The OM-CP-OCTTEMP is a 8channel, battery powered, standalone,thermocouple basedtemperature datalogger. This all-inonecompact, portable, easy to usedevice will measure and record upThe OM-CP-OCTTEMP-A is an8-channel, battery-powered,stand-alone, thermocouple-basedtemperature data logger.

The OM-CP-OCTTEMP2000 is thesame 8-channel thermocouple datalogger but with an LCD display. TheOM-CP-OCTTEMP2000 features onscreen minimum, maximum andaverage statistics, as well as a userconfigurable graphics screen thatallows for any combination ofchannels to be displayed.These all-in-one compact, portable,easy to use devices will measureand record up to 500,000temperature measurements perchannel (channels can be disabledto increase memory).The OM-CP-OCTTEMP-Aand OM-CP-OCTEMP2000 are amajor leap forward in both size andperformance. The real-time clockensures that all data is time anddate stamped.The storage medium is non-volatilesolid state memory, providingmaximum data security even if thebattery becomes discharged.

The data logger’s small size allowsit to fit almost anywhere. Dataretrieval is simple. Plug it into anavailable COM port and our easy-touseWindows software does therest. The software converts your PCinto a real-time strip chart recorder.Data can be printed in graphical ortabular format and can be exportedto a text or Microsoft file.
