A. Product Overview
The R-Tek RK-111 Multi Gas Detector combines four important gas measurements in one portable instrument. It is designed for industrial environments where personnel need to monitor potentially hazardous gas concentrations before or during work.
The RK-111 measures:
| Gas | Detection Range | Resolution |
|---|---|---|
| Combustible Gas, EX | 0 to 100% LEL | 1% LEL |
| Carbon Monoxide, CO | 0 to 1000 ppm | 1 ppm |
| Hydrogen Sulfide, H2S | 0 to 100 ppm | 1 ppm |
| Oxygen, O2 | 0 to 30% VOL | 0.1% VOL |
The detector operates using a 3.7 V, 2000 mAh lithium battery and is specified for operation from minus 20°C to 50°C at humidity below 95% RH, non-condensing.
Key features listed for the RK-111 include:
- Triple alarm system
- Explosion resistant design
- High sensitivity sensors
- Fast response
- Long operating time
- Charging system
- Durable housing
- LCD display
- Four gas monitoring in a single instrument
B. Working Principle
The RK-111 uses dedicated gas sensors to continuously measure the concentration of the gases supported by the instrument. The measured values are presented to the operator as gas concentration readings.
For combustible gases, the result is expressed as a percentage of the Lower Explosive Limit, or LEL. Carbon monoxide and hydrogen sulfide are measured in ppm, while oxygen concentration is measured as percentage by volume.
The product listing specifies a triple alarm system, allowing the instrument to alert the operator when hazardous gas conditions are detected. The exact sensor technologies and alarm threshold programming method are not specified on the IndustryBuying product page.
C. Why Is the R-Tek RK-111 Used?
Industrial environments can contain gases that are toxic, combustible or dangerous because of abnormal oxygen concentration. A multi gas detector allows workers to check several important atmospheric parameters using one portable device.
The RK-111 can monitor:
Combustible Gas: Helps identify the presence of combustible gases up to 100% LEL.
Carbon Monoxide: Measures CO concentration from 0 to 1000 ppm.
Hydrogen Sulfide: Detects H2S concentrations from 0 to 100 ppm.
Oxygen: Measures oxygen concentration between 0 and 30% by volume.
Because all four measurements are available in one detector, the RK-111 is suitable for workplace gas monitoring and industrial safety inspections where multiple gas hazards may need to be checked.
D. Suitable Buyers
The R-Tek RK-111 can be considered by organizations and professionals responsible for industrial gas monitoring and workplace safety, including:
- Industrial safety departments
- Factory maintenance teams
- Process plant operators
- Safety officers
- EHS departments
- Industrial maintenance contractors
- Gas monitoring service providers
- Utility maintenance teams
- Industrial inspection teams
- Contractors working in environments where combustible or toxic gases may be present
Buyers requiring simultaneous monitoring of EX, CO, H2S and O2 are the most relevant users for this four gas detector.
