The Commander PR100 strip-chart process recorder was launched in September 1996. It enabled recording of up to 6 inputs with the option to fit additional inputs, output relays, digital I/O and analog outputs. An inbuilt text printing functionality was standard and optional advanced functions (for example, math, logic, totalizer, RS485 communications and PCMCIA memory card logging) were available.
In May 2000, the PR100 was superseded by the SR100A strip-chart recorder, which in turn became obsolete in January 2015 and was replaced by the ScreenMaster RVG200 paperless recorder. With up to 24 inputs, a 21 CFR part 11 compliant data recording system and clear text display, the RVG200 is the ideal replacement for the PR100. If fewer recording channels are needed, an alternative choice is the ScreenMaster SM500F. This field-mount paperless recorder has the same functionality as the PR100 and the RVG200 but is available with less I/O capability for smaller applications.
