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).
Using 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 75 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.
