The most common portable monitor configuration around is the 4 Gas monitor.  A standard in many industries, the 4 gas monitor measures levels of Carbon Monoxide, H2S, Explosive Gases (usually Methane, but Pentane is a common gas used in Industrial Scientific monitors as well), and Oxygen.  This page lets you quickly and easily order gas to fit these 4 gas monitors.  If you have a monitor and either don't know what gas you need to calibrate it, or you aren't certain what it is currently set for and need help finding out, please Email Us and we'll get back to you ASAP.

 

To use this form, please just fill in the values for each calibration gas and then click add.  Your shopping cart at the bottom of the page will fill with the item.  Shipping on any gas is $7.00 per cylinder, plus an overall $30.00 Hazmat fee.
