1-2. Intended use
The product is a portable gas monitor for personal use designed to detect gases in the surrounding atmosphere.
It measures concentrations of toxic gases and oxygen in the atmosphere and issues an alarm when gas concentrations
reach preset levels, thereby alerting users to the hazards of gas poisoning and oxygen deficiency.
The detection results are not intended to assure life or safety.
Nine models are available to detect various detection target gases.
Check the specifications before use to confirm the correct gases will be detected in accordance with the intended
purpose.
