Large and easy-to-readThree-color
LCD screen

Normal screen (green)
Caution screen (orange)

Danger screen (red)

Identifiable detection stateaway from the display!

POINT2

 p to 20 m of remote sensing
Uby a remote sensor (optional)Install the sensor at a location with possible leakage ofgas and check the concentration in a separate safe area.
Four cable length : 3 m, 5 m, 10 m, 20 m.

POINT

3Line up of three specifications for power supply

S pecifications can be selected for “AC powersupply”, “DC power supply” and “dry battery”
depending on the installation place.
2 dry batteries fitting into the monitor require noextra space.

Toxicity of Carbon Monoxide on Human

Body Design

Concentration (unit: ppm)

Toxicity

25

Concentration in the air which is not considered that repeated exposure during normal 8hours workday
and a 40hours workweek, TWA allowable concentration recommended by ACGIH, causes healthproblem for almost all workers

Downsizing, renovated design,easier to use!

50

Allowable concentration recommended by Japan Society for Occupational Health, concentration that
does not cause health problem for 8hours workday

100

Concentration that causes no problem except slight discomfort after 5 to 6 hours of exposure200

Mild heaviness of the head/headache in more than one hour of exposure

300

Mild heaviness of the head/headache in one hour

400 〜 500

Mild headache in one hour, moderate poisoning in 3 to 4 hours

600 〜 700

Mild headache in one hour, moderate poisoning in 2 to 3 hours

1000 〜 1200

Mild headache in 30 minutes, moderate poisoning in 1 to 1.5 hours

Buzzer window

Mild to moderate headache in 30 minutes, sever condition in 1 hour, death in 2 hours

3000

Sever poisoning in 30 minutes, death in 1 hour
Danger or death in 30 minutes
