Anyone searching for Servomex in Belgium, the Netherlands or Luxembourg usually has one of two questions in mind: which Servomex analyser fits a specific gas measurement, or who supplies and services these instruments locally. AAVOS answers both. We are the Benelux distributor for the full Servomex range, from portable oxygen analysers to hazardous-area process analysers for ammonia slip and combustion control, and we provide the installation, calibration and service work that keeps them running.
This guide brings the Servomex range together in one place: what each product family does, which gases and technologies it covers, where it fits in Benelux industry, and how AAVOS supports it after the sale.
Servomex as a manufacturer
Servomex, part of the Spectris group, has built its reputation on gas analysis instrumentation for industrial and process applications. The company's product portfolio spans more than twenty gases and covers technologies ranging from paramagnetic and infrared sensing to tunable diode laser (TDL) spectroscopy, gas chromatography and plasma emission detection. That breadth is precisely why AAVOS carries the brand: few manufacturers offer a comparable spread of measurement principles under a single roof, which simplifies sourcing for clients who need several gas parameters covered by one supplier.
The Servomex product range at a glance
Servomex organises its analysers into five product families. Each targets a different combination of area classification, gas type and measurement level.
| Range | Typical setting | What it covers |
|---|---|---|
| SERVOTOUGH | Hazardous and safe area, fixed process installations | Oxygen, combustion gases, ammonia slip and multicomponent hazardous-sample analysis, including Zone 1/Division 1-rated units |
| SERVOPRO | Safe area, panel or rack-mounted | Multi-gas CEMS, trace and ultra-trace moisture, industrial gas purity and hydrocarbon analysis |
| SERVOPRO ULTRA | Safe area, ultra-high-purity applications | Sub-part-per-billion moisture and oxygen measurement for semiconductor and electronic gas quality control |
| SERVOFLEX | Portable, field or benchtop use | Oxygen, CO and CO₂ measurement for spot checks, medical gas verification and light industrial monitoring |
| Clean Air | Ambient and emissions-related monitoring | Supporting instrumentation for air quality and combustion-related measurement programmes |
Measurement technologies used across the range
What sets Servomex apart is the number of measurement principles available within one manufacturer catalogue. Depending on the analyser, AAVOS can supply instruments based on:
- Paramagnetic and digital paramagnetic oxygen sensing
- Coulometric oxygen sensing for trace and ultra-trace levels
- Tunable diode laser (TDL) spectroscopy for in-situ, cross-stack measurement
- Non-dispersive infrared (NDIR)
- Flame ionisation detection (FID) for total hydrocarbons
- Gas chromatography for multicomponent trace analysis
- Plasma emission detection for ultra-trace nitrogen-in-argon and semiconductor gas purity
- Thermal conductivity and zirconia sensing
Each technology has a natural fit. TDL analysers, for instance, are the usual choice where a fast, non-contact, in-situ measurement is needed in a hot or hazardous stack, while coulometric and plasma-based sensing dominate ultra-high-purity gas quality control, where detection limits reach into the parts-per-trillion range.
Gases covered
Between the five product families, Servomex analysers measure oxygen, carbon monoxide, carbon dioxide, nitrogen oxides (NO, NO₂, NOx), nitrous oxide, sulphur dioxide, ammonia, hydrogen, hydrogen chloride, hydrogen sulphide, methane, total and non-methane hydrocarbons, propane, propylene, argon, helium, nitrogen and moisture (dew point and trace/ultra-trace levels). This range is one of the reasons AAVOS recommends Servomex where a client needs several parameters measured with a consistent user interface and communication protocol across the instrument fleet.
Where Benelux industry uses Servomex analysers
Ports, tank storage and bulk gas terminals
Terminal operators in Antwerp, Rotterdam and along the Scheldt and Rhine corridors use Servomex analysers for oxygen and moisture control in inert gas systems, tank blanketing and vapour recovery, and for gas purity checks during bulk transfer and bottling operations. The SERVOFLEX portables are frequently specified where operators need quick, mobile verification without a fixed installation.
Power generation and combustion monitoring
For power plants and combustion-heavy industrial sites, SERVOTOUGH combustion analysers and the FluegasExact and Laser 3 Plus Combustion instruments support O₂ and combustibles measurement to improve firing efficiency and reduce emissions. The same product lines feed continuous emissions monitoring systems, where NOx, SO₂ and CO data are needed for regulatory reporting.
Chemical and petrochemical processing
Chemical producers around Antwerp, Terneuzen and Geleen rely on SERVOPRO and SERVOTOUGH analysers for process safety and quality control across applications such as ethylene and propylene production, vinyl chloride monomer manufacture, purified terephthalic acid production and ammonia slip monitoring in DeNOx systems. Hazardous-area certified units are standard practice here, given the flammable and corrosive nature of many sample streams.
Industrial gases, air separation and semiconductor-grade purity
Air separation units, hydrogen and syngas plants, and semiconductor manufacturers use Servomex's trace and ultra-trace instruments, including the DF-500 and DF-700 series moisture analysers and the SERVOPRO ULTRA range, to verify gas purity down to parts-per-trillion levels. This is where Servomex's coulometric and TDL moisture technology, alongside plasma emission detection, does most of its work.
Why source Servomex through AAVOS
Buying a Servomex analyser is only the first step. Getting it installed correctly, commissioned to the process, and kept in calibration over its working life is where most of the long-term value sits. AAVOS supports the full Servomex range in Belgium, the Netherlands and Luxembourg with:
- Product selection advice matched to the gas, sample conditions and area classification
- Installation and commissioning on site
- Calibration, preventive maintenance and corrective maintenance
- Training for operators and maintenance staff
- Local technical support and service contracts, without the lead times of contacting a manufacturer's service desk abroad
For clients managing several analysers across a plant, a single regional service contract with AAVOS often replaces multiple manufacturer support agreements, which keeps calibration schedules aligned and reduces administrative overhead.
Frequently Asked Questions
