The OMEGA™ DR130 Series portable hybrid recorder offers high speed
scanning of 20 points/2 sec and high speed recording. This versatile
recorder weighs less than 10 kg (21 lb). Operation is simple, yet powerful
optional computing functions and floppy disk enhance the unit’s
performance. The DR130 uses a high breakdown voltage solid state
relay that permits high scan speed and long relay life without noise.
