AimSafety PM400 Series

Advanced, easy-to-use, 4-gas monitor for worker protection in hazardous environments

The innovative new AimSafety PM400 4-gas portable monitor brings enhanced convenience and flexibility to gas detection in hazardous environments. The ergonomic PM400 diffusion gas monitor simultaneously detects up to four gases, including hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2) and combustibles (LEL). AimSafety’s PM400 is easy to use and delivers continuous visibility of gas concentrations for faster, more informed decisions that help protect workers and operational assets which can increase revenue and productivity.

The PM400 LCD display provides real-time gas concentrations and allows plant managers or workers to set high and low alarm set-points for each sensor, and STEL, and TWA alarm set-points for toxic gases. The PM400’s audible, visual and vibrating alarms alert the user of unsafe gas concentrations.

The PM400 IR will operate continuously for up to 60 days on a single battery charge. Standard sensors include: Carbon Monoxide, Hydrogen Sulfide, Oxygen, and either Catalytic Bead or Infrared for combustible gases (LEL).
