OM-CP-OCTTEMP-A & OM-CP-OCTTEMP2000 Series are in the end of their life cycle. As a possible substitute & upgrade, please check out Newest Released 8 Channel Thermocouple Data Logger OM-HL-EH-TC Series for more advanced features with better price.

The OM-CP-OCTTEMP-A is an 8-channel, battery-powered, stand-alone, thermocouple-based temperature data logger. The OM-CP-OCTTEMP2000 is the same 8-channel thermocouple data logger but with an LCD display. The OM-CP-OCTTEMP2000 features on screen minimum, maximum and average statistics, as well as a user configurable graphics screen that allows for any combination of channels to be displayed.

These all-in-one compact, portable, easy to use devices will measure and record up to 500,000 temperature measurements per channel (channels can be disabled to increase memory). The OM-CP-OCTTEMP-A and OM-CP-OCTEMP2000 are a major leap forward in both size and performance. The real-time clock ensures that all data is time and date stamped. The storage medium is non-volatile solid state memory, providing maximum data security even if the battery becomes discharged.

The data logger’s small size allows it to fit almost anywhere. Data retrieval is simple. Plug it into an available COM port and our easy-to-use Windows software does the rest. The software converts your PC into a real-time strip chart recorder. Data can be printed in graphical or tabular format and can be exported to a text or Microsoft file.
