Special caution
1.
This instrument is not explosion proof. This instrument measure combustible gas around lower explosive limit
in this specification. Take enough measure for the measurement.
2.
This instrument measures extremely toxic gases. This instrument exhausts sample gas from GAS OUT. And
sample gas may leak from internal piping. Take enough measure for the measurement.
