The MACURCO 37-0081-4134-2 is a carbon monoxide calibration gas cylinder containing a 200 PPM CO concentration in a 17-liter cylinder. It is used to calibrate and verify the accuracy of carbon monoxide detection equipment in residential, commercial, and industrial applications. Licensed HVAC technicians, safety professionals, and building maintenance personnel use this calibration gas as part of routine sensor verification and compliance testing. The 200 PPM concentration is a standard span-gas value for CO detector calibration, making this cylinder a practical consumable for field service and scheduled maintenance programs.
This calibration gas cylinder is suited for use with compatible fixed and portable CO detection systems that require periodic bump testing or full span calibration. It is commonly used in settings where CO detectors are installed for life-safety compliance, including commercial HVAC mechanical rooms, boiler rooms, parking structures, and residential service calls. Each cylinder contains a single unit of use, consistent with standard calibration procedures for gas detection equipment.
Designed for use with carbon monoxide detection instruments that accept standard calibration gas cylinders at a 200 PPM CO concentration. Verify regulator and inlet fitting compatibility with your specific detector or calibration equipment before use.
Calibration gas application should be performed by a qualified technician familiar with the detector manufacturer's calibration procedure. Store and transport the cylinder upright in a well-ventilated area away from heat sources, open flame, and direct sunlight. Follow all applicable OSHA and local safety codes governing the handling of compressed gas cylinders. Do not use the cylinder beyond its labeled expiration date, as CO concentration accuracy degrades over time.
