LOGARITHMIC DIGITAL CURRENT METER (ITLC)
The hardware and software complex for measuring the signals of chromatographs "Meta-chrome" (complex) is designed to automate the old fleet of chromatographs of the type LHM, model-3700, series "Color", etc. in terms of measuring the chromatographic signal and automating the processing of chromatographic information. The complex consists of two interconnected functional modules: a logarithmic digital current meter (ITLC) and a chromatographic information processing program "NetChrom" (hereinafter referred to as the processing program).
