The BW Technologies QT-XWHM-R-Y-NA AlertQuattro 4- detector
with rechargeable battery is a handheld, four- detector that
uses an electro cell sensor to monitor ambient H2S,
oxygen (O2), and carbon monoxide (CO) levels and a catalytic bead
sensor to monitor ambient combustible es continuously, and
that has audio, visual, and vibration alarms, which alert
simultaneously when es reach any of four preset levels. The
detector has an alphanumeric LCD screen that shows real-time
concentration of four monitored es, the alarm type, the
calibration requirements, the self-test pass or fail, 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 es naturally occurring
in the environment; in a variety of occupational settings such as
petroleum refineries, tanneries, sewage facilities, and
paper mills; and in other personal safety, educational, and
ambient monitoring applications.
This detector is set to alert to when levels reach any of
four limits: a low-alarm level, indicating moderate danger; a
high-alarm level, indicating significant danger; a short-term
exposure limit (STEL), the maximum 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. The 95 dB audible
alarm sounds at different speeds to indicate the alarm type, and
the five bright, LED alarm bars and the built-in vibration alarm
help alert the user to potentially dangerous levels of es in
high-noise conditions. The detector logs and retains data of the
10 most recent exposure events, which it can transmit via an
infrared Datalink USB adapter to a personal computer (both sold
separately).
This product is powered by a rechargeable lithium polymer battery
that provides up to 13 hours of operational life per charge. 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. The detector also features an automatic shutdown mode
for additional safety, which activates when the detector fails
its self-test. This detector comes with a back-ed alligator
clip to allow the unit to be worn on a belt, waistband, or lapel,
and a concussion-resistant boot to help protect it against
damage. It is water resistant, and is compatible with the BW
Technologies MicroDock II automatic test system (sold
separately). It has a European Conformity (CE) and ATEX
certification in accordance with Directive 2004/108/EC for
electromagnetic compatibility 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, Division I, Group A,
B, C , and D. It has an ingress protection (IP) rating of 66/67.

A detector is a safety device that detects and monitors
various toxic, combustible, and flammable ses in an area, and
which can also register a decrease in ambient oxygen.
detectors can be portable or stationary, and are typically
classified by their detection methods, which include catalytic,
electro-, point infrared, open-path infrared,
semiconductor, thermal path conductor, and paper tape detection.
detectors are first calibrated to known ses that serve as
a reference points. Their sensors can then be used to measure
ambient concentrations in comparison to the calibration
ses. When 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
concentration that poses a moderate danger; a high-alarm level,
indicating a concentration that poses a large danger; a
short-term exposure limit (STEL), the maximum 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 detectors also feature LCD screens
that provide a variety of information including ses detected
and their concentrations, pre-set exposure limits, and battery
level.
detectors have a variety of industrial and governmental
applications, such as in fire and rescue, mining, construction,
petroleum refineries, tanneries, sewage facilities, and
paper mills. Portable 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 dided.
Stationary detectors are typically powered electrically and
ed near the process area of a or control room. They
also require periodic service, testing, and calibration.
BW Technologies by Honeywell manufactures and distributes
portable and fixed monitoring equipment for use in a wide
range of industries. The company, founded in 1987, is based in
Canada in Calgary, Alberta.
