Multi Gas Detectors and what to use?
My department is looking to get all new Multi gas detectors. 5-6 total. Our main concerns are economy of mainmenance and ease of use. We currently use Micro Max units and we have noticed they burn through sensors. Doing some research I have found that MSA offers 3 year warrenties on their sensors and they use less cal. gas for calibration and bump tests. We were looking at ALTAIR 4X or ALTAIR 5X. Both units have thier merits. MSAs have 3 yr warrenties on everything but MicroMax has lifetime warrenties on the electronics. The 4X is diffusion only unless you buy the pump seperate where the 5X has the pump built in.
A few questions,
1) Have y'all used the MSA units? Do you like them? Are they easy to replace sensors, etc.?
2) Are there other units you would reccommend we look at?
3) Would you say a pump is essential? Is diffusion enough?
