Yes. The MSA ALTAIR 5X (part 10165446) is a strong choice because it detects five gas types out of the box — combustible gas (LEL), oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S) and volatile organic compounds (VOCs) via its PID sensor — and ships as a complete pumped kit with a color display, internal pump, a 10-ft (3 m) sampling line and a 1-ft (305 mm) probe, so you can remotely draw and test the atmosphere inside a tank, vessel or manhole before anyone enters. It monitors up to 6 gases simultaneously with interchangeable XCell sensors, is intrinsically safe (UL 913 / CAN/CSA C22.2), survives a 10-ft (3 m) drop, carries a minimum IP65 rating, and adds MotionAlert (man-down) and InstantAlert (manual panic) alarms.

The MSA ALTAIR 5X 10165446 detects five gas types as standard — combustible gas (LEL), oxygen (O₂), carbon monoxide (CO), hydrogen sulfide (H₂S) and volatile organic compounds (VOCs) through its PID sensor — and can monitor up to 6 gases simultaneously using interchangeable XCell sensors. It is approved to UL 913 and CAN/CSA C22.2 for intrinsic safety in hazardous (classified) locations, and carries a minimum IP65 rating (third-party certified) for dust and water ingress.

A PID (photoionization detector) is a sensor option on the MSA ALTAIR 5X that detects volatile organic compounds (VOCs) — vapors that a standard LEL sensor may miss at low concentrations. On the 10165446, MSA's advanced PID combines with its XCell sensors on one instrument, making it a key tool for industrial hygiene, HazMat response, and LDAR (leak detection and repair), as well as everyday safety and industrial operations. PID data integrates into MSA's fleet-management infrastructure alongside the instrument's other gas readings.

The MSA ALTAIR 5X 10165446 uses MSA XCell sensors with these standard measuring ranges: combustible gas (LEL) 0–100% LEL (or 0–5% CH₄), oxygen (O₂) 0–30% by volume, carbon monoxide (CO) 0–1999 ppm, and hydrogen sulfide (H₂S) 0–200 ppm, plus a PID sensor for detecting volatile organic compounds (VOCs). Because the XCell slots are plug-and-play, the instrument can be reconfigured with other sensors (up to 6 gases) if your application changes.

XCell Sensor Technology is MSA's platform of interchangeable, plug-and-play sensors used in the ALTAIR 5X, each built with a proprietary embedded ASIC microchip that drives the sensor and outputs a digital signal. This design performs real-time environmental corrections and delivers an industry-first 60-second span calibration with sensor response and clear times under 15 seconds on LEL, O₂, CO and H₂S — about 50% faster than the industry average. XCell sensors are rated for up to 4 years of life on those gases, about 60% longer than the industry average, and include an MSA-exclusive end-of-sensor-life warning.

MotionAlert and InstantAlert are two MSA-exclusive safety alarms built into the ALTAIR 5X. MotionAlert is a man-down feature that triggers automatically when the detector senses no movement, signaling that the wearer may be immobile. InstantAlert is a manually activated panic alarm the user can trigger to warn others of a dangerous situation. Both are backed by visual, vibrating and audible alarms, making them ideal for confined-space work where there is no direct line of sight.

Yes. The MSA ALTAIR 5X 10165446 includes Bluetooth as a standard feature, and pairing it with the free MSA ALTAIR Connect app (available on Google Play for compatible Android devices) turns a phone into a safety and productivity tool. Through the app you can view live gas-detection readings and man-down alerts, configure instruments remotely, automate gas-detector records and events, and send gas alarms via text — driving greater productivity and supervisory awareness of worker safety.

The internal pump lets the ALTAIR 5X actively pull air samples through its 10-ft (3 m) sampling line and 1-ft (305 mm) probe, so you can remotely test the atmosphere deep inside a confined space before entering — something a diffusion (passive) detector cannot do, since diffusion units only read the air immediately around them. On the 10165446 the internal pump has a recessed inlet that minimizes snag hazards and break points, making it a pumped monitor purpose-built for pre-entry sampling.

The MSA ALTAIR 5X offers an industry-first 60-second span calibration and a 10-second bump test, with sensor response and clear times under 15 seconds on LEL, O₂, CO and H₂S — about 50% faster than the industry average — helping deliver typical cost savings of more than 50% on calibration gas, replacement sensors and maintenance. Calibration and bump testing can be automated with the MSA GALAXY GX2 Automated Test System, and fleets can be managed through MSA Grid software.

The MSA ALTAIR 5X 10165446 is built for demanding field use: it has a rugged polycarbonate housing that survives a 10-ft (3 m) drop test and carries a minimum IP65 rating (third-party certified) against dust and water ingress. It weighs about 0.66 lb (0.30 kg), has large buttons that can be operated with a gloved hand, and supports visual, vibrating and audible alarms plus data logging for a full record of exposures.

The MSA ALTAIR 5X 10165446 is a Deluxe kit that includes the ALTAIR 5X detector with a color display and internal pump, configured for LEL, O₂, CO, H₂S and PID, plus a 10-ft (3 m) sampling line (PN 10040665) and a 1-ft (305 mm) straight probe (PN 10042621). It is covered by a 3-year manufacturer instrument warranty, and MSA rates its XCell sensors for LEL, O₂, CO and H₂S at up to 4 years of expected life — about 60% longer than the industry average. It ships from Industrial Safety Products with free shipping (note: gas meters are not eligible for returns or exchanges).

Both are the same rugged, intrinsically safe (UL 913) ALTAIR 5X platform with XCell sensors, Bluetooth and GALAXY GX2 compatibility, but the 10165446 adds an advanced PID (photoionization) sensor. A standard 4-gas ALTAIR 5X detects LEL, O₂, CO and H₂S; the PID version also detects volatile organic compounds (VOCs), which is essential for industrial hygiene, HazMat and LDAR (leak detection and repair) work where low-level vapors must be found. Choose the PID model (10165446) if you need VOC detection on one instrument; a standard 4-gas unit is enough if your hazards are limited to combustible gas, oxygen, CO and H₂S. Both are available at Industrial Safety Products.
