The WIKA CTD9100-165 dry well calibrator is compact and lightweight, making it particularly suited for on-site calibrations. The calibrator combines a stable heat source with precision Pt100 temperature measurement, enabling industrial temperature probes to be calibrated more efficiently. Regular monitoring of temperature probes helps to recognize failures promptly and shorten down times .

The CTD9100-165 operates using Peltier elements for active cooling, allowing it to achieve testing temperatures below ambient. This capability makes it particularly valuable in the biotechnology, pharmaceutical, and food industries where low-temperature calibration is essential. With a temperature range of -35°C to +165°C, it covers a wide variety of industrial applications.

The temperature dry-well calibrators work 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 are displayed simultaneously on a large 4-digit, high-contrast LC display, virtually eliminating reading errors.

Accuracy ranges from ±0.15 to 0.25K with stability of ±0.05K. The large insertion depth of 150mm considerably reduces heat dissipation errors. Heating time is 25 minutes from 20 to 165°C, and cooling time is 15 minutes from 20 to -20°C.
