The RKI Instruments 72-5506RK Gas Detector is a versatile and robust solution for environmental testing and industrial safety. Designed for simultaneous detection of up to six different gases, this detector is equipped with a wide array of field-proven sensors, including infrared (IR) sensors for CO2, % LEL CH4, and 0-100% volume CH4, as well as PPM/LEL hydrocarbon detection. Its powerful long-life pump with a 125-foot range ensures reliable sampling, while the low-flow pump shut-off and alarm provide an added layer of safety. The methane elimination switch allows for accurate readings in environmental applications, and the security adjustment lockout switch prevents unauthorized changes. With up to 30 hours of continuous operation on alkaline or Ni-Cad batteries, the 72-5506RK is built for demanding field use. Its ergonomic, RFI/EMI/chemical-resistant case ensures durability and comfort in harsh environments.
