AOIP CALYS 50 Field Multifunction Calibrator For Basic Use


The CALYS 50 is a basic portable multifunction calibrator from the CALYS range. Resulting from close collaboration with industries, the CALYS 50 integrates all the functions necessary for adjusting and maintaining the process. Suitable for laboratory and on-site use, it is capable of simultaneously measuring and transmitting on 2 isolated channels, different types of voltage, current, frequency, resistance signals as well as thermocouples and resistive probes.


AOIP CALYS 50 is a basic multifunction calibrator within CALYS range. It’s great for advanced maintenance and testing in any industry. Suitable for all field and lab measurements, it can simultaneously measure and generate over two isolated channels various signals of temperature, resistance, process and frequency in one single instrument. it offers extra features like temperature simulation, scaling, steps, synthesizer, and statistical functions. Accessing these functions is easy through quick menus.

Performance Specifications:

  • Temperature: Accurate measurement and simulation up to 0,014% RDG
  • Resistance: Delivers precision up to 0,012% RDG, 4 KΩ range
  • Current: Offers up to 0,0175% RDG, 50 mA range + 24 V loop supply
  • Voltage: Provides up to 0,013% RDG, 50 V IN / 20 V OUT range
  • Frequency: Achieves up to 0,005% RDG, 20 KHz range (10 KHz in simulation)

AOIP CALYS 50 is shielded with an antichoc rubber holster and has an IP 54 rating for protection. It features “easyconnect” terminals and a large backlit display that makes it easy to use in any severe or dark conditions.

Easy connection system
Easily connect your probes by pushing on the terminal top and inserting wires up to 3 mm or 10 AWG in diameter, along with compensated thermocouple connectors. wires are securely held between two brass plates, providing thermal stability and excellent cold junction compensation for thermocouples. This setup also allows for connecting 4 mm banana plugs and security connectors on the terminal top.
