Yokogawa μR20000 18 dot recorder 437118-2

Manufacturer: Yokogawa Electric Corporation

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 high withstand voltage semiconductor relays, and pen servo unit using an ultra-small stepping motor. The versatile display such as multi-channel digital display, bar graph display,  flag display, DI/DO status display, and date/time display  are provided with 181 x 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.)
