| Category |  | Disposable Single Gas Detectors Altair Single-Gas Detectors offer cost-effective monitoring for CO, H2S or O2 providing over two years of maintenance-free performance. One button operation with no sensor or battery changes necessary. |  | Rechargeable Single Gas Detectors Altair Pro Single-Gas Detector versions available for CO, H2S, O2, NH3, Cl2, ClO2, NO2, SO2, HCN, and PH3. Sensors and battery are easily replaced to keep the unit performing for years. |  | MSA Altair 4X Multigas Detectors Altair 4X Multigas Detector for LEL, CO, H2S and O2. Features include; expanded 24 hour run-time, extended-life XCell sensors with typical life greater than 4 years, exclusive end-of- sensor- life warning and 3-year warranty. | 
| MSA Altair 4X Multigas Detector Kits Kits include Altair 4X gas detector, calibration gas, regulator and case. Everything you need to keep your gas detector calibrated, tested and ready to go 24/7 |  | MSA Altair 5 Multigas Detectors- *Updated* Altair 5 Multigas Detector provides up to 6-gas capability and now features sensors for the following gases: chlorine, nitrogen dioxide, ammonia, phosphine, hydrogen cyanide and chlorine dioxide. With integrated pump samples can be drawn from 50 feet away within nine seconds, or from 80 feet away within 15 seconds. Color or monochrome display option and 2-year warranty. |  | MSA Altair 5X Multigas Detectors - * New* Four-year sensor life on LEL, O2, CO, H2S, SO2, and IR sensors –60% longer than industry average. Monitors up to six gases simultaneously. Full three-year warranty. The ALTAIR 5X Detector allows for an industry-first LEL,O2, CO, H2S, and SO2 60-second span calibration and 10-second bump test time. |  | MSA Sirius Multigas Detectors Sirius Multigas Detector-combines high-performance PID (photoionization detection) and four-gas capability within one instrument allowing for detection of hundreds of chemicals. Readings for combustible gas, CO, H2S, O2 and volatile organic compounds (VOCs) with their character names are clearly and simultaneously exhibited on the display. The Sirius Multigas Detector can be used with or without the PID mode; when only a four gas detector is needed users can turn off VOC readings. | 
| Galaxy Test Systems Calibrate and bump test MSA multigas detectors quickly and easily. Options include cylinder holder, recharging, and smart system with memory card for easy data record storage. Up to 10 systems can be linked for maintaining larger fleets of gas detectors. Use this system with Altair 4 /4X, Altair 5 / 5X, and Sirius multigas detectors. |  | Biosystems Gas Detectors Biosystems ToxiLtd is a 2-year disposable gas detector providing a cost effective solution for gas monitoring. Biosystems ToxiPro is a fully serviceable, reusable single-sensor gas detector with replaceable battery and sensor. Sensor option include: Oxygen(O2), Carbon Monoxide(CO2), Hydrogen Sulfide(SO2), Nitrogen Dioxide(NO2), Phospine(PH3), Chlorine(CI2), and Ammonia(NH3). |  | Calibration Gas Cylinders Single gas and multigas cylinders for calibrating MSA gas detectors. Altair 4X Accessories Replacement sensors, battery packs, chargers, sampling lines, pump probes and more. Altair 5 & 5X Accessories Replacement sensors, battery packs, chargers, sampling lines, pump probes and more. |  | Air Quality Meters & Gas Leak Detectors Monitor indoor air quality for Carbon Dioxide (CO2), humidity and temperature.
