Dresser* Micro Corrector - MC2

Models ptz + LOG, pt + LOG and t + LOG

This second generation Micro Corrector (MC) takes the
proven MC platform and adds features to enhance the
user experience, functions that can deliver data logging,
and lower operation and maintenance efficiencies, while
retaining the features of the original product.

The Dresser Micro Corrector, Model MC2, can function
as an instrument drive (ID) or wall mount corrector. As a
wall mount model, it can also function as an economical
pressure and/or temperature recorder. Rated for Division
I hazardous locations by Canadian Standard Association

(CSA) and ATEX.
