What Features Should You Look For in Your Next Gas Monitor?
Thursday, March 26, 2020

When you buy a new gas monitor, you should think of it as getting a new car for the family. You're going to want a product that comes with high-quality safety features as well as functionality so that your family (or employees) will remain safe. But most people don't have experience with gas detectors like how they do with cars.

So how can you determine which gas monitor is the best fit for your situation? Continue reading and we'll walk you through the most important features you need to look out for when buying a new gas monitor.


Everyone should look for a gas monitor that's accurate. However, just because it says "accurate" on the packaging doesn't mean it actually is. With gas monitors, a product's accuracy is given as a percentage of how close it is to reading the actual concentration on the gas monitor.

However, it's up to the discretion of the manufacturer as to whether the "accuracy" is for the full scale of the reading or just a specific portion of it. The "accuracy" of a gas monitor is usually listed with a minus or plus 5%. You want the readings to be within plus or minus 5% of the actual concentration of gas.

It's also important that you calibrate your gas monitor.

Fast Response Times

When you're working in the oil and gas industry, getting a fast response time from your gas monitor is crucial. A fast response time (t90) is letting you know the time it takes for the gas monitor to display 90% of the gas concentration.

Let's imagine that H2S gas is introduced to two different monitors. One of the monitors has a t90 of 24-40 seconds and the other one has a t90 of 15 seconds. Neither of these devices will react immediately.

However, after a few seconds, the device with a t90 time of 15 seconds will start to register the gas concentration. The other device will not have a digital readout until later.

That instrument with a t90 time of 15 seconds will continue to display numbers until it detects 10 ppm. This will all be happening before the other device displays anything at all.

After 1 minute and 35 seconds of gas exposure, the faster device will measure 15ppm and then activate its A2 alarm. The worker with this monitor will know to leave these dangerous conditions.

A worker with the other device will have to wait an extra 42 seconds before their alarm sounds. By then, the gas concentration would have risen to around 20 ppm and the worker would have likely already experienced a range of painful symptoms.

User-Friendly Features

You want your gas monitor to be user-friendly and easy to use. It should be lightweight and comfortable to wear. It should also be portable and not need to be plugged-in to work.

The device should also be able to wirelessly transmit the data it collects to a central command station.

Why You Should Know What to Look for in a Gas Monitor

Gas monitors save lives. However, ones that are unreliable, complicated, or inefficient can have the opposite effect. Just like a family car, you should never skimp on safety or quality when buying a gas monitor.
