The RKI Instruments 04 Series Single Gas Detectors are compact, reliable devices designed for continuous personal monitoring of hazardous gases in various industrial environments. These monitors are engineered to detect specific toxic gases, including hydrogen sulfide (H₂S), carbon monoxide (CO), oxygen (O₂), ammonia (NH₃), chlorine (Cl₂), hydrogen cyanide (HCN), nitrogen dioxide (NO₂), phosphine (PH₃), and sulfur dioxide (SO₂). Key Features: Extended Operation: Depending on the model, the 04 Series detectors can operate continuously for up to 9,000 hours on two AAA alkaline batteries, ensuring long-term monitoring without frequent battery replacements. User-Adjustable Alarms: Each detector is equipped with three preset alarms that are user-adjustable, providing flexibility to meet specific safety requirements. Comprehensive Alarm Systems: The devices feature visual, audible, and vibration alarms, ensuring that users are promptly alerted to hazardous conditions even in noisy environments. Field Replaceable Sensors and Filters: Designed for longevity, the 04 Series allows for easy field replacement of sensors and filters, minimizing downtime and maintenance costs. Compact and Durable Design: Measuring 2.1 inches (W) x 2.6 inches (H) x 0.9 inches (D) and weighing only 2.8 ounces, these pocket-sized detectors are IP-67 rated for impact, dust, and water resistance, making them suitable for harsh industrial conditions. Intrinsic Safety Certifications: The 04 Series detectors are intrinsically safe, with ATEX and C/US approvals, ensuring compliance with international safety standards. Applications: These single gas detectors are ideal for use in hazardous material handling, mining operations, refineries, petrochemical plants, water and wastewater treatment facilities, pharmaceutical manufacturing, utilities, chemical plants, and fire services. Warranty: RKI Instruments offers a three-year warranty on materials and workmanship, including sensors, for the 04 Series detectors. However, ammonia and chlorine sensors carry a one-year warranty. In summary, the RKI Instruments 04 Series Single Gas Detectors provide reliable, long-term monitoring solutions for a variety of toxic gases, ensuring worker safety across diverse industrial applications.

Product Overview

The 04 Series single gas monitor is designed to operate for many years with field replaceable sensors and filters. The 04 Series can be operated continuously for up to 9,000 hours on (2) AAA size alkaline batteries (depending on model). The 04 Series has 3 preset alarms that are user adjustable. Each version is also equipped with visual, audible, and vibration alarms as standard.

The replacement sensors are inexpensive, easily field replaceable, and are interchangeable with other popular RKI instruments like the GX-3R, GX-3R Pro, and GasWatch 3. Sensors have a life expectancy of over 3 years and are backed by a 3 year warranty.*

Each 04 Series monitor is impact, dust, and water resistant with an IP-67 ingress protection rating. 04 Series instruments are safe for use in hazardous locations, classified as intrinsically safe ATEX/IECEx and by QPS to U.S. and Canadian standards for Class I, Division 1, Groups A, B, C, and D atmospheres.

* 3 year warranty on material and workmanship including sensors (1 year warranty for Ammonia and Chlorine sensors)
