Who it is for
Four situations where you must measure — not estimate
Pick yours. Each card names the rule, the gas and the Tremon product that satisfies it.
Switchgear operators
SF₆ leak monitoring
Reg. (EU) 2024/573: installed SF₆ switchgear is exempt from periodic leak checks only with a density monitor and automatic alert. Every kg leaked = 24.3 t CO₂e.
→ DM-91 density transducer · IR·SF₆ transmitter
Oil, gas & biomethane
Methane you can prove
Reg. (EU) 2024/1787: find leaks above 500 ppm, attempt repair within 5 days and complete it within 30; measure and report. Biomethane plants need CH₄ + CO₂ at the grid.
→ IR·OEM CH₄/CO₂ channel · TRM-PGA · TRM-EX
Industrial plants
Emissions in the permit
IED 2024/1785 and CBAM: continuous emission monitoring (EN 14181) and verified CO₂ data instead of default values.
→ TRM-PGA multi-gas analyzer · GDC controller
Instrument makers (OEM)
Your instrument. Our NDIR channel.
A calibrated sensing core with an interface contract (Modbus · UART · CAN · 4–20 mA) built into your analyzer or skid. One gas or several.
→ IR·OEM channel — made to spec
Gases
18 gases, one physics
Each gas has a reference page: properties, safety limits, IR band, monitoring practice, regulation and the matching product.
Products
Real instruments with datasheet and manual
Structured by level on the products page: OEM channel → field instrument → system.
How we work
Four steps, one owner
[1] Spec
You tell us the gas, range, conditions and the rule it must satisfy — with the form below, in two minutes.
[2] Build
We design the NDIR channel: optics, electronics, firmware. Our own sensor, not a re-labelled module.
[3] Calibrate
Calibration traceable to national primary gas standards (ISO 17025 method · VSL). A record per unit.
[4] Integrate
OEM board, bench module or field transmitter — with the interface contract you asked for. Re-verification on a planned interval.
Why Tremon
What we do differently
We design and build the NDIR sensor itself — dual-beam + reference channel, heated cell.
Every channel ships calibrated traceable to national standards. The number survives the verifier.
We advertise only what the physics delivers: no NDIR for O₂, H₂, NOₓ — those go to other channels.
An engineer answers, not a sales funnel. NDA before you share process details.

FAQ
Questions engineers ask first
My SF₆ switchgear stays in service after the phase-out dates — what does 2024/573 require?
Periodic leak checks — unless the switchgear has a tested leakage rate below 0.1 % per year and is labelled as such, is equipped with a pressure or density monitoring device with an automatic alert system, or contains less than 6 kg of Annex I gases. The DM-91 is that monitoring device, with the alert on Modbus to your SCADA. Summary, not legal advice.
Which gases can NDIR not measure?
O₂, H₂ and Cl₂ have no usable IR absorption; H₂S in wet gas is masked by water vapour; NOₓ sits outside the strong IR bands. We route those to electrochemical, catalytic or semiconductor channels in the TRM-EX multi-sensor — and do not advertise NDIR for them.
Do you deliver a raw sensor or an integrated module?
Your choice: a ready-to-integrate OEM board, a benched module or a field transmitter. We hand over the interface contract (RS-232 · UART · CAN · Modbus · Ethernet · LoRa · 4–20 mA), not a mystery box.
Is the calibration certificate traceable?
Yes — every channel ships calibrated traceable to national primary gas standards (RvA / ISO 17025 method · VSL, Delft), with a calibration record per unit.
Can it be Ex / hazardous-area ready?
Yes — the TRM-EX family is certified Ex db IIC T6 Gb X; for OEM channels we design the enclosure and compliance path for the zone you name.
Can you ship to our country?
We export from the Netherlands within EU export-control (Reg. 2021/821) and sanctions rules; we self-classify every product and screen every end-user, and do not supply Russia, Belarus, Iran, DPRK, Syria or the occupied territories of Ukraine.
How do we start — and what does it cost?
Use the tap-form above. You get a reply within 24 h, a feasibility read and a price indication; standard channels are quoted per gas and range, custom work as an engineering project. We can sign an NDA first.
