GasAlert Micro5 series (M5) Expert Product Review:

The Good:

Provides protection from 1-5 different kinds of atmospheric hazards, making it useful in a wide array of applications. It is available either as a standard toxic gas unit, a PID model for detection of VOCs or as an IR model for CO2 detection. It has both alkaline and rechargeable battery pack options, which are field-changeable, providing ease of use. You can also switch from diffusion mode to the optional built-in pump right in the field.


The Bad:

It is pricey, and the huge variety of sensor options, pump and battery options make choosing the right unit configuration a bit confusing for those not familiar with them. I recommend calling us at our toll free number (1.877.766.5412) for assistance in getting the right one.


The Bottom Line:

The GasAlertMicro 5 is highly configurable, which makes it suitable for the widest range of industries and applications. An example of some applications are Wastewater Plants, Pulp and Paper, Airlines, Landfills, Oil and Gas, Food and Beverage, Chemical Plants, Hazmat/Homeland Security and many more! It has many of the same user friendly features as the other units in the BW product line, so it is simple and easy to operate in the field and is a decently small size for its capabilities.


Full Review:

The extensive selection of sensors and user-settable field options in the GasAlertMicro 5 make it one of the most versatile units out there. The new pump design has a visible integrated filter window that allows the user to easily inspect the filter for dirt and debris. This also makes changing the pump filters quick and easy and still provides superior water resistance. AA alkaline batteries or the hot-swappable rechargeable battery pack options allow for fast, safe, and easy battery installation right in the field.

Regular maintenance is required on this model in the form of frequent Calibrations and battery replacement or charging. Bump Tests can also be performed on the unit depending on personal preference or when site safety regulations require it.

Built for rugged environments, the built-in concussion proof boot provides excellent protection against accidental bumps, scratches and damage; and it is water-proof, with an IP rating of 67 it can be submerged in water up to 1 m deep for 30 minutes. The real-time gas concentration is displayed continuously on the LCD so you will always know the current levels, even when the unit is not in alarm. The unit has a built in Datalogging feature, enabling you to retrieve a detailed and accurate history of conditions and unit maintenance if needed.

Calibrating the unit is required every 180 days by factory default but is quick and easy to perform; the procedure can be done in the field and only takes about 2 minutes to perform, and all you will require is a cylinder of calibration gas and a regulator. It is also compatible with the BW MicroDock II calibration and bump test station for those who wish to use a more hands-free, automated, calibration and bump test procedure.
