What we do
We represent leading international instrumentation manufacturers in Greece and put their technology to work in real plants: flow, level, pressure and temperature measurement, process analysis, ATEX-certified equipment for hazardous areas, and variable-speed drives.
Our job starts before the order and continues after delivery. We size and select the right instrument for the application, help with installation and commissioning, and stay available for troubleshooting, spares and upgrades throughout the life of the equipment.
Calibration and on-site verification of installed instrumentation are provided by the same company through our dedicated services site, services.semac.gr — the engineers who verify your meter are the ones who understand the application it sits in.

How we work
Five principles shape every quotation, every site visit and every support call.
Integrity
We recommend what the application needs, say so when a measurement is not technically valid, and put it in writing.
Leadership
We bring the manufacturer’s latest technology to Greek plants first — and explain what it changes for the process.
Trust
Relationships with customers and manufacturers that span decades, built on keeping the promises we make on site.
Passion for winning
A measurement problem is a challenge to solve, not a product to sell. We stay with it until the reading is right.
Ownership
Every enquiry has a named engineer behind it, from the first call to the commissioning report.
