The WIKA CTD9100-650 dry well calibrator is compact and lightweight, making it particularly suited for on-site calibrations . This high-temperature model generates its temperature with resistive electrical heating and is most appropriate for applications needing testing at higher temperatures, such as exhaust gases measurements on test benches or in power generation.

The CTD9100 series works with temperature-controlled metal blocks and interchangeable inserts. Thermometers are fitted using the inserts, which can be drilled to accommodate the thermometer's diameter. The calibration temperature can be very quickly controlled using just two buttons on the controller. The actual and set temperature of the heating block are displayed simultaneously on a large 4-digit, high-contrast LC display, virtually eliminating reading errors .

The calibrator's block design improves temperature homogeneity at the lower range, leading to smaller measurement uncertainties. The large insertion depth of 150mm (5.91 inches) considerably reduces heat dissipation errors. With a temperature range of 40 to 650°C, accuracy of ±0.3 to 0.8K, and stability of ±0.05K up to 100°C, the CTD9100-650 delivers reliable performance for power generation, laboratory, and machine building applications.
