MSA ALTAIR 4XR Bluetooth Meter (LEL, O2, CO, H2S)

This is the best sniffer on the market. The best part about it is it’s ease of use. It comes factory calibrated. You take it out of the box, put the batteries in, and turn it on. The sniffer does the rest. It is also very rugged and tough. The company I work for is rough on equipment and these things stand up to the test. They are very tough. We own 8 of these day hints and only use this kind now. Highly recommend this product for anyone looking for a good easy to use sniffer. Oh and by the way the price can’t be beat either.

The Bluetooth upgrade is great. I can monitor and log my readings on my phone real time. Battery life is still great and lasts all day with no problem.

Easy to use, fairly intelligent design, sturdy case that may be indestructible.

Oxygen sensor failed right away amazon was useless by msa sent a new sensor right out under warranty. Seems like a good tester

Light weight and easy to use!

Good product and good price.

Dependable safety tool.

Perfect
