Recently RKI Instruments sent out a notice explaining a change to their alarm settings on Eagle 2, GX-2009, and GX-2012 monitors. In order to comply with new industry standards developed by the fine folks at the American Conference of Governmental Industrial Hygienists (ACGIH), RKI Instruments is lowering their Hydrogen Sulfide (H2S) threshold limit values. These aren't the regular lower level alarms (like someone who writes blogs and has two thumbs first thought). These are the expo …

All gas monitors need to be bump tested, even if they don't require calibration. (Yes, that goes for you guys with single gas disposable monitors too.) To test your monitor you're going to need both calibration gas and a regulator. Your calibration gas mixture will be determined by the type of sensors in your gas monitor. Your regulator will have to fit your bottle of gas. Problem is there are a couple of different types of regulators, and it's not very intuitive figuring out which you'll …

A customer from the Chinese division of a large petroleum company emailed us this week to ask how often their BW Clip H2S Monitors should be bump tested. Since we sell more of these monitors than any other at PK Safety Supply, it would seem logical that we'd have a ready answer. But we don't. It's not because we don't care, or we don't think it's important. It is. Here's the situation: Officially, the manufacturer BW Honeywell recommends periodically testing the response of the hydro …

This is a great question about the BW Clip Extreme H2S monitor, and I'm surprised we haven't had it before. A customer from our website asks "How long of a shelf life does the monitor have?" The answer is each monitor has a unique turn-on date that is set one year after the manufacturing date. The warranty is tied to this manufacture date as well. BW provides a warranty for one year of shelf life plus the two years after activation. If you have a monitor that is past its turn-o …

RAE Systems is the manufacturer of the QRAE 3, the newest multi-gas monitor for confined space entry. Up to four sensors can be configured in this device for combustible gases (LEL), Oxygen (O2), Carbon Monoxide (CO), Sulfur Dioxide (SO2), Hydrogen Sulfide (H2S), or Hydrogen Cyanide (HCN) depending on the specific needs of your facility. The interesting thing about this monitor is the wireless configuration option. RAE Systems says this device will work in confined spaces as well. Fo …

So many single-gas monitors are disposable these days. But not all of them. People buy disposable monitors for a range of reasons. Their workers lose them, or they want a fixed, measurable cost on their books. Some folks just want the cheapest monitor available so they are in compliance with OSHA regulations. But not every company falls into these categories. For companies who are serious about gas detection, the Draeger Pac 7000 single-gas monitors make perfect sense. Financially th …

Gas monitors are sophisticated instruments, but changing sensors is easy. By taking your time and following these simple instructions for replacing sensors, your BW Honeywell monitor will be back in the field in no time. Remember, new sensors require a few hours to burn in - especially the O2 sensor - so don't turn the monitor on right away. Once you restart the monitor, you may receive a "sensor fail" message. Check through your work to make sure you installed the new sensors all the w …

Calibration is very important for a gas monitor. It reestablishes a base line accuracy for the sensors, both electro-chemical and LEL catalytic bead. In order to perform as they were designed, gas monitors need to periodically be readjusted in the same way a guitar string needs tuning. Calibration of your gas monitors isn't difficult or time consuming (unless you have several hundred monitors, in which case it can be very tedious) and it's essential for accurate measurements over time. …
