The SENSIT® P400 4-Gas Personal Monitor is a compact, reliable gas detection instrument designed to help protect personnel working in potentially hazardous environments. Capable of continuously monitoring combustible gases (LEL), carbon monoxide (CO), oxygen (O₂), and hydrogen sulfide (H₂S), the P400 provides real-time awareness of dangerous atmospheric conditions so users can respond quickly and safely.
Built for demanding field use, the SENSIT® P400 features a rugged polycarbonate housing with a permanently bonded rubberized protective overmold for exceptional durability. Its large graphic display provides clear, easy-to-read gas readings, while audible, visual, and vibration alarms ensure critical warnings are noticed in noisy or low-visibility environments. The optional Immediate Detection System (IDS) provides an early warning tick-style alert when gas levels begin to rise, offering additional awareness before alarm thresholds are reached.
