Additional Feature

The OM-CP-QUADTEMP-A is a 4-channel, battery powered, standalone, thermocouple based temperature data logger. The OM-CP-QUADTEMP2000 is the same 4-channel thermocouple data logger but with an LCD display. The OM-CP-QUADTEMP2000 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 readings per channel (channels can be disabled to increase memory).

The OM-CP-QUADTEMP-A and OM-CP-QUADTEMP2000 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 nonvolatile 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 the 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 also be exported to a text or Microsoft Excel file.

Rated 3 out of 5 by from Works but all thermocouple types must be the same The datalogger and software is simple enough to use and the software for this datalogger is better than some of the other software omega provides for other data collection devices. It does exactly what is needed, log data. The major disadvantage of the 4 channel data logger is that all of the channels must be the same thermocouple type. It does not state anywhere on the website, the specification sheet or the manual that all the thermocouple types must be the same. Only after purchase and looking a little deeper, I only found the only place that it was mentioned that all thermocouple types must be the same was in the quick start guide. Now I need to purchase new thermocouples so I can log data from all my thermocouples.
