The µR20000 is a compact recorder with a recording width of 180mm. The model family consists of 1, 2, 3, 4 pen and a 6,12,18, 24 dot models. Pen model realizes continuous recording for each channel, whereas the dot model realizes a high speed of 6 dot / 10 sec, 12 dot / 15 sec, 18 dot / 20 sec, 24 dot / 30 sec. The input is universal input. High reliability is realized by contact-free technology, such as selfdeveloped high withstand voltage semiconductor relays, and pen servo unit using an ultra-small stepping motor. The versatile display such as multichannel digital display, bar graph display, flag display, DI/DO status display, and date/time display are provided with 181
16 VFD dot display. The µR20000 can be used as a monitoring device and as a quality control instrument in many applications (such as process temperature monitoring, pollution, construction, furnaces, field of medical diagnosis, field of refrigerating, etc.).
