Description

CID1 ALTAIR® 4XR Multigas Monitor

The CID1 ALTAIR® 4XR Multigas Monitor is a rugged, fast-responding 4-gas detection device engineered for demanding hazardous environments, including chemical processing, oil & gas facilities, and manufacturing plants. Designed to monitor combustible gases (LEL), oxygen deficiency/enrichment (O₂), and toxic gases such as CO, H₂S, SO₂, and NO₂, this monitor ensures worker safety in critical applications. With global intrinsic safety ratings (Class I, Div 1, ATEX, IECEx) and integrated safety features like MotionAlert™ and InstantAlert™, it provides continuous protection across harsh industrial sites.

Powered by patented MSA XCell® ASIC-driven sensors, the ALTAIR 4XR achieves response times under 15 seconds—up to twice as fast as the industry average—while using 50% less test gas during calibration. Built for extreme field operations, it features a glove-friendly single-button interface, an ultra-rugged rubber-armored housing, and 24-hour continuous battery runtime to support long multi-shift duties. The unit withstands 25 drops from 4 feet, resists 25-foot concrete falls, and is submersible under its IP68 rating, making it an essential tool for plant turnarounds and confined space entry.

Key Features:

✅ Class I, Div 1 (Groups A, B, C, D) & ATEX/IECEx Ex ia da IIC T4 Ga hazardous area certifications
✅ Patented MSA XCell® ASIC sensors with 4+ year expected life and predictive end-of-life warnings
✅ IP68 dust/water ingress rating (submersible up to 2m for 1 hour) & MIL-STD-810G drop tested
✅ Optional phosphorescent glow-in-the-dark housing for low-light visibility
✅ Real-time detection for LEL, O₂, CO, H₂S, H₂S-LC, SO₂, and NO₂
✅ MotionAlert™ (man-down alarm) and InstantAlert™ (manual emergency callout) safety systems
✅ Long-life rechargeable Li-polymer battery with 24-hour continuous operating runtime
✅ 95 dB audible horn, ultra-bright top/bottom LEDs, and strong vibrating alarm
✅ Glove-friendly 3-button physical interface with large visual bump test compliance checkmark
