ECHO 2/4
Compact and reliable stand-alone controllers. Gas detection units ECHO 2 and ECHO 4 are designed as optimum solutions for small installations.
Features
- Detection units with 2 or 4 channels of measurement.
- Wall mounted units combining easy installation and true simplicity of use and maintenance.
- Constant supervision of gases and flammable or toxic fumes.
- Constant supervision of the risk of oxygen deficiency.
Application
Linked with the sensors of the ECHO range of products, these units perfectly fit partly industrialised sites or service sectors such as laboratories, boiler rooms, purification plants and treatment of the water, solvents storage areas, etc., while respecting fundamental safety rules.
