Multi-Gas Detector for for H2S, CO, O2, Combustibles

The compact and versatile GasAlertMicroClip simultaneously monitors up to four gases, including hydrogen sulfide, carbon monoxide, oxygen and combustibles (LEL) and displays gas concentrations on a large LCD readout screen. Compact and versatile, the GasAlertMicroClip is the ideal multi-gas monitoring answer to confined space entry.

The GasAlertMicroClip is based on the revolutionary MicroCel family of miniaturized gas sensors from City Technology. The small size, long life and high specificity of the sensors are central to the sleek, compact and functional design.

Designed for single pushbutton operation, the GasAlertMicroClip comes complete with sensors, a dependable lithium polymer rechargeable battery, charging adapter capable of completely recharging the battery within three hours, interactive training CD, test cap, manuals and quick reference card. Optional Confined Space Kits additionally include an IR Connectivity Kit for data downloading and instrument setup, remote sampling kit with 10' sample tubing and probe, calibration gas, regulator, fittings and foam-lined carrying case.
