  propane, hydrogen
• Proven over decades for life support in US
  coal mines.
• Expand system safety by adding toxic and smoke
  detectors.
• Monitors natural gas without the ethane
  exaggeration with optical sensors.
• MagiKal - automatic sensor calibration Computer
  scheduled and Cal-Now for 2- years, unattended.
• Rel-Tek has the first and only MSHA
  approval to use auto-cal in mines.
• AC plus 100W solar panel includes ample battery
  backup.

The Biggest Cost Savings of All ...!
Over stating your methane, greenhouse
gas emissions is not a good thing.

• Rel-Teks wide-spectrum GasBoss sensors properly
  account for all combustible constituents of NG,
  including methane, ethane, propane and hydrogen
  -- as they actually contribute to the LEL. There
  is no over-reaction to ethane.
• The ethane catastrophe was discovered by the
  British decades ago wherein optical sensors
  inherently overreact to ethane. The worlds coal
  mines use catalytic bead sensor technology to
  avoid such errors from optical (NDIR) devices.
• Optical (NDIR) sensors widely used on Marcellus
  gas wells typically over-react to the inevitable
  ethane content of NG, exaggerating the methane
  greenhouse gas emission by a factor of 20x. This
  is due to the huge optical footprint of ethane
  making just 1 ethane read as 20 methane.
• Solution Eliminate undeserved fines and
  assessments for ethane-inflated greenhouse gas
  (methane) emissions.
• Total cost savings can be very large figures,
  even exceeding the initial price.
