Dissolved oxygen sampler

TL;DR: In this article, the authors proposed a dissolved oxygen sampler based on the utility model, which is applied to sampling for the analysis of the dissolved oxygen in water samples of at certain depth underwater in environment monitoring.

Abstract: The utility model provides a dissolved oxygen sampler. The sampler comprises a base, a bracket, a hoisting ring, iron sheet frames, a left culture flask, a right culture flask, rubber plugs, a thermometer, a floating ball, a silicone tube and a long silicone tube. The sampler disclosed by the utility model is applied to sampling for the analysis of the dissolved oxygen in water samples of at certain depth underwater in environment monitoring, and is also applicable to sampling of water samples under a bridge on a bridge floor at certain height. Through the adoption of the sampler disclosed by the utility model, the situation that air is not dissolved in the water samples in the collecting process can be ensured, the collected water samples are not in contact with air, and at the same time, the temperature of the water samples can be accurately measured.
