CALYS 75 is a field documenting multifunction calibrator of high accuracy 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 75 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 0,014% RDG
- Resistance: Up to 0,012% RDG, 4 KΩ range
- Current: Up to 0,0175% RDG, 50 mA range + 24 V loop supply
- Voltage: Up to 0,013% RDG, 50 V range
- Frequency: Up to 0,005% RDG, 20 KHz range (10 KHz in simulation)
- When used with an external pressure module (ref. ACL433), CALYS 75 can measure and simulate pressure (comparison calibration with a pressure pump).
Specifications and performances in temperature @23°C ±5°C
Uncertainty is given in % of reading (CALYS 75 display) + fixed value.

Thermocouples: D and G, for specifications, refer to the instruction manual (Available on request)
Accuracy is given for reference @ 0°C.
When using the internal reference junction (except couple B) add an additional uncertainty of 0.2 °C at 0 °C.
It is possible (thermocouple B excepted) to choose by programming the cold junction localization: External at 0°C, internal (temperature compensation of instrument’s terminals) or manually entered.
