Product Overview
The GMI PS200 is a compact, rugged portable gas detector designed for personal safety and confined space entry. It monitors up to four gases simultaneously (LEL flammable, O2, CO, H2S in various combinations) with simple one-button operation. Optional internal pump supports pre-entry sampling while diffusion mode maximizes battery life for ongoing monitoring. Built tough for real-world industrial use with IP67 rating and drop protection.

Application Industry
Commonly used in confined space entry (sewers, tanks, underground piping), shipping and maritime, breweries, plant shutdowns, permit-to-work systems, pressurized tunneling, and fleet operations. Ideal for personal protection against flammable, oxygen deficiency, and toxic gas hazards.
Common Problems
Users sometimes face issues like sensor drift requiring regular bump tests/calibration, low battery in extended use (mitigated by low-power options), or pump blockages in dirty environments. Proper maintenance, hydrophobic filters, and regular checks keep it reliable.
Replacement Models
Compatible with PS200 series variants; sensors are field-replaceable. Consider PS500 for expanded 5-gas needs or additional sensor options like PID/VOC.
