The Honeywell Analytics 54-45-90VD ToxiPro polycarbonate oxygen (O₂) single-gas detector is a handheld, single-gas detector that uses a galvanic oxygen sensor to measure oxygen continuously, and that has audio and visual alarms, which alert simultaneously when oxygen reaches either of two preset levels. The detector has a backlit, alphanumeric LCD screen that can be adjusted by the user to show the current gas level, the maximum and minimum gas level recorded during the current operating session, the battery level, and the time. The LCD display also features a blinking heartbeat icon to indicate normal functioning. It is operated and adjusted with a single push button. This detector is used to indicate potentially harmful levels of oxygen gas 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 factory-set to alert a low-alarm condition when the level of oxygen reaches 19.5% and a high-alarm condition when oxygen reaches 23.5%. The three bright, LED alarm bars flash yellow in low-alarm conditions and red in high-alarm conditions to help alert the user to potentially dangerous levels of oxygen in high-noise environments. Once the gas exposure alarm initiates, the detector records the maximum and minimum gas exposure reached during its current operating session. The detector logs and retains data of the 100 most recent gas exposure events, which it can transmit via an infrared USB adapter to a personal computer (both sold separately).

This detector is powered by a replaceable lithium manganese dioxide battery for up to one year or 9,000 hours of operating life. 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 comes with a built-in top ring to allow the unit to be clipped to a belt, waistband, or lapel. It has a clear polycarbonate body with a thermoplastic elastomer (TPE) overmold to help protect it against damage. It is water resistant, and is compatible with the Honeywell Analytics manual sample draw kit and vibrating alarm attachment (both sold separately). It has a European Conformity (CE) and ATEX certification for safety of electrical and electronic devices, 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, E, 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.
