The Heath Malmstadt-Enke EUW-402M Polarography Laboratory . . . (developed by Dr. Christie Enke of Michigan State University) consists of a highly versatile Dropping Mercury Electrode Apparatus (Heath EUA-19-6); a combination of a Polarography Module (Heath EUA-19-2) and Operational Amplifier System (Heath EUW-19B), which produces the precision controlled electrode voltages and accurate current readout; and a Multi-Speed Servo Chart Recorder (Heath EUW-20M), which provides accurate display of the readout signals over a wide range of time bases. The electronic control instrumentation produces a sweep potential in six 1% calibrated sweep rates from 0.05 to 2 volts/min. and enables d.m.e. currents from 0.5 to 1000 microamperes full scale to be accurately measured. The Heath EUW-402M Polarography Laboratory includes many additional features not found in the most expensive polarographic systems.
The Heath Malmstadt-Enke EUW-301M Multi-Speed pH Recorder and Recording Electrometer Fulfills Many Roles . . . it can be used as a general purpose laboratory pH meter with accuracy as high as 0.005 pH . . . it can be used as a Multi-Speed Recording pH Meter for titrating, monitoring chemical reactions, or for controlling laboratory apparatus . . . and it can be used as a highly accurate measuring or recording electrometer/ picoammeter for supplying readout from laboratory instruments with impedances as high as 10,000 megohms. These capabilities plus the wide range of chart speeds enable this instrument to perform data readout from a myriad of chemical processes . . . acid-base titration curves, reaction-rate curves, oxidation-reduction titration curves, stability curves, Karl Fischer titrations, and precipitation and complexation titrations to name a few.
