ECHO28氣體檢測儀

The ECHO 28 controller covers the middle ground between the small controllers like ECHO 2/4 and the larger modular systems such as MDXI. The single unit design keeps the cost down.

Features

Evolutionary unit from 4 to 28 channels of measurement.

Wall mounted or rackable unit designed for an evolutionary solution.

Constant supervision of gases and flammable or toxic fumes.

Constant supervision of the risk of oxygen deficiency.

Application

This unit completes our range of rackable industrial units and perfectly meets the requirements of partly industrialised sites and service sectors.
