Environmental measurements

Due to their industrial activities, companies have a significant effect on the environment. In the context of the European policy on sustainable development, they have to comply with the European Union's environmental standards concerning a wide range of aspects: air quality, management of chemicals and waste, water purity, lighting, humidity, air-conditioning, noise reduction, etc.

Environmental and physical measurements in the Chauvin Arnoux Group are organized around three major orientations:

 For all these crucial measurements, the Chauvin Arnoux Group proposes a comprehensive range of instruments and solutions for domestic use, regulatory verification in the construction industry, maintenance of installations and checking of environmental parameters and compliance with the standards. In industry, the installations, ambient air quality, apparatus and production processes can also be tested using Chauvin Arnoux® measuring instrument ranges, as well as Pyrocontrole® controllers and temperature sensors

These regulatory measurements and tests on installations are performed directly on site by expert technicians from our subsidiary Manumesure.

 Precautionary principle: a healthy environment

Whether in a private or professional context, the applicable European regulations define the acceptable thresholds for individuals' well-being and health regarding air quality, water quality, noise levels and electromagnetic emissions from equipment. These regulations concern:

 The food industry and retail sector for control of the cold chain, food storage areas and the environmental parameters (manometers)

 Preventive maintenance of all types of installations (calibrators, tachometers, etc.)

Ambient environment testing to ensure people's comfort and health in offices and collective areas, crèches, hospital accommodation and private housing and check the operation of the air-conditioning and ventilation systems, as well as noise pollution, CO detection, humidity and lighting: luxmeters, sound level meters, thermometers, thermo-hygrometers and CO detectors


Energy saving

In this field, the regulations in France (RT 2005) seek a 40 % reduction in energy consumption by 2020. To achieve this, the air flow-rate, potential leaks, insulation and equipment (lighting, appliances, etc.) must all be checked.

Many energy savings are simple to implement: switching off lights and heating, closing windows, etc. With the right tools for testing, energy losses in housing or industrial premises can also be prevented relatively easily.
Chauvin Arnoux benefits from an extensive offering which is ideal for auditing the systems involved, checking that they operate correctly and assessing their impact on the environment: 
Thermographic cameras for detecting heat losses
Luxmeters for checking lighting

 Safety of equipment and installations

In industrial processes, the multiple electronic systems connected and the often severe operating environments lead to higher levels of harmonic disturbances on the electrical network and electromagnetic emissions.

These disturbances affect the quality of the energy distributed and, sooner or later, cause failures across all the electrical equipment connected to the network. The negative effects of harmonics on the electrical system may can be dielectric, thermal and/or mechanical.
Electrical network analysers or harmonic analysers are then essential to quantify the total harmonic distortion on the network so that a suitable solution can be found.

In this context, via its Chauvin Arnoux®, Metrix®, Chauvin Arnoux Energy® and Pyrocontrole® brands, the Chauvin Arnoux Group has a developed instruments for testing, analysing and supervising electrical networks.

Pyrocontrole commercializes a comprehensive range of HMIs (Human-Machine interfaces) with touch screens, called CPS Touch®, designed to simplify the day-to-day work of operators involved in industrial process supervision. This interface is all you need for centralized real-time supervision of installations. This advanced technology helps to improve productivity while reducing maintenance costs.

Solid-state thyristor relays and controllers handle the switching of the high powers needed by industrial processes. Their solid-state design means there is no wear of the contacts, so they last much longer.

The solid-state relays and controllers in the Thyritop range can be used in a wide variety if sectors for multiple applications, including:

Furnaces and processes for the glass industries,

Chemical and petrochemical equipment,

Retraction tunnels, paint , infrared lamps, thermoforming, and drying,
