T244 Temperature Calibrator

All Tinycal series instruments have a dual function: generation/simulation and measurement. The keys on the front panel of the instrument allow configuration for the generation of set values in engineering units or percentages. The panel keys also allow the generation in jumps that can be programmed from 1 to 30 seconds per jump, which is stored thanks to its 6 configuration keys. The simulation from the instrument – T240 and T250 – can be configured to simulate the sensor response (Pt100 or selected thermocouple type).

The measurement function can be easily selected with the IN/OUT key, as clearly indicated on the display, which indicates the value to be measured. To avoid possible connection or manipulation errors, the measuring circuit is protected against short circuits and external voltages up to 30 V, ensuring a longer instrument lifetime.

All instruments in the Tinycal family offer high precision and high resolution measurements which, together with their ease of use, high reliability and convenient transport, as well as their low weight and small size, make them basic standards in an instrumentation workshop.

A Pt100 probe calibrator with double function: measurement and simulation

The T244 resistance thermometer calibrator belongs to the new range of Tinycal instruments designed by Gometrics. Its new design and its advanced functions make it an ideal instrument for the calibration of Pt100 probes. The keys on its front panel allow configuration for the generation of adjustment values ​​in engineering units or percentages. The panel keys also allow generation in jumps that can be programmed from 1 to 30 seconds per jump, which it memorizes thanks to its 6 configuration keys. The simulation from the instrument can be configured to simulate the sensor response (Pt100 or thermocouple type selected).

La función de medición se puede seleccionar fácilmente con la tecla IN/OUT, como se indica claramente en la pantalla, que indica el valor a medir. Para evitar posibles errores de conexión o manipulación, el circuito de medida está protegido contra cortocircuitos y tensiones externas de hasta 30 V, garantizando una mayor vida útil del instrumento.

Todos los instrumentos de la familia Tinycal ofrecen mediciones de alta precisión y alta resolución que, junto con su facilidad de uso, alta fiabilidad y cómodo transporte, así como su reducido peso y reducido tamaño, los convierten en estándares básicos en un taller de instrumentación.
