N2221

The N2221 is a dimensional gauge (electronic microcomparator) of the MICROLIMIT-P modular system, listed in the 1st edition of the Agenda radioelectronistului (1983) among the instruments of IEMI and ICSITE in Bucharest [1].

The 1st edition of the Agenda radioelectronistului (1983) lists the „N-2211/2221” („Microcomparator electronic”, electronic microcomparator) among the electronic instruments for measuring non-electrical quantities of the N-21…N-29 groups, whose producers it gives as „I.E.M.I., I.C.S.I.T.E.” (Bucharest); it does not say which of the two made it; a note says that it is part of the MICROLIMIT-P modular system of instruments for dimensional control and has applications similar to those of the N-2201, except the sorting [1]. Its table gives only a dimensional deviation range of 0…10³ µm [1]. The same entry covers the N2211 [1].
