The Best Guide to 4 Gas Monitors (Expert Answers)

A 4 gas monitor detects gases such as carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), and combustibles (EX). When air quality is compromised, these devices are used for personal protection. Examples of hazardous gas environments include confined spaces such as tanks, vessels, silos, and tunnels. When the air quality isn't safe, 4 gas monitors warn the user through audible, visual, and vibration alarms. Maritime, oil and gas, construction, mining, water, and wastewater are just some of the industries that make use of 4 gas monitors

What Is a 4 Gas Monitor?

A 4 gas monitor detects carbon monoxide (CO), oxygen (O2), hydrogen sulfide (H2S), and combustibles (EX). These devices typically have a long battery life, large screen that displays gas concentrations, and a belt clip to connect to clothing. The monitors also have LED, vibration, and buzzer alarms.

It should be noted that 4 gas monitors are also known as multi-gas detectors, 4 gas sniffers, 4 gas meters, multi-gas monitors, or multi-gas meters. OSHA describes these instruments as direct-reading portable gas monitors (DRPDG). These terms all refer to a 4 gas monitor device.

 I am vetting inspector working on board ocean going Petroleum and Gas ships.

As a part of my job and to be a good role model to the ships crew, I carry this personal gas detector with me. I bought it 3 months ago. It works perfectly.

Battery - I use it for about 3 hours every ship and it lasts about 3 ships ebfore recharging. I also like that it has a usb recharge and no need to carry a separate bulky charger.

It clips on the boiler suit pocket.

It also looks very stylish.

It does the job from the safety point of view. It arrived with a calibration document valid for 12 months.

I highly recommend it.

Exactly what I needed

My normal unit failed in the field and I purchased this unit with overnight delivery. I opened the package, and found a well built unit that was easy to use, calibrated (with certificate) and ready to charge. I used it the following day and I am hear to tell you about it, so it must have worked, or at least I was in an area where I was safe, and ensured that it was safe due to this product. The only thing I might mention in a negative fashion was, in direct sun light the screen was difficult to read, but in my Sump and indoors, I could read it easily.
I was able to complete my work thanks to this product.

It works and feels quality

I was worried when I bought it because of the price tag, I didnt want to buy some knock off trash that I could have spent 100$ on. I wanted quality. I knew it worked when I breathed on it and it warned me every time. I trust this and will be taking it with me while cave exploring.
