Water or air, measure H2S where it matters – right at the source.
Meet the new GS1440 and GS1440EX hydrogen sulfide sensors from Hach. Whether in water or air, you will have the direct H2S measurement you need to optimize your H2S treatment process and proactively control H2S before it causes issues.
