Description / GX-Force Sample Draw 4 Gas Monitor

Benefits:

Compact and Lightweight: The GX-Force is RKI’s smallest personal gas monitor, weighing only 9.8 ounces, making it easy to carry and wear.

Strong Internal Sample Pump: It features a strong internal sample pump capable of a 100' sampling range, allowing for versatile use in various environments.

Gas Monitoring Capability: The GX-Force can monitor the standard confined space gases, including LEL combustibles, Oxygen, Carbon Monoxide, and Hydrogen Sulfide.

Compatibility: It is compatible with other RKI instruments, such as the GX-3R, GX-3R Pro, 04 Series, and Gaswatch 3, offering flexibility in instrument selection.

Dual Operating Modes: The GX-Force has two operating modes - Normal Operating mode for confined space and safety monitoring, and a Leak Check mode for leak investigations.

Long Battery Life: It operates for up to 30 hours on a Li-ion battery, ensuring extended use without frequent recharging.

Comprehensive Display: The large LCD display provides clear visibility of gas readings, battery level, current time, and automatically backlights in alarm conditions.

Alarm Options: It offers standard alarm types, including vibration, visual, and audible alarms, which can be set to latching or non-latching as per user preferences.

Self-Check and Diagnostics: The GX-Force continuously checks itself for sensor connections, low battery, circuit trouble, low flow, and calibration errors, ensuring accurate and reliable operation.

Flexible Calibration: Users can adjust calibration and bump test intervals and reminders, and the instrument can be set to go into alarm or lock the user out of normal measurement mode once a calibration period has expired. Calibration can be done individually or in a group.

Leak Check Mode: In Leak Check Mode, the GX-Force can monitor for combustibles in the ppm range, making it suitable for leak detection applications.
