Brand Cropico Instruments

The DO7 Plus is a 10A micro ohmmeter, suitable for applications within aerospace, utilities, cable or machine manufacturers or where a cooling curve is required to plot peak resistance. Sealed in an IP67 case (when closed or IP53, lid open) it is ruggedly constructed to ensure durability.

The DO7Plus microhmmeter has a backlit LCD graphics panel, full QWERTY keyboard, temperature compensation via optional PT100 probe, and built in coefficients for Copper and Aluminium as well as user defined. Full cooling curve facilities are built in, with real time graphical plotting on the LCD.

The Cropico DO7Plus microhmmeter has a display length of 60000 counts and auto averaging of forward and reverse measurement removes thermal emf differences. Connectivity is improved with both USB and RS232 for data downloading. The internal memory holds up to 1000 date and time stamped readings and which can be viewed on the LCD or downloaded with the free software provided, as CSV file to a PC for further analysis.

The included data-log function has the ability to display logged values in a table or graphical format and notes may be added to each logged value. The DO7PLUS also has the facility to automatically measure and calculate cooling curves displaying in both graphical and numeric formats. This makes the DO7PLUS the ideal instrument for machine testing.
