pístrojích

Pístrojích is not a standard Czech word. The correct base noun is přístroj, meaning device or instrument. In standard form, the nominative plural is přístroje and the locative plural, used after prepositions such as v or na, is přístrojích. The form pístrojích may appear as a misspelling or typographical simplification in informal writing or OCR errors, but it is not part of formal orthography.

The term přístroj/přístroje encompasses a wide range of devices designed to perform a function, measure, control, or assist in work. It includes scientific instruments, medical devices, electrical appliances, measuring equipment, and other apparatus used in industry, laboratories, homes, and public services. The concept is often discussed in technical literature, product catalogs, and manuals, where precise terminology helps distinguish between devices, systems, and instruments.

Usage and examples: In formal Czech, one would say for example “laboratorní přístroje” (laboratory instruments) or “přístroje v lékařském vybavení” (devices in medical equipment). The locative plural appears in sentences such as “přístroje v laboratoři fungují správně” or “data byla zaznamenána z několika přístrojů.” When writing about devices, authors typically emphasize function, accuracy, calibration, maintenance, and safety considerations.
