Understanding the GasAlertMicroClip XL Part Numbering Scheme

The GasAlertMicroClip XL part numbering scheme can look a little intimidating at first.  However, it’s actually quite easy to understand.  When you learn what each of the characters stands for it will be easy for you to construct the correct part number of the configuration you are looking for.

BW part numbers usually consist of a prefix followed by a string of letters and/or numbers.  Different sections are separated by a dash.  The prefix is specific to each instrument.  For example, the GasAlertMicroClip XL starts with MCXL.  So every GasAlertMicroClip XL configuration will start with this. 

The remainder of the part number is broken up into sections separated by a dash.  One section will be for the sensors, another for power options, another for color, etc. 

These sections contain letters or numbers which correspond to the options. 

For sensors, X=oxygen (O2), W=LEL (Combustibles such as Methane), H=Hydrogen Sulfide (H2S), M=Carbon Monoxide (CO).  If a sensor is not installed then it is symbolized with a zero (0).   Sensor channel 1 is for O2, channel 2 is for LEL, channel 3 is for H2S, and channel 4 is for CO.

So if you are looking for a 2 gas version with O2 and LEL sensors the part number would be the prefix MCXL plus the sensor combinations.  In this case it would be XW00.  The X designates an oxygen sensor and goes into the first channel, the W designates an LEL sensor and goes in the second channel, and the two zeroes show that the H2S and CO channels are empty and these go into channels 3 and 4 respectively.  

So far this gives us MCXL-XW00

The next section of the part number is for the color.  BW sells the XL in either Yellow or Black.  Yellow is Y and Black is B.

The final section is the region.  Since BW Technologies products are sold all over the world there are different part numbers for each region.  These different part numbers take into account the different voltages and plug types around the world.  The most common is NA which stands for North America.  Other region codes are EU for Europe, UK for the United Kingdom, AU for Australia, and CN for China/New Zealand.

So putting this all together if we want a GasAlertMicroClip XL with 2 sensors (O2, LEL), in Black, for North America would yield a part number of MCXL-XW00-B-NA.
