At CAS Dataloggers we often receive calls from users needing to make resistance measurement for their applications, for example using string pots to measure movement, measuring thermistors/RTDs for temperature or measuring the resistance on test samples. Resistance is unique in that the measurements may easily span nine orders of magnitude from milli-ohms to mega-ohms which requires the use of different measurement techniques to obtain accurate measurements based on the value being measured. We offer both dedicated dataloggers that are specifically designed for the measurement of RTD’s or thermistors and universal input dataloggers that include voltage or current sources and voltage or current measurement circuits that can stimulate the device under test, measure the response and automatically calculate resistance values.

If you need accurate measurement of small resistances (0-100 ohms) our dataTaker and Grant Squirrel data loggers have the ability to take 4-wire measurements for RTDs or other sensors. These devices both force a current through one pair of wires and then measure the voltage through the other pair of wires. While most of the common measurements fall between the 0 and 100,000 ohm range, specialized sensors such as conductivity or material test samples may require the measurement of very high resistance values. In these cases, we can help you configure a system to allow measurements in to the mega-ohm range.

Below you will find information on our universal data loggers which can measure wide-range resistance along with many other values, or to find the ideal data logger for your specific application, give a CAS Data Logger Applications Specialist a call at (800) 956-4437.
