The PS500 provides versatile 5-gas detection with smart plug-and-play sensors (including options for VOCs and more), while the PS200 delivers proven 4-gas performance in a lighter package. Both prioritize ease of use, durability, and clear alarming for worker protection in hazardous areas.
(Refer to combined table in Intro 2 above for details; PS500 adds flexible sensor boards, 360° visual alarm, and pump/diffusion switching.)
Shipping (enclosed spaces), wastewater treatment, petrochemical, brewing, plant maintenance, tunneling, and permit-required confined space work.
Alarm fatigue in noisy settings (PS500's loud 95dB helps), sensor poisoning in certain environments (use appropriate filters), or data management—both support logging for compliance.
PS200 as cost-effective 4-gas option; PS500 for advanced multi-gas and VOC monitoring.
