The Altair Pro is a single gas detector with the ability to monitor chlorine gas.  It’s ideal for use in industrial applications such as oil and gas, chemicals, steel and iron, utilities, the fire service and contracting work.

It’s a high-performing instrument and features field proven 20 series sensors which are easy to install.  This helps you reduce the down time of the monitor.

You can have confidence that the Altair Pro Cl2 is reliable, robust and features a rugged suspension clip which securely attaches the monitor to your clothing. 

It’s important to test your monitor and this can be done quickly by the push of a button.  The results of the bump check will be shown on screen for 24 hours as a checkmark.  Additional products for testing include the MSA QuickCheck and the Galaxy calibration system – available from Frontline Safety.
