WR8500 Series Thermal Arraycorders

Easy Operation High Speed Recording 8 to 16 Channels
The WR8500 series thermal arraycorders are economical, no-frills waveform recorders which feature a large-format LCD screen for waveform monitoring, and a performance level usually found in our more expensive recorders such as the WR9000. Chart speeds up to 200 mm/s are selectable from the front panel, and the sampling rate is a high-speed 4 μs. For users who need increased functionality, we offer a wide range of options such as logic amp input, floppy and MO disk drives, RS-232C and GPIB interfaces, additional memory, DC drive, and a Z-fold chart paper box.

  • Isolation resistance 20 MΩ or more at 500 VDC between the AC power supply and frame, and between the input terminals and frame

    Performance, reliability and ease of use. The WR8500 comes standard with three recording modes to suit your applications: Recorder, Memory Recorder, and Logging. In Recorder mode, the WR8500 displays and records analog signals as realtime waveforms, and it can also capture data into memory simultaneously. Voltage ranges are from 50 mV to 500 V, and logic input is available as an option. In Memory Recorder mode, data captured into memory can be displayed and recorded as waveforms. The WR8500 comes with a standard memory capacity of 64 kwords/channel, and an additional 256 kwords/channel memory is available as an option. In Logging mode, measured data is displayed and recorded as digital values. Data can be captured directly onto a floppy or MO disk. Graphtec's 8 dot/mm thermal array technology enables the information shown on the LCD panel to be accurately reproduced on chart paper. In addition to waveform recording up to 200 mm wide and printing of digital values, you can also print out a list of setup parameters, as well as a hard copy of the display screen. 11 formats are available for the 8- channel model in Y-T mode*2, and a 150 x 150 mm format in the X-Y mode. A selection of 9 grid patterns is also offered.
