- Full function self-test of: sensor, battery and circuit integrity; and audible/visual alarms
Supported Gases:
- H2S - hydrogen sulfide
- CO - carbon monoxide
- O2 - oxygen
- HCN - hydrogen cyanide
- Cl2 - chlorine
- ClO2 - chlorine dioxide
- SO2 - sulfur dioxide
- O3 - ozone
- PH3 - phosphine
- NH3 - ammonia
- NO2 - nitrogen dioxide
- LEL combustibles
- PID - photo ionization
Description
- GasAlertMicro5 PID portable gas detector allows simultaneous monitoring of up to five atmospheric hazards including volatile organic compounds (VOCs), combustible gas (% LEL), oxygen, and a wide selection of individual electrochemical toxic sensors.
- Compact, lightweight, and rugged, the GasAlertMicro5 PID activates audible, visual and vibrating alarms in the event of a low, high, TWA or STEL alarm condition. VOCs can 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 paint thinners, benzene, solvents, butadiene, toluene, hexane, as well as vapors associated with fuels such as diesel, heating oil, gasoline, kerosene, and jet fuel.
- The GasAlertMicro5 PID’s integrated photoionization detector (PID) enables sensitive broad spectrum monitoring of volatile organic contaminants. Highly configurable to suit a range of applications, GasAlertMicro5 PID comes as either a diffusion or pumped instrument; with either NiMH rechargeable hot-swappable battery pack or normal alkaline and has optional datalogging capabilities.
