Product - COD Sampling

Sigma Sampling  

Water quality data relies on sample integrity. Even the most exacting laboratory analysis lacks compensation for improper sample collection, or physical and chemical alteration of a sample due to inappropriate transport and storage.

Correct sampling procedures deliver accurate lab results, a critical component when determining whether you have violated a permit or not. When your results and reputation depend on your sample, depend on Hach brand Sigma Samplers.
