A four-gas instrument covering oxygen, combustibles, hydrogen sulphide and carbon monoxide is the standard confined space entry monitor, and the sensor set should follow the actual hazard rather than habit. The combustible channel is where specification matters most: a catalytic bead sensor is cheap but can be poisoned by silicones and needs oxygen to work, while an infrared sensor tolerates inert atmospheres and does not poison. Confined space entry also needs a sampling pump and tubing.
The more of this you send, the closer the first quotation lands.
