Updated 22 days ago · Based on the Amazon listing and published specifications, not hands-on testing.
A rugged clip-on hydrogen sulfide monitor with a loud triple alarm and an event log for safety records. Look elsewhere for carbon monoxide detection, since the sensor watches one gas only.

Overview
Electrochemical button sensors, built by MSA and sealed against leakage, do the sensing in this Altair personal monitor, which clips on and watches the air for hydrogen sulfide. One button runs it, and flashing LEDs, a horn and an internal vibrator fire together when gas passes its set points.
Workers in areas where hydrogen sulfide can build up get a monitor that is hard to miss when it alarms, because light, sound and vibration fire at once. Its operating life is rated in years of service or a set budget of alarm time, so frequent alarms shorten it.
Who it's for
Field crews and site safety staff who must log exposure alarms get a wearable unit with downloadable event history. Homeowners shopping for carbon monoxide protection should look elsewhere, since this sensor reads hydrogen sulfide only.
Pros and cons
- Triple alarm: light, sound and vibration
- Rubberized housing resists dust and water
- Logs recent alarm and test events
- Infrared port for PC data download
- Detects hydrogen sulfide only, not carbon monoxide
- Service life capped by sensor rating
- Data download needs MSA adapter and software
- Dimensions not listed
Performance notes
Detection rests on an electrochemical cell that reacts to hydrogen sulfide, so readings depend on the sensor staying within its rated temperature and humidity band. Alarm reach comes from three channels at once, which matters in loud spaces where a horn alone gets missed. Long alarm periods draw down the rated operating budget faster than quiet days do.

Frequently asked questions
How big is the MSA Altair single-gas detector?
The listing does not give dimensions. It describes a clip-on personal monitor in a rubberized housing, so plan on wearing it on clothing rather than mounting it.
Does the MSA Altair 10092521 detect carbon monoxide?
No. Although it is listed with carbon monoxide detectors, it is a hydrogen sulfide monitor with an electrochemical sensor for that one gas.
How do I get alarm records off the MSA Altair?
It stores the last 25 alarm and test events and transmits them through its built-in IR port to a PC with the MSA infrared adapter and MSA Five Star Link version 4.3 software. Transmission time is a maximum of 60 seconds.
How is the MSA Altair operated?
It uses one-button operation, per the listing.
