PORTACAL® Methyl Mercaptan (CH₃SH) Calibration Gas is designed for the calibration, bump testing, and verification of compatible methyl mercaptan gas detectors, CH₃SH sensors, and monitoring instruments.

Methyl mercaptan (CH₃SH), also known as methanethiol, is a colorless, flammable gas with a strong, distinctive odor. It may be encountered in petroleum refining, natural gas operations, chemical manufacturing, pulp and paper processing, wastewater treatment, and other industrial environments where accurate methyl mercaptan monitoring may be required.

PORTACAL® Methyl Mercaptan Calibration Gas provides a known concentration of methyl mercaptan to help verify that compatible CH₃SH sensors, portable gas detectors, fixed gas detection systems, and industrial gas monitoring instruments are functioning and responding properly.
