Continuous Emissions
Monitoring Systems
Proven by installations throughout the world, ET can
offer continuous emissions monitoring equipment
suitable for almost every industrial emission and
process control monitoring application.
Monitoring parameters include: SO2, NO2, NO, HCl, HF, NH3, Hg, CL2, CO, CO2,
H2O, H2S, O2, TOC (THC), O3, benzene, toluene, xylene, styrene, formaldehyde,
VOCs, contaminant gases, dust, temperature, pressure and velocity.
With almost two decades’ experience in the field, we not only supply equipment
but also can offer a comprehensive, project management, turnkey service that will
co-ordinate system design, commissioning, arrangement of utilities, back-up power
systems, signals exporting, training, service contracts and maintenance.
