Five-Gas Detector

GasAlertMicro 5 PID portable gas detector simultaneously monitors up to five atmospheric hazards including volatile organic compounds (VOCs), oxygen, combustible gas (% LEL) and a wide selection of toxic gases. Compact and lightweight, GasAlertMicro 5 PID activates audible, visual and vibrating alarms in the event of a low, high, TWA or STEL alarm condition.

Smaller and over 50% lighter than competitive instruments Water-resistant design with integral concussionproof enclosure Continuous LCD shows simultaneous gas concentrations for five gases 0 - 1000 ppm measurement of VOCs (Volatile Organic Compounds) Integral motorized pump option for remote sampling Two power options: AA alkaline or rechargeable hot-swappable battery packs Provides 95 dB alarm tone and two bright wideangled alarm bars Equipped with internal vibrating alarm for high noise areas Multi-language support in English, French, German, Spanish and Portuguese LCD backlight automatically activates on alarm, on demand and in low light conditions Four alarm levels: instantaneous Low and High Alarm for all gases; TWA (time-weighted average) and STEL (short-term exposure limit) for VOCs and toxic gases Simple automatic calibration procedure; compatible with BW MicroDock II automatic test and calibration station Records TWA, STEL and maximum exposures to gas and displays readings on command Complete range of user selectable options Full function self-test of: sensor, battery and circuit integrity; and audible/visual alarms

VOCs present multiple potential threats in the workplace environment. VOCs are characterized by their tendency to evaporate easily at room temperature and include substances such as solvents, paint thinners, benzene, butadiene, hexane, toluene, as well as vapors associated with fuels such as gasoline, diesel, heating oil, kerosene and jet fuel. The GasAlertMicro 5 PID抯 integrated photoionization detector (PID) enables sensitive broad spectrum monitoring of volatile organic contaminants.

Highly configurable to suit a range of applications, GasAlertMicro 5 PID comes as a diffusion or pumped instrument; with either alkaline or NiMH rechargeable hot-swappable battery pack and has optional datalogging capabilities. Standard features include confidence beep, automatic calibration, full function self-test and an extended selection of user-settable field options.
