The Honeywell Analytics IQ-XWY-B-NA IQ Force 4-gas detector is a handheld, four-gas detector that uses an electrochemical cell sensor to monitor ambient H₂S and carbon monoxide (CO) levels, a galvanic oxygen sensor to measure oxygen (O₂) levels, and a catalytic bead sensor to monitor ambient combustible gases continuously. It has audio, visual, and vibration alarms, which alert simultaneously when gases reach any of four preset levels. The detector has an alphanumeric LCD screen that shows real-time concentrations of the four monitored gases, the alarm type, the calibration requirements, and the battery life remaining. The LCD also displays a constant flashing heartbeat icon to indicate normal functioning. The detector is operated and adjusted with a single push button. It is used to indicate potentially harmful levels of gases naturally occurring in the environment; in a variety of occupational settings such as petroleum refineries, tanneries, sewage treatment facilities, and paper mills; and in other personal safety, educational, and ambient monitoring applications.

This detector is set to alert to when gas levels reach any of four limits: a warning level, indicating moderate danger; a danger level, indicating significant danger; a short-term exposure limit (STEL), the maximum gas concentration to which workers can be exposed continuously for a short period of time without serious risk; and a time-weighted average (TWA) limit, the maximum average exposure that personnel can experience over an eight-hour work shift without serious risk. Alarm levels are user-adjustable. The 95 dB audible alarm sounds at different tones to indicate the alarm type, and the flashing LED alarm and built-in vibration alarm help alert the user to potentially dangerous levels of gases in high-noise conditions. The detector logs and retains data of the 200 most recent gas exposure events, which it can transmit via an infrared USB adapter to a personal computer (both sold separately).

This product is powered by a rechargeable lithium ion battery that provides up to 22 hours of operational life per charge, and recharges in 8 hours. To ensure performance, the detector tests its sensor integrity, circuitry, and audible and visual alarms upon activation. It tests its battery upon activation and continuously during operation. This detector has a concussion-resistant case to help protect it against damage. It is water resistant, and is compatible with the Honeywell Analytics manual sample-draw kit and motorized sample-draw pump (both sold separately). It has a European Conformity (CE) and ATEX certification safety of electric and electronic equipment, and it is classified by Underwriters Laboratory (UL) to U.S. and Canadian standards as an Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I and II, Division I, Group A, B, C , D, and F. It has an ingress protection (IP) rating of 66/67.

A gas detector is a safety device that detects and monitors various toxic, combustible, and flammable gasses in an area, and which can also register a decrease in ambient oxygen. Gas detectors can be portable or stationary, and are typically classified by their detection methods, which include catalytic, electro-chemical, point infrared, open-path infrared, semiconductor, thermal path conductor, and paper tape detection. Gas detectors are first calibrated to known gasses that serve as a reference points. Their sensors can then be used to measure ambient gas concentrations in comparison to the calibration gasses. When gas concentrations exceed a pre-set limit, an alarm or signal is triggered, alerting the user to potential danger. Pre-set limits often include a low-alarm level, indicating a gas concentration that poses a moderate danger; a high-alarm level, indicating a gas concentration that poses a large danger; a short-term exposure limit (STEL), the maximum gas concentration to which workers can be exposed continuously for a short period of time without serious risk of harm, and time-weighted average (TWA) limit, the maximum average exposure personnel can experience over the course of an eight-hour work shift without serious risk of harm. Most gas detectors also feature LCD screens that provide a variety of information including gasses detected and their concentrations, pre-set exposure limits, and battery level.

Gas detectors have a variety of industrial and governmental applications, such as in fire and rescue, mining, construction, petroleum refineries, tanneries, sewage treatment facilities, and paper mills. Portable gas detectors are typically used to monitor the air around personnel, are worn on clothing or on belts or harnesses, and are powered with rechargeable or disposable batteries. They generally require periodic calibration, testing, and battery recharging or replacement, although some fixed-life detectors are designed to perform for a number of years without calibration or battery replacement before being discarded. Stationary gas detectors are typically powered electrically and mounted near the process area of a plant or control room. They also require periodic service, testing, and calibration.
