxygen Measuring Systems support portable dissolved oxygen measurement for beverage and process environments where at-line or spot-check oxygen readings are needed.
These systems are designed for use where operators need to verify dissolved oxygen values away from a fixed measuring point while maintaining practical access to measurement data.
The InTap4000e/InTap4004e family is suited for breweries, mineral water production, and related beverage applications where dissolved oxygen measurement can support routine quality checks and production monitoring.

The portable format provides flexibility for checking multiple locations without relying solely on permanently installed instrumentation.
