Comtest delivers EMC testing expansion for TREO
Doubling a lab’s measuring capacity in a very short timeframe: another example of the demand for EMC testing chambers in Europe. In this case, we helped our friends at Treo – Labor für Umweltsimulation GmbH, an independent service provider for product and component testing in the Hamburg area in Germany.

With 6 new TEMPEST rooms and various components, our online portfolio is more comprehensive than ever, offering worry-free solutions for the highest level of protection. For example, our TEMPEST-shielded Main Equipment Room meets NATO SDIP-27 requirements and incorporates HEMP protection measures in accordance with MIL-STD-188-125-1. This provides a secure environment for processing sensitive information by reducing the risk of compromising emanations, electromagnetic eavesdropping, and electromagnetic pulse (EMP) effects.
Military, government, intelligence, financial, and critical infrastructure organisations often use TEMPEST rooms to protect classified or confidential information from electronic surveillance and signals intelligence (SIGINT) threats.
Unlike a standard RF-shielded room, a TEMPEST room combines high-performance electromagnetic shielding with specialised power-line and signal/communication filters, shielded ventilation panels, secure cable penetrations, and strict construction standards to ensure that data processed inside cannot be reconstructed or eavesdropped on from outside the facility.
Our TEMPEST Conference Room can accommodate topics ranging from departmental secrets to state and top secret information.
Our TEMPEST Encryption Room is a specially designed facility built to prevent classified information from leaking unintentionally through electromagnetic emissions, power lines, cables, acoustics, vibrations, or other side channels that an attacker could intercept.
We also offer two types of TEMPEST rooms for forensic inspections: one for multimedia equipment and one for vehicles, designed to inspect, analyse, and test vehicles for electromagnetic emissions, covert transmitters, tracking devices, unauthorised wireless communications, and potential information leaks.
Alongside these new TEMPEST rooms and components, you can find our 20 most popular anechoic, reverberation and shielded EMC chambers, as well as chambers and accessories for antenna testing, on our website, with product pages featuring technical specifications and PDF downloads.
