| The GX-Force Portable 4 Gas Detector is a rugged and reliable device for monitoring LEL combustibles, O2, CO, and H2S. An internal sample pump, USB charging, and field-replaceable sensors make it a great choice for industrial and field applications.
- Versatile operating modes: Normal sample draw and leak check modes for efficient and accurate gas detection.
- Wide sample range: Features an internal sample pump of up to 100 feet for flexible and convenient gas monitoring of LEL combustibles, oxygen, carbon monoxide, and hydrogen sulfide.
- Long battery life: Up to 30 hours of operation on a single charge, thanks to the reliable lithium-ion battery.
- Convenient charging and data transfer: USB type-C connection for fast and easy charging and data transfer.
- Ergonomic design: Lightweight and easy to grip, with dimensions of 2.5" W x 6.81" H x 1.85" D and a weight of just 9.87 oz.
- Robust and reliable: IP67-certified water and dust-resistant design, with field-replaceable sensors and filters for extended use.
- Clear and easy-to-read display: Large LCD auto-backlit display for clear and accurate readings, even in low light conditions.
- Peace of mind: Comes with a three-year warranty for added confidence and assurance.
