1. Product Overview
The Induskey SGA600 is a compact, lightweight handheld gas detector of the SGA-600 series, designed for personal and patrol-type gas measurement. With one-button start-up and no chemical reagents required, it measures gas concentration in air in real time; when the measured gas reaches a preset alarm point, the unit automatically issues audible and visual alarms together with an on-screen text prompt. Temperature & humidity measurement, data storage, and smart light-sensor control are available as options.
Depending on the target gas, the detector operates on electrochemical, catalytic combustion, infrared, PID (photoionization), semiconductor, or optical waveguide sensing principles, covering more than 1,000 combustible, toxic, and volatile gases. Three sampling versions are offered: SGA-600A (natural diffusion), SGA-600B (active pump-suction, 400–600 cc/min), and SGA-600C (pump-suction with a 950 mm telescopic probe rod) — the pump and probe versions allow sampling before entry into pits, tanks, tunnels, and other confined or hard-to-reach spaces.
With an intrinsically safe Exib IIC T4 Gb rating and IP65 protection in a high-strength ABS+PC housing of only 190–290 g, the detector is carried by inspection personnel or held at the measurement point — solving personal exposure monitoring and leak-source localization where fixed transmitters cannot reach.
