The 3887 handheld particle counter is the perfect economical tool for spot checks in particle sensitive areas. It's pre-programmed with ISO standards to certify cleanroom operations. The instrument can also be used to check the effectiveness of filters (such as HEPA) or as an initial investigation tool for IAQ studies, including mold remediation.
