Asco Instruments: sensors, gas analysis

Industrial technical pole

As part of CFD's industrial technology division, ASCO Instruments produces a range of measuring tools: from pressure transducers to gas analysis.

Industrial measuring instruments

Founded in 1979, ASCO Instruments is a manufacturer of measuring tools. ASCO joined the industrial technology division of CFD in 2012.

ASCO carries out the manufacture of this equipment in its Châteaufort workshop as well as its maintenance, in Châteaufort, or on its customers' sites.

A wide range of products

ASCO has developed a wide range of products: from very high pressure sensors to gas analysis.

ASCO is certified for ISO 9001 and ATEX standards.


ASCO Instruments has been producing force and pressure transducers since its foundation.

Today the range includes voltage, pressure and level sensors.

All these sensors can be used in hostile environments, especially in ATEX (explosive atmosphere) zones.

These sensors are used by the oil industry for drilling, in water treatment, or by the aeronautical and naval industries.

Breathing air

ASCO Instruments' breathing air products come in many forms and meet a variety of needs.

In particular, the company produces air analysers for distribution networks or compressor outlets, ideal for industrial sites.

ASCO also offers analysis racks for oxygen cylinder filling. These bays are for example used by firefighters and scuba divers.

The company has also developed mobile air analysers with remote alarm for asbestos removal sites.

Gas analysis

In addition to breathing air issues, ASCO has invested in a multitude of gas analysis tools, including the following examples:

  • Catharometers measuring helium, methane, hydrogen or carbon dioxide concentrations
  • Oil vapour or VOC (Volatile Organic Compounds) analysers
  • Airborne particle counters (ideal for site applications)
  • Universal or dedicated air flow measurement unit for ATEX zones (explosive atmosphere)
  • Dissolved oxygen and gaseous oxygen sensors
  • Sampling module

These tools are used, for example, in sewage treatment plants, sewers, in the production of biogas or boiler room discharges.
