The Doto SYS-1 is the rectangular member of the SYS quartz hour-meter family, combining a compact 54 x 32 mm panel format with a wide-range supply of 10-80V DC or AC100-250V. The 6-digit display accumulates 0-99999.9 hours with quartz ±0.01 accuracy while drawing only 0.3W. The housing is sealed against dust and moisture, and the bezel compresses its gasket when fixed through the panel opening, keeping the meter tight on vibrating machinery such as compressors, generators and construction equipment.
