Explosimetric cell 

 
This removable, interchangeable and intelligent cell unit can detect explosive gases in the range 0 to 100% LEL and/or 
0 to 100% by volume, as applicable. 
It is equipped with a cell body and filaments, and 

must

 be positioned in the MX 2100 as indicated above.

Toxic gas and oxygen metering cells 

 

These removable, interchangeable and intelligent cell units are fitted with an electrochemical cell and electronic 
components, including an EEPROM memory in which OLDHAM has stored the cell's specific characteristics 
(measuring range, various correction coefficients, STEL and TWA alarms, date of manufacture, serial number, etc.). 
Another item of data called the "wear rate" is used by the MX 2100 to automatically determine the optimal time to 
replace the cell. 
These types of cell unit are therefore also referred to as "intelligent units". They are positioned as indicated above (see 
section 2.1). 
 

2.4.

 

DETECTION OF “VERY HEAVY” EXPLOSIVE GAS  

 
The explosimetric cells of the Oldham portable detectors detect most explosive gases.  However, for “heavy” gas and 
vapours (with vapour density over three), it is mandatory to use a pump (manual or automatic) and/or to remove the 
protective filter located on the explosimetric cells, in order to improve the detection speed. 
 

"ALL GAS" RANGE  

This function is particularly adapted to explosive gases with a density lower than three.  For heavier gases or vapours, it 
is mandatory to choose a specific range and use a pump (manual or automatic) and/or to remove the protective filter 
located on the explosimetric cells, in order to improve the detection speed.
