G50 Portable Gas Detection Alarm

G50 Portable Gas Detection Alarm

Choose the gases and sampling approach for the job, then make alarms and recorded readings easier to review.

  • Sample at the point of concern

    The listed pump and natural-diffusion modes support different sampling workflows; confirm the supplied mode and accessories for the work area.

  • Warn workers in more than one way

    Sound, light and vibration alerts and configurable alarm settings help the wearer recognize changing gas concentrations.

  • Bring readings into the workflow

    Stored records and listed wireless or positioning options can support follow-up when the selected configuration includes them.

Tell us the target gases, sampling distance, alarm policy and required connectivity.

Overview

The portable gas detection and alarm instrument is a high-sensitivity industrial gas detection and alarm device. It is suitable for gas concentration detection in industrial and commercial settings: gas stations, chemical workshops, hazardous materials warehouses, petrochemical sites, laboratories, and other venues. It effectively ensures the safety of personnel and prevents damage to production equipment. The product can detect different gases based on various sensor types. Compact in size, easy to operate, convenient to carry, and with excellent vibration resistance. This product uses high-resolution dot matrix LCD display technology, providing more intuitive and clear visuals. The detection alarm can use either pump suction or natural diffusion methods. The sensitive element is a high-quality gas sensor with excellent sensitivity and outstanding repeatability; the instrument is controlled by an embedded microcomputer, making it easy to operate, fully functional, highly reliable, and capable of various adaptive functions; its compact and aesthetically pleasing portable design not only makes it hard to put down but also facilitates mobile use. The casing of the detector is made of high-strength engineering plastic combined with anti-slip rubber, providing high strength, good feel, and protection against water, dust, and explosion. It is adapted to areas containing explosive gas mixtures in zones 1 and 2 with II A, II B and II C; dustproof enclosures are used for zones 21 and 22
