CARTRIDGE CARE
Sensor contaminants
Gas sensors are susceptible to contamination by a variety of common chemicals,
reducing or eliminating their sensitivity. Care should be taken when using silicones,
cleaners, solvents and lubricants in close proximity to sensors as exposure may
cause permanent damage to the sensor. If a device is exposed to a new chemical or
compound, it is best practice to bump test and calibrate units to ensure proper sensor
function is maintained.
LEL SENSOR PRECAUTIONS
For safety reasons this equipment must be operated and serviced by qualied personnel
only. Read and understand instruction manual completely before operating or servicing.
With pellistor technology (LEL-P), any rapid up-scale reading followed by declining
or erratic reading may indicate a gas concentration beyond upper scale limit which
may be hazardous.
High o-scale readings may indicate an explosive concentration.
Calibrations must only be performed in areas free of ammable gasses.
Blackline’s NDIR sensor does not detect Hydrogen or Acetylene. Like any gas sensor,
please be sure you understand your potential explosive hazards and choose the
appropriate sensor technology based on these hazards.
Blackline’s LEL-MPS sensor does not require calibration.
