1 PRODUCT INTRODUCTION
The NXM Multi Gas series is a diffusion gas monitor that
simultaneously detects up to four gases, including hydrogen sulfide
(H2S), carbon monoxide (CO), oxygen (O2) and combustibles (LEL).
The unit alarms in three ways: visual, vibration, and audible when the
risk occurs. A dual sensor detects both CO and H2S.
The NXM displays real-time gas concentrations with configurable
settings for high and low alarm points for each sensor plus STEL and
TWA alarm points for toxic gases. The unit will operate continuously
for up to 60 days on a battery charge. Sensors for combustible gases
are offered in either Catalytic Bead or Infrared.
1.1 Key Features
• Small and lightweight
• Stores up to 30 Events (Alarms/Bump Tests/Calibration/Data)
• Simultaneously monitors and detects 4 different gases
• Easy-to-read LCD display
• Single button operation
• Rugged housing
• IP67 dust tight and water resistant
• IR sensor is immune to poisoning
• IR sensor detects LEL gases in inert (O2 deficient)
environments
• 60-day use with one 4–6-hour charge
• Configuration via NXI exclusive IR link
• Easy check and calibration via NXI Docking Station
• Combustible (LEL) available with either IR Sensor (P/N
NX90221) or Catalytic Bead Sensor (P/N NX90222)

2 Warnings
• Any unauthorized attempt to repair or modify the product,
or any other cause of damage beyond the range of the intended use
including damage by fire, lightning, or other hazard, voids liability of
the manufacturer.
• Do not use the device if it appears to be damaged.
• Remove any debris from the surface of the sensor, LED, or buzzer
hole before use.
• Test the performance of the gas sensor beyond the alarm level
regularly.
• Test the device on a regular basis to ensure the LED, alarms, and
vibration actions function properly.
• Use the device under the conditions instructed, including the
temperature, humidity, and pressure range. An environment
outside the user instructions may cause malfunction or failure.
• The sensors inside the device may indicate the gas concentration
differently according to the environment such as temperature,
pressure, and humidity. Calibrate the detector under the same or a
similar environment to the specification.
• Extreme changes in temperature may cause drastic changes of
the gas concentration (e.g. using the detector where there is a huge
gap between the inside and outside temperature). Use the device
when the concentration becomes stable.
• Severe pressure or impact may cause drastic changes of the gas
concentration. Therefore, please use the device when the
concentration is stable. Severe pressure or impact may also cause
malfunction in the sensor or the device.
• The alarms are set according to international standards and must be
changed by an authorized expert.
• Charging or replacing the battery should be done in a safe area
where there is no risk of explosion or fire. Changing the sensor
or battery with improper replacements, which are not authorized
by the manufacturer, may invalidate the warranty.
• IR communication should be done in a safe area where there is no
risk of explosion or fire.
• Do not use expired gas cylinders.
• Use certified gas cylinders only.
• Do not use a gas detector which has failed or cannot pass a bump
or calibration test.
