Fluke introduces ScopeMeter 190 Series II portable oscilloscopes engineered for harsh industrial environments

Sydney, December 9, 2010 – Fluke Corporation, the global leader in portable electronic test and measurement technology, has introduced the Fluke ScopeMeter 190 Series II handheld portable oscilloscopes, the first four-channel scopes designed for harsh industrial environments.

These new portable scopes are the first safety rated for CAT III 1000V/CAT IV 600V environments.

The four input channels are fully isolated from each other to perform differential floating measurements, a critical consideration for troubleshooting fixed-installation three-phase power electronic devices like variable speed motor drives.

The Fluke ScopeMeter chassis is sealed from the environment with no cooling slots or fans to expose the instrument. It carries the International Protection (IP) -51 dust and drip proof rating so it’s tough enough to use safely on the factory floor and in the field.

The Fluke ScopeMeter 190 Series II oscilloscope meets the growing need for four-channel portable oscilloscopes in industrial environments.

Power electronics are used increasingly in solar and wind energy generation and to maximise efficiency or reduce power consumption especially in heavy-duty electro-mechanical applications. With the new Fluke 190 Series II ScopeMeter, users can see more and fix more using all four channels.

Their fast sampling rate, up to 2.5 GS/sec and 400 pico second resolution, helps users capture electrical noise and other disturbances to diagnose exactly what is going on. With100 MHz and 200 MHz models, they deliver the bandwidth needed to cover both today’s needs, and tomorrow’s.

With four channels, users can inspect input signals, output signals, feedback loops, or safety interlocks simultaneously to solve problems including:
• signal amplitude or shape variations, induced noise or disturbances across critical circuit nodes
• signal timing measurements and synchronisation issues
• attenuation, fluctuation, drift as a result of impedance issues or environmental impacts.

Four channels are indispensable in testing variable speed motor drives and inverter power electronic technology used in green energy generation and transportation applications. Users can:
• view and measure harmonics, transients and loads in three-phase power systems
• troubleshoot dc to ac converters for faulty insulated-gate bipolar transistors (IGBTs) and control circuits
• view and measure pulse width modulated waveforms (PWM) for reflections and transients.

These new test tools are convenient and user-friendly. New, high-performance Li-ion battery technology keeps the Fluke ScopeMeter 190 Series II on the job for up to seven hours. An external charger and easy-access battery door makes it simple to swap batteries and extend usage. Two USB ports, electrically isolated from measurement input circuits, make it easy to capture and share waveforms. Users can conveniently store data to a USB memory device or easily connect to a PC via the USB port and transfer waveforms or screen images for data analysis or archive.

  1. It is great to see Fluke bringing out a 4 channel oscilloscope. The 4ch power scope market has been dominated in Australia by the Tektronix TPS2000 range for many years and now we have a higher spec product in the Fluke 190 series II scopemeter.
