The typical confined space monitor measures oxygen, combustibles, carbon monoxide and hydrogen sulfide. Will it keep you safe in today’s industrial environment?

The short answer is ‘no’.

When doing confined space you need the added broadband protection of a PID.

The EntryRAE is a 4-gas monitor and photoionization detector (PID) in one small unit. Reliable, easy to operate, and simple to calibrate the EntryRAE delivers added protection without added complexity. Combine a PID and a 4-gas monitor and you have true protection from the unexpected.
