Calog Loop II

mA loop Calibrator The Calog LOOP II is the second generation of calibrator in the popular CALIBRATOR range. Using the latest ARM processor, the Calog LOOP II becomes a powerful field instrument, now with the added feature of datalogging.

The Calog LOOP II is a high precision, multi-function, hand-held calibrator designed for the process control industry. It’s speciality is milliamp loop powered instruments which it can measure, source and simulate. DC voltage and circuit continuity can also be measured.

  • Measure, source or simulate 0 to 24 mA
  • Measure 0 to 32 Vdc
  • Continuity test function
  • Increment, step, auto step or ramp with built-in 24V power supply for mA loops
  • Displays values in mA and % or % and mA
  • Trend logging with programmable timebase of all measured values
  • 2 year guarantee against faulty material or workmanship (batteries not included)
  • Selectable Step and Ramp functions
  • 24V internal loop supply
  • Datalogging via SD Card
