What Does H₂S-LC Mean?
The H₂S-LC designation refers to the detector's low-concentration hydrogen sulfide sensor. Compared with a standard H₂S configuration, this sensor is intended for more precise monitoring at relatively low concentrations.
For this model, the sensor provides:
Measurement from 0 to 100.0 ppm
0.1 ppm resolution
Factory low alarm at 5 ppm
Factory high alarm at 10 ppm
Typical response time of less than 15 seconds
The alarm settings should not be confused with the sensor's full measurement range. The detector can measure beyond the 5 and 10 ppm alarm thresholds, up to its documented 100.0 ppm range.
Alarm and Display System
The ALTAIR 2X is designed to give the wearer several warning signals when an alarm condition occurs:
Visual LED indication for quick recognition
Audible alarm for environments where the display may not be visible
Vibration alarm for tactile notification
Display readout for viewing the gas concentration and instrument status
Using multiple alarm methods helps make gas warnings easier to recognize during active field work.
Compact Design for Personal Monitoring
At approximately 110 g, the ALTAIR 2X H₂S-LC is designed to remain lightweight when worn or carried throughout a work shift. Its compact housing is suitable for workers who need dedicated H₂S monitoring without carrying a larger multi-gas detector.
The IP67 rating provides protection against dust and temporary water exposure under the applicable testing conditions.
Data and Maintenance
The ALTAIR 2X platform supports event and measurement data recording, which can help organizations maintain records of detector activity and alarm events. MSA also identifies compatibility with its gas-detection testing and management ecosystem.
For dependable operation, the detector should be inspected, functionally tested, calibrated, and maintained according to MSA's instructions and the requirements of the workplace safety program.
Typical Applications
The ALTAIR 2X H₂S-LC can be considered for applications where low-level hydrogen sulfide monitoring is required, including:
Industrial maintenance
Chemical and process industries
Oil and gas operations
Utilities
Plant maintenance and turnarounds
Confined-space operations
Construction
Mining
Emergency response
General industrial workplaces
The correct application depends on the site's hazard assessment, required exposure limits, detector approvals, and operating procedures.
Important Safety Information
This detector is a professional gas-monitoring instrument and should be operated according to the MSA instruction manual, applicable approvals, and workplace safety procedures.
The 5 ppm and 10 ppm values are the factory-set low and high alarm thresholds, not the maximum detection capability of the sensor. The documented H₂S-LC measurement range is 0–100.0 ppm.
Regular inspection, bump testing, calibration, and maintenance should be performed as required. Always verify the approval markings and operating limitations of the actual instrument before use in hazardous locations.
Summary
The MSA Safety Works ALTAIR 2X H₂S-LC Gas Detector is a compact personal monitor designed for low-concentration hydrogen sulfide detection. With a 0–100.0 ppm range, 0.1 ppm resolution, 5/10 ppm factory alarm settings, and multiple alarm indicators, it provides a practical solution for personal H₂S monitoring in professional environments.
