pH/mV calibrator T264


The T264 pH/mV calibrator belongs to the new range of Tinycal instruments designed by Gometrics. Its new design and advanced functions make it an ideal instrument for the calibration of pH probes (pH/mV).

All instruments in the Tinycal series are dual function: generation/simulation and measurement. Its front panel keys allow configuration for the generation of set values in pH or mV units. The panel keys also allow the generation in jumps that can be programmed from 1 to 30 seconds per jump, which are memorized thanks to its 6 configuration keys.

The generation/simulation and measurement function can be easily selected with the IN/OUT key, as clearly shown 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.

Generation/simulation or measurement of the pH signal (pH/mV). Evolution of the SIM-PH calibrator manufactured by Gometrics and backed by more than 25 years of experience. Great tool for checking pH loops (range: 0-14pH).
