Versatile gas detector for over 30 gases with smart sensor compatibility.
The ATI Porta Sens II Gas Leak Detector is designed for efficient detection of over 30 different gases including toxic, flammable, and oxygen. With sensor compatibility that accepts H10 “Smart Sensor” modules, this unit ensures precise monitoring with accuracy typically within ±5% of the measured value, contingent on the sensor used. It features a backlit graphics LCD for enhanced visibility across diverse lighting conditions and offers three gas concentration alarm levels, alongside low flow and low battery alarms. The device supports both instantaneous and timed sampling modes and is equipped with data logging for up to 12,000 customizable data points. It operates on a D-cell alkaline battery offering 75 hours of operation, with a NiCad rechargeable backup providing an additional 6 hours.

With dimensions of 3.5″ W x 9″ H x 5.5″ D and a weight of approximately 7 lbs, it ensures convenient portability for field use.
Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.
We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.
We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.
