TRM-EX
Four sensing principles, one Ex-certified housing.

Explosion-proof field analyzer (Ex db IIC T6 Gb) with interchangeable sensing heads: infrared for CH₄/CO₂/refrigerants, electrochemical for toxic gases and O₂, thermocatalytic for %LEL, semiconductor for SF₆. 4–20 mA and Modbus RTU.

Applications and the rule behind each
  • Methane LDAR and continuous monitoring on gas installations (Reg. 2024/1787)
  • %LEL detection of LPG / hydrocarbons in ATEX zones (EN 60079-29-1)
  • Toxic-gas workplace monitoring (CO, NH₃, SO₂) at the OEL
  • Hydrogen and battery rooms (electrochemical / catalytic heads)
Gases

Each gas has a reference page with limits, IR band and monitoring practice.

FAQ
Which head for methane?
TRM-EX-IR (infrared) for CH₄ 0–100 %LEL or vol% without oxygen dependence; TRM-EX-CT (catalytic) where hydrogen must also be covered.
Ex documentation?
The Ex certificate and installation instructions ship with the unit; installation by qualified personnel per EN 60079-14.
Calibration interval?
Per gas head — see the datasheet; typically 6–12 months for electrochemical, longer for IR.
