CALYS 100 is a field precision documenting multifunction calibrator within CALYS range. It is the perfect tool for advanced process maintenance and use on test bench in all industries. Suitable for all field and lab measurements, it can simultaneously measure and generate over two isolated channels various signals of temperature, resistance, process, pressure and frequency in one single instrument.

Providing extended functionalities (temperature simulation, scaling, steps, synthesizer, statistical functions…), CALYS 100 makes advanced data exploitation and full data traceability easier, as well as quick access to functions by menus.

The instrument simultaneously measures and simulates:

  • Temperature: Up to 0,012% RDG
  • Resistance: Up to 0,010% RDG, 4 KΩ range
  • Current: Up to 0,012% RDG, 50 mA range + 24 V loop supply
  • Voltage: Up to 0,010% RDG, 50 V range
  • Frequency: Up to 0,005% RDG, 20 KHz range (10 KHz in simulation)
  • Pressure: When used with an external pressure module (ref. ACL433), CALYS 100 can measure and simulate pressure (comparison calibration with a pressure pump).



calys60-calibrationUsing this user-friendly instrument, calibration tasks can be quickly carried out over the whole process chain. Take the 900 g documenting process calibrator to the field with you during the whole week with 10 calibration procedures stored in the device. Run the procedure after connecting the probes to the instrument (Easy connect system®) and save the results for onsite easy and quick calibration.

Back to the office, you can then upload the data on a computer in order to issue customized calibration certificates with dedicated calibration software DATACAL.


IP 54, fully protected by an antichoc rubber holster, CALYS 100 integrates "easyconnect" terminals and a wide backlite display that makes it easy to use in any severe or dark conditions.

Easy connection system®


Connect your probes by simply pushing on the terminal top and insert wires of up to 3 mm or 10 AWG diameter and compensated thermocouple connectors.

Wires are held tight between two brass plates ensuring thermal stability and a very good cold junction compensation for thermocouples. This system also enables 4 mm banana plugs and security connectors to be connected on the terminal top.

Further features

Scaling in measurement and
simulation modes
Scaling allows process signals to be displayed in % of FS or in all other units. This function also allows sensors to be corrected after a calibration.
Relative measurementThe feature allows the following to be performed:

  • Programming a reference value different from the one of the instrument (NUL function)
  • Subtracting aconstant value by measuring or programming it from a measured value (TARE function)
Simulation menuSimulation value is set by entering value on keypad or by changing the specific digit with the cursor.
Square rootIn current measurement and simulation, this function allows taking into account a quadratic signal coming from transmitter of type ΔP.
Statistical functionsContinuous display of average, minimum and maximum value of the signal under monitoring, as well as number of measurements.
Transmitter testTransmitters can be verified using user procedures. 20 procedures can be stored as well as test results. Deviation curves are displayed.
Edition of comprehensive test reports.
Switch testIn temperature or pressure mode, CALYS 100 can control electronic thermostat and pressostat trigger levels.
Ramps generationStarting, ending and length time values of simple or cyclic ramps can be set to do simulation.
Number of ramps can also be adjusted in case of cyclic ramps for any signals.
Steps simulation2 modes are available:

  • Program mode: Starting value, number of steps and length time have to be set
  • Manual mode: The user has about a hundred preset values

In current simulation, the user will have some additional preset values according to the range, corresponding to 0%, 25%, 50%, 75% and 100% from the selected range. Choice is done between 0-20 mA linear / quadratic range and 4-20 mA linear / quadratic range.

SynthetizerWith 100 values manually set, CALYS 100 enables users to draw a generation curve.
Transmitter functionCALYS 100 is able to be used as a transmitter. Measurement input is copied on the output with scaling.
Storage capacityUp to 10 full configurations (Input / Output type, range…)
10,000 data into one or several measurement campaigns, i.e. more than one week work with configurations, measurements, calibration procedures and reports
