ERESCO 300 MF4-R

Portable High-Magnication X-ray Unit 300 kV Directional Radiating Tube Head

The ERESCO 300 MF4-R combines the

advantage of a high voltage range up

to 300 kV with a by a factor 3 smaller

focal spot compared to GE´s conven-

tional MF4 ERESCO tubes.

This oers excellent penetration, sharper

results and shorter exposures as well as

geometric magnication inspection to

facilitate higher productivity and quality

in day-to-day inspection routines.

The X-ray tube head consists of a sturdy

metal-ceramic X-ray tube and high volt-

age generator integrated into a rugged

compact housing. The air-cooled 300 KV/

900 W end-grounded X-ray tube is ther-

mally protected for extended life.

The high voltage generator generates

high-stability constant potential volt-

age at higher eciency than conven-

tional line frequency equipment.

The unit oers factor 3-5 times expo-

sure time reduction for radioscopic

applications respectively for applica-

tions with CR/Film where geometric en-

largement is required.

The performance of the X-ray tube and

the high voltage generator is continu-

ously monitored for protection and op-

erational safety. An on-board real time

clock facilitates fully automatic warm-up

routines for optimized and time-saving

tube conditioning. The exible connect-

ing cable is heavy-duty and light weight.
