GX-2009 confined space monitor. Built around high-quality micro-sensor technology, the GX-2012 is RKI’s smallest personal 5 sensor gas monitor with a built in sample pump.

Weighing only 12.3 ounces, two operating modes: Normal (for confined spaces) and Bar Hole.

The GX-2012 can monitor the standard confined space gases (LEL combustibles, Oxygen content, Carbon Monoxide, and Hydrogen Sulfide), and it can also measure 100% volume Methane and dynamically display either % LEL, or % volume with its auto-ranging ability.

The GX-2012 can be used for gas line purge testing as well as standard safety testing.

RKI GX-3R       NEW MAY 2019

OSHA defines the Breathing Zone as a ten inch radius around the workers nose and mouth, and requires that worker exposure monitoring air samples be collected in the Breathing Zone. Air sampling filters may be attached to the collar or lapel. Traditionally this means only a single gas monitor would be small enough for a worker to practically wear a gas monitor In the Breathing Zone. Now there is a 4 gas monitor smaller than many single gas monitors.

GX-3R PRO  NEW MAY 2019

The GX-3R Pro is the worlds smallest 5 gas monitor weighing only 4.58 ounces and fits in the palm of your hand (2.9” W x 2.6” H x 1.06” D). It simultaneously monitors and displays 5 different gases. In addition to monitoring standard confined space gases, LEL, O2, CO, & H2S, the GX-3R Pro has a 5th channel where you can add ppm or % volume CO2 as well as a full line of toxic gases including SO2, HCN, NO2, NH3 and Cl2.An H2 compensated carbon monoxide sensor is also available. Two ofthe four sensor slots have interchangeable sensors providing flexible configurations, which can easily be changed in the field.

GX-2009 confined space monitor is still available in most locations. Weighing only 4.6 ounces, it fits in the palm of your hand (2.75” H x 2.95” L x .98” D). The GX-2009 simultaneously monitors and displays combustibles, oxygen, carbon monoxide, and hydrogen sulfide. The GX-2009 represents the latest evolution of gas detection technology. Advancements include dual audible alarm ports and alarm LED’s on 3 sides of the instrument, so that alarm conditions are obvious from multiple perspectives especially in high noise environments. Other features include a water-resistant and dust proof design with IP 67 rating, an impact resistant rubber over-mold body that is RFI resistant, and a large capacity data logging system included as standard.

This model has two versions and is a combination type portable HC/O2 or CH4/O2 gas detector with an Infrared (NDIR) type sensor and galvanic cell type sensor. These sensors provide accurate detection of HC/O2 (HC version) or CH4/O2 (CH4 version) levels even in N2 and other inert environments. The measuring ranges are 0-100%LEL/0-100 vol% for HC or CH4 and 0-25 vol% for )2 respectively with automatic ranging. The RX-415 has explosion proof and intrinsically safe construction so that it can be used safely in any environment.

• Available to measure from higher concentration (vol%) to lower concentration (%LEL)
• Explosion proof (Detector: Explosion proof, other electrical circuit and pump, intrinsically safe design)
• Available to measure HC/O2, CH4/O2 in N2, inert gas and air with a reliable NDIR method
