Courtest of Unfors Instruments


In the last couple of years, BC Group’s ESU-2400 Electrosurgical Unit Analyzer has been in high demand.

The ESU-2400 uses patent pending DFA Technology, which “allows the system to aggressively digitize the complex RF waveforms produced by electrosurgical generators, analyze each individual data point, and provide highly accurate measurement results,” the user’s manual reads.

“Accuracy is the driver, that’s why this product has been so successful,” says BC Group’s Clotfelter.

In the last several years, Fluke has launched the ESA612 and ESA620 Electrical Safety Analyzers, along with the Impulse 7000 Defibrillator Analyzer and the TNT 12000 X-Ray Test Tools for testing diagnostic imaging equipment. The products have “proven very successful,” Ivankovich said.

When it comes to the responsibilities of designing X-ray test equipment, the job is only getting harder. Diagnostic X-ray manufacturers are continuously changing their devices to improve on their technologies. According to Unfors’ Fitzgerald, today’s test equipment manufacturers have to account for evolving imaging devices that employ lower dose rates, increased filtration and new target/filter combinations.

In January, the company launched the Platinum Plus Edition of its flagship Unfors Xi product. It’s a complete system for multiparameter measurements on modalities such as mammography, dental, R/F and CT. It can simultaneously measure a number of values, including kVp, dose rate, pulse, dose/frame, mA, mAs, time and waveforms. And it comes in a portable package.

“In the old days, service engineers used to have a trunk full of equipment and now they have one silver case that carries around everything they need to do those measurements,” says Fitzgerald.

The company says it’s capable of meeting the needs of service engineers with the contents of an aluminum briefcase because it employs solid state technology.

Unlike ion chamber technology, solid state allows for test equipment to be small and durable. It eliminates the need for manual corrections for beam quality and enables streamlined reporting, since the computer connects to the base. One product also performs all of the measurements.
