The Macurco Single-Gas Monitor Series is designed to continuously monitor the ambient environment and notify
the user if the level of the target gas reaches the alarm set point for the monitor. The device is designed to operate
for two years and then be disposed of according to local regulations. The Macurco Single-Gas Monitor is available in
three versions CM-1, HS-1 and OX-1 to monitor either Carbon Monoxide (CO), Hydrogen Sulfide (H2S) or Oxygen (O2).
The components of the Macurco Single-Gas Monitor are assembled in an ABS/PC plastic housing. Located on the
front face of the unit is an ON/MENU button, the display (LCD), sensor inlet, audio alarm opening, visual alarm LED.
On the back of the instrument is an alligator pocket/belt clip and a label containing the intrinsic safety information
and serial number.
An internal microprocessor controls the indication and alarm functions in response to the signals received from an
electrochemical sensor permanently mounted inside the unit. When turned on, it continuously monitors the ambient
air that enters the sensor through the sensor inlet opening by the process of passive diffusion. If the level of the target
gas detected by the sensor reaches a preset alarm point, the unit will alarm (see the specifications section).
