RKI Instruments GX-3R 4 Gas Confined Space Kits / Bundles

RKI Instruments GX-3R 4-Gas Confined Space Kits & Bundles

Product Description

Protect workers with the RKI Instruments GX-3R 4-Gas Confined Space Monitor Kit, a compact, lightweight portable gas detection solution designed for confined space entry, personal gas monitoring, and industrial safety applications. Available in multiple convenient bundles, the GX-3R combines reliable four-gas monitoring with a selection of essential accessories to help simplify equipment setup, calibration, and remote air sampling.

The RKI GX-3R simultaneously monitors four critical atmospheric hazards: combustible gases (%LEL), oxygen (O₂), carbon monoxide (CO), and hydrogen sulfide (H₂S). A hydrogen-compensated carbon monoxide sensor option is also available for applications requiring that configuration.

Weighing approximately 3.52 ounces without its protective rubber boot and measuring just 2.2 × 2.55 × 1.02 inches, the GX-3R is designed to be worn comfortably near the worker's breathing zone. Its small footprint makes it an excellent choice for professionals who need a lightweight, wearable four-gas detector without the bulk of a larger instrument.

Choose the Right GX-3R Gas Monitor Bundle

Select the RKI GX-3R confined space gas monitor bundle that best matches your workplace requirements and gas detection procedures:

• GX-3R with Charger and Hard Case: A convenient option for portable gas monitoring, charging, and equipment storage.

• GX-3R with Charger, Hard Case, and Calibration Kit: Adds calibration equipment to support routine instrument maintenance.

• GX-3R with Charger, Hard Case, and Remote Sampling Pump: Includes a remote sampling solution for applications where air samples need to be drawn from a location away from the operator.

• GX-3R with Charger, Hard Case, Remote Sampling Pump, and Calibration Kit: A more comprehensive package for teams that need both remote sampling capability and calibration equipment.

Review the selected bundle's included accessories before ordering to ensure it meets your operational requirements.

Key Features and Benefits

Four-Gas Detection in One Compact Instrument

Monitor combustible gases, oxygen, carbon monoxide, and hydrogen sulfide simultaneously with a single portable gas detector. The GX-3R helps workers identify potentially hazardous atmospheric conditions during confined space entry and other industrial operations.

Lightweight, Wearable Design

At approximately 3.52 ounces without the protective boot, the GX-3R is designed for convenient personal monitoring. Its compact dimensions allow it to be clipped near the worker's breathing zone for practical, on-the-job use.

Advanced Microsensor Technology

The GX-3R uses advanced sensor technology, including a dual-filament combustible gas sensor designed to improve resistance to silicone poisoning. Its electrochemical oxygen sensor is designed for an expected service life of approximately three to five years under suitable operating conditions.

Audible, Visual, and Vibration Alarms

Multiple alarm methods alert users to gas alarm conditions. Three adjustable alarm levels, a large LCD with automatic backlighting, and straightforward two-button operation help make the instrument practical for demanding work environments.

Non-Compliance Indicator

The GX-3R features a visual indicator that flashes its LEDs at an adjustable interval when a bump test has not been performed, calibration is due, or a gas alarm event has occurred. This provides a useful reminder to address instrument status before continued use.

Extended Battery Operation

The rechargeable lithium-ion battery provides approximately 25 hours of operation under specified conditions, helping reduce interruptions during work shifts. Actual runtime depends on operating conditions and instrument configuration.

Durable Construction for Industrial Environments

An impact-resistant body with a removable protective rubber boot and an IP66/IP68 dust- and water-resistance rating help the GX-3R withstand demanding field conditions when used within its specified limits.

Field-Replaceable Sensors and Filters

Replaceable sensors and filters support ongoing instrument maintenance. The GX-3R also includes data-logging capabilities for recording information such as user IDs, calibration and bump-test history, and alarm events.
