Hi Bethany,

No. This is a self contained unit. You might try something like this:

along with a raspberry pi. Good luck.

Thanks, Andy. Do you know if this monitor has a relay switch? Our safety officer is wanting to wire this so that the vent switches to full-on if the alarm goes off.

Hi Bethany,

We have two of these in the lab:

https://www.grainger.com/product/BW-TECHNOLOGIES-Single-Gas-Detector-4KEE8?searchBar=true&searchQuery=4KEE8

It has a loop to hang it. I also carry it around and hold it close to fittings periodically to check for leaks. Batteries last about a year when left on continuously.

?Hi everyone,
I'm looking for an inexpensive wall monitor for sulfur dioxide that will generate a visual and audible alarm at a given set point. (2-5ppm, as per OSHA exposure limits). Any suggestions?
Thanks,
Bethany?
