Mensor CTR6500 AC Resistance Thermometry Bridge

The Mensor CTR6500 AC resistance thermometry bridge is a high-precision instrument designed for accurate temperature measurement and calibration across a wide range from −200 to 962°C. It is suited for laboratory, commercial, and industrial use, offering stable and reliable performance for demanding measurement applications.

The accuracy of the CTR6500 is enhanced by AC bridge technology, which minimizes thermal electromotive force (EMF) errors and compensates for probe and cable reactance. This results in strong stability over time and varying ambient temperatures, along with low noise and high resolution. The device supports resolution down to 0.1 ppm, 0.001 mΩ, or 0.01 mK, and includes internal 25 Ω and 100 Ω reference resistors, with the option to use external standards.

The instrument supports a resistance range up to 500 Ω and complies with ITS-90, CVD, and EN 60751 measurement standards. It features a multifunction VFD display capable of showing numeric, statistical, and graphical data, including mean, minimum, maximum, standard deviation, and sampling rate. The system can be expanded from 1 to 60 channels via multiplexers, and its solid-state design avoids mechanical relays to improve long-term reliability.
