Profile: SPAC Systems manufactures precision measuring instruments, gauges, fixtures and metrology products. Our calibration lab equipments include dial & granite comparator stands, granite/C.I. surface plates, angle plates, magnetic V blocks, magnetic dial stands, and precision inspection bench center. Our testing apparatus includes ultrasonic thickness gauge, torque wrenches, shore hardness, roughness, dial calibration & Poldi hardness tester, IR thermometer and tachometer. Our angle plates are versatile tools for layout, machine set-ups, tooling and inspection. These can be used as right angles/squares. Matched pairs can be used as parallels and height blocks. A job can be fixed with one of the faces and rotated in five planes without the need for repositioning/disturbing the setting. Our granite/C.I. surface plates are useful for precision gauging, inspection, layout and marking purposes. They are preferred by precision tool room, engineering industries and research laboratories. Torque wrenches are used for precision tightening of bolts and nuts to preset values. Graduated on triple scale in KG/M, LB-FT and NM, the required torque is set by pulling a Tommy bar. We are also specialized in repairing, servicing and calibrating precision measuring instruments.
