Lamotte 3976A-H Dissolved Oxygen Test Kit Refill 25 Tests

Dissolved Oxygen Test Kit Refill

The Lamotte 3976A-H refill pack provides replacement reagents for dissolved oxygen analysis using a colorimetric test system. It is designed for technicians, educators and field operators who already own the compatible test kit and need to replenish consumable supplies for continued water-quality monitoring.

Capacity of 25 Tests per Pack

Each refill contains enough reagent for 25 individual determinations, giving a clear benchmark for planning routine sampling schedules. When the allocated tests are exhausted the kit cannot produce further results until another refill is obtained, so users tracking long-term studies should maintain a reserve supply.

Colorimetric Method Constraints

The colorimetric approach relies on visual or photometric colour comparison, which means accuracy depends on consistent lighting, proper vial handling and the analyst’s ability to discern subtle shade differences. Interfering substances in complex water matrices can also affect the reading, so the method is best suited to applications where these variables can be controlled.
