MODEL: HA-LS-210 [Name: Open path gas detector] MODEL: HA-LS-210 Name: Open path gas detector Open path gas detector Protection level: Safety Integrity Level: Explosion-proof mark: FUNCTIONS FEATURES B Ultra long distance monitoring range B Only single-sided power supply and wiring are required B Support uploading PLC/DCS and other systems B Backend computer monitoring B Sound and light alarm B IP68 dustproof, waterproof, explosion-proof This device uses the principle of ultraviolet irradiation and spectral absorption to measure gas concentration. When ultraviolet light passes through H2S gas, H2S molecules absorb ultraviolet light at a specific wavelength. The intensity of the absorbed light is proportional to the logarithm of the volume concentration, transmittance, and temperature of H2S, and inversely proportional to the length and pressure of the measurement cell. The concentration of H2S gas is calculated by comparing the ultraviolet light at the receiving end Sensor types Laser, Ultraviolet, Infrared The equipment is manufactured using high-performance detection components and computer micro-control technology, combined with advanced fully automatic mounting technology.
