Cropico DO5000 Series Ohmmeters


The D05000 series of digital micro ohmmeters offer flexibility of measurement with high accuracy and exceptional functionality. The D0500 series encompass all the features required in an ohmmeter in one practical instrument.

This series of instruments have programmable measuring current in 100 steps, ensuring that we have a model in the range suitable for your application.

Automatic temperature compensation references the measurement to 20oC and Hi / Lo limits permits sorting of components with the minimum of fuss. The D05000 series all have the ability to take an external PRT 100 sensor, this is easily plugged into the socket on the front of the unit.

All these functions are available as standard as well as a data logging function which stores up to 4000 date and time stamped readings. Statistical analysis of these values allows you to display the Max / Min / Average values as well as the peak to peak and standard deviation.

The range of D05000 instruments is ideally suited for laboratory testing of samples, production line testing, and with the addition of the IEEE-48 or PLC interfaces, the D05000 series may be remotely controlled and integrated into an automated testing system.

When the units are used in the fast measuring mode they can easily do 50 measurements per second.

These features are available on all of the models in the range. The D05001 only differs from the D05000 in that it can be mains and battery powered. The D05002 has a lower current capability than both of the other models.
