Description

Hydrogen (H2) is the lightest and most abundant chemical element in the universe. On Earth, it almost always exists in compounds (H2O, or hydrocarbons), but it can be produced and used as a gas in various industrial settings. It is a colourless, odourless, and tasteless gas.

Key Properties:

  • Colourless, Odourless, Tasteless: Undetectable by human senses.
  • Extremely Flammable/Explosive: This is its most significant hazard. It has a very wide flammability range in air (4% to 75% by volume) and a very low ignition energy, meaning it can easily ignite and cause explosions.
  • Non-toxic (Asphyxiant): Hydrogen itself is not toxic. However, in high concentrations, it acts as a simple asphyxiant, displacing oxygen in an enclosed space and potentially leading to suffocation.
  • Very Light: It is significantly lighter than air, so it dissipates very rapidly outdoors or in well-ventilated areas, but can accumulate in unventilated high points within enclosed spaces.
  • Cryogenic Liquid: When cooled to extremely low temperatures (below -253 °C or -423 °F), it becomes a liquid (liquid hydrogen, LH2), which is used for energy storage and rocket fuel.

The table above reflects the percentage response provided by the sensor (top row) when exposed to a known concentration of the target gas (column 1).
The numbers were measured under these environmental conditions: 20 °C (68 °F), 50% RH and 1 atm.
The specified cross-interference numbers apply to new sensors only and may vary with time as well as from sensor to sensor.
“-” means no data available.
This table is given as a reference only and is subject to change.

 

MX6 Replacement Sensor Cells

The MX6 gas detectors include field replaceable, plug-in sensors. The user can replace any sensor in the field and have the instrument in service after performing a simple field calibration. Up to 5 sensor can be installed, each in one or more specific location.
