Draeger Pac 3500 H2S 2-Year disposable monitor provides a continuous numeric display that lets you know of hydrogen sulfide gas presence even before it reaches the dangerous levels. This gas detector has a resolution and lowest reading all the way down to 0.1 ppm.

The Pac Detector Communication Module allows data to be loaded onto a PC for analysis and reporting.

This monitor is the traditional silver version. For those who prefer a brighter, more visible option, a yellow version is also available.

Should this diffusion detector come into contact with harmful H2S levels, you'll hear an audible 90 dB multi-tone signal in addition to a vibrating alarm and 360 degree flashing LEDs. There won't be a concern whether or not you'll notice the alarm, and there's two different alarm levels for added safety (10 and 15 ppm). It can also be adjusted to alert you according to whatever standards or company policies you currently have in place by using Draeger's communication module and software.

The Pac 3500 has many standout features, including an incredibly durable and robust housing and D-ring clip that'll survive an impact, a back-lit display for the dark, simple two-button configuration, and an outside filter for easy replacement. It also has the ability to store up to 60 events that can be linked to a computer through a connecting cradle. This will allow you to see when it was turned on and off, calibrated, or even when an alarm went off.

Without proper detection, H2S can kill you in a hurry. That's why so many of our confined space, maritime, and oil and gas customers trust the unparalleled and proven standard of Draeger H2S monitors. Draeger has really made a name for itself because of the quality of the sensors they use, and it's not just in the safety industry.

    How big of an area will this monitor? I am using it in an office to detect gases coming in from a stink pipe through our ventilation system. Basically the air intake on the roof is near the plumbing vent pipes. Is this product what I need to do this?

      This is a diffusion monitor, so it will only detect gas that comes in contact with it (as opposed to a pumped monitor that will pull air samples from a remote location). <br>
      Typically it is worn by a worker going into an area that may contain sewer gases like methane and hydrogen sulfide. However, if you're trying to see if these types of gases are coming into your office area through an air intake, you can place the monitor in front of the air vent, and it will monitor for dangerous gas levels. The gas concentration will be displayed on the screen and the monitor will go into alarm if any of the OSHA thresholds are passed.

    Does this unit have to be bump tested and calibrated?

      This unit doesn't have to be calibrated, but it should be bump tested before each use.

      You'll need a Draeger 0.5 LPM regulator 4557020, a cylinder of calibration gas, hose, and a calibration adapter that fits over the sensor of the unit.

    Does the unit show a reading accurate to 0.1 ppm? For example 4.5 ppm, etc. Or does it round to a whole number.

      The Draeger PAC3500 does indeed have 0.1ppm resolution.
