CALYS 1200 is a transportable multifunction calibrator with 0.01% accuracy and insulated channels. CALYS 1200 is the ideal solution to simultaneously simulate and measure: voltage, current, resistance, temperature (thermocouple or RTD), frequency and pulse.
Its large graphical dual display with backlight enables INPUT and OUTPUT values to be simultaneously displayed and leads to keyboard simplification. On-line help messages are available at any time in case additional information on displayed options is needed.
Extended functionalities: data processing, customized signal linearization, transmitter function, ramp and step function, relative measurements…
Offered into a compact benchtop housing, the instrument is designed to meet the requirements of instrumentation engineers and quality managers, both in laboratory and in field work. It is widely used in metrological departments, quality-control departments, research and development laboratories and also by maintenance and approval companies.
Advanced flexibility and high performance has been achieved using a 32 bit microprocessor and a fast A/D conversion technology.
Applications:
Due to its outstanding performances and quality, CALYS 1200 meets the requirements of a wide range of applications:
- Accurate measurement for calibration of signal generators such as sensors, voltage and current sources, resistance, and for the verification of general process control instruments
- Temperature simulation, voltage and current sourcing, resistance simulation for calibration of measuring equipment such as chart recorders, logical controllers, PLC analogue inputs…
- Test of signal conditioners or transmitters, using CALYS 1200 simultaneous sensor simulation and output signal measurement capability.
