Msa 10116928 Multi-gas Detector Co H2S O2 Lcd

Product Description

The MSA 10116928 is a portable multi-gas detector designed to simultaneously monitor four atmospheric hazards: carbon monoxide (CO), combustible gases, hydrogen sulfide (H2S), and oxygen (O2). The unit features an LCD display for real-time readout of gas concentrations and is built for use in demanding field conditions, with an operating temperature range of -40 to 50 degrees C. An integral pump draws air samples to the sensor array, making it suitable for confined space entry and other scenarios where passive diffusion sampling is not adequate. Licensed industrial hygienists, safety professionals, and trade workers in HVAC, utilities, and petrochemical environments are the primary users.

This detector is used in confined space entry operations, industrial facility monitoring, utility work, and any environment where simultaneous detection of toxic and combustible gases is required by OSHA or site safety protocols. The wide operating temperature range makes it viable for both cold-weather outdoor jobs and high-heat industrial interiors. The rechargeable battery pack paired with AA backup capability supports extended shift use without interruption.

Key Features

• Monitors four gases simultaneously: CO (0-999 ppm), combustible gases (0-100% LEL), H2S (0-200 ppm), and O2 (0-25% Vol.)
• Alarm thresholds configurable for each channel: CO at 25-100 ppm, combustible at 10-20% LEL, H2S at 10-15 ppm, O2 at 19.5-23%
• Integral pump for active air sampling in confined spaces and remote locations
• LCD display provides clear, real-time concentration readout for all four gas channels
• Rechargeable lithium-ion battery pack included; also accepts AA batteries for field backup
• Kit includes calibration cap, charger, tubing, rechargeable battery pack, and CD manual for complete out-of-box readiness

Compatibility

Designed for use as a portable multi-gas detection instrument in industrial, utility, and confined space entry applications where simultaneous CO, combustible gas, H2S, and O2 monitoring is required.

Installation Notes

This instrument is deployed and operated by qualified safety personnel or trained trade workers following applicable OSHA confined space entry regulations and site-specific gas monitoring procedures. Before each use, perform a bump test and zero calibration using the included calibration cap and appropriate calibration gas per the manufacturer procedures in the CD manual. Keep the integral pump inlet clear of debris and inspect tubing for cracks or blockages that could compromise sample integrity. Do not expose the sensor array to high concentrations of silicone vapors or other known sensor poisons, as this can degrade sensor accuracy over time.
